If you’re looking to put on extra muscle mass and build strength, there are a few things that need to occur. The first of these, even though it may seem obvious, is that you will need to have an exercise routine. To stimulate maximum muscle growth, you’ll need to challenge yourself in the gym, forcing your muscles to adapt to heavier workloads by increasing in size and strength.
When endothelial cells have a higher creatine concentration, they appear to be mildly less permeable when incubated with 0.5-5mM creatine, while the higher concentration (5mM) is able to fully ablate TNF-α-induced neutrophil adhesion and both E-selectin and ICAM-1 expression.[316] This effect was prevented with ZM241385, an A2A (adenosine) receptor antagonist,[316] and since adenosine released by this receptor is known to be protective of endothelial cells,[317][318] it is thought that creatine works vicariously through this receptor and adenosine release, thought to be due to releasing ATP (occurs in response to stress[319][320]) which protects the cell via the A2A signaling system.[316]
Hartman, J. W., Tang, J. E., Wilkinson, S. B., Tarnopolsky, M. A., Lawrence, R. L., Fullerton, A. V., & Phillips, S. M. (2007). Consumption of fat-free fluid milk after resistance exercise promotes greater lean mass accretion than does consumption of soy or carbohydrate in young, novice, male weightlifters. The American Journal of Clinical Nutrition, 86(2), 373-381.
What you eat plays a big role in how much muscle your body can build. Proteins are especially important for building muscle. When you eat protein, your body breaks it down into amino acids which are the building blocks of muscle. How much protein you should include in your diet depends on a number of factors including your age and muscle building goals. Older adults who engage in resistance training and those hoping for maximum muscle growth should eat 1 to 1.3 grams of protein per kg of body weight (2, 3). If you weigh 150 lbs, that means you should take between 68 and 88 g of protein daily. Other recommendations are more modest, suggesting that .36 grams of protein per pound of body weight is enough.
On top of this, you’ll need to consume more calories than you’re burning. Burning more calories each day than you eat is a great way to lose weight, but if your goal is to put on muscle mass, this can make the process much harder. Your body requires calories to build new muscle tissue, but this can’t occur if all the body’s energy is being used up for daily processes. Because of this, some bodybuilding supplements include weight gainers to help you get more healthy calories in your diet.
Cyclocreatine appears to be passively diffused through membranes and not subject to the creatine transporter, which can be beneficial for cases where creatine transporter function is compromised (creatine non-response and SLG6A8 deficiency). Similar to other forms of creatine, it buffers ATP concentrations, although its efficacy as a supplement in otherwise healthy people is currently unknown.
The majority of your workouts should be comprised of compound exercises. Common examples include squats, deadlifts, lunges, bench presses, rows, pull-ups, lat pull-downs, overhead presses, and so on. Isolation exercises should definitely also be a part of your program, just a smaller part in comparison. Common examples include bicep curls, tricep extensions, chest flies, lateral raises, leg curls, leg extensions, calf raises, and so on.
The neuroprotective effects of creatine appear to exist in regard to dopamine biosynthesis, and the suppression of dopamine synthesis seen with some neurological toxins appears to be partially attenuated with dietary intake of creatine. The protective effect is weak to moderate in animal research, but appears to be additive with anti-inflammatories.
Besides the high-quality protein content of casein/whey, the newer formulations have little or no lactose (i.e., milk sugar), which some people have negative reactions to. The native milk proteins also provide a host of smaller proteins called peptides, many of which, such as lactoferrin, have vital health benefits. The rich cysteine content of whey acts as a precursor of glutathione, a primary endogenous antioxidant and liver detoxifier in the body.
Although creatine is a natural component of food, the amount of food required to supersaturate the muscle with PCr may not be feasible. For example, it could require 22 pounds of meat daily [8]. If creatine monohydrate is proven to be a safe and effective ergogenic aid, creatine supplementation may be the simplest way to increasing muscle stores. It may be beneficial to avoid caffeine if taking creatine supplements. One study showed that caffeine diminished strength gains seen with creatine use [9].
One pilot study using 150mg/kg creatine monohydrate for a five day loading phase followed by maintenance (60mg/kg) for the remainder of the five weeks noted that supplementation was associated with fewer muscle symptoms and complaints alongside improved muscular function,[572] yet a later trial trying to replicate the obsevations using 150mg/kg daily for five weeks noted the opposite, that creatine supplementation exacerbated symptoms.[573] 
As you've probably heard from any muscle-bound behemoth you've ever encountered, protein is the key to building muscle. Just because the shake-pounding meathead has become a trope, however, doesn't mean they're wrong; protein really is the fuel your muscles need to grow. That's real capital-S Science, not just bro-science manufactured by supplements companies.
Tough workouts drive muscle growth, but they generally cause a lot of damage to your muscles to do so. This damage often results in soreness for several days, which can make it tough to get to the gym or sometimes even move. Many bodybuilding supplements contain ingredients that work to reduce the breakdown of muscle during workouts, making the recovery process easier on the body.
We’ll be talking more about this later, but for now, just give it a shot! In strength training you can see your progress so clearly that as you can do more and more, you’ll also be rewarded by seeing your strength progress from level 1 to level 50! If you aren’t a fan of the downtime, put on a book on tape or throw on your favorite playlist while circuit training to ensure you’re always moving (instead of sitting and waiting in between sets).
Bodybuilders also understand how to diet. This is perhaps the most important aspect other athletes can learn from. I can’t think of any athlete that comes close to bodybuilders who know how to build massive amounts of muscle and then can diet with the type of precision that gets them absolutely shredded on a specific date. Most resistance training sports use weight classes to compete. It doesn’t take a rocket scientist to see that shedding body fat without losing muscle can be a major advantage. Competing at a lower weight class because you are leaner while maintaining strength and performance is a very valuable and effective strategy. Diet to build LEAN muscle to keep weight low for a competitive advantage.
On top of this, you’ll need to consume more calories than you’re burning. Burning more calories each day than you eat is a great way to lose weight, but if your goal is to put on muscle mass, this can make the process much harder. Your body requires calories to build new muscle tissue, but this can’t occur if all the body’s energy is being used up for daily processes. Because of this, some bodybuilding supplements include weight gainers to help you get more healthy calories in your diet.
The bulking and cutting strategy is effective because there is a well-established link between muscle hypertrophy and being in a state of positive energy balance.[19] A sustained period of caloric surplus will allow the athlete to gain more fat-free mass than they could otherwise gain under eucaloric conditions. Some gain in fat mass is expected, which athletes seek to oxidize in a cutting period while maintaining as much lean mass as possible.

If you're using a resistance band, keep in mind that one band might not cut it for your entire body. Different muscles have different strengths, so you may want to buy two different resistance bands in different thickness, which determines how difficult they'll be to use. In general, if you're able to complete 8 reps of an exercise using a band, you'll want to select another that provides a greater amount of resistance. 
Ballistic training incorporates weight training in such a way that the acceleration phase of the movement is maximized and the deceleration phase minimized; thereby increasing the power of the movement overall. For example, throwing a weight or jumping whilst holding a weight. This can be contrasted with a standard weight lifting exercise where there is a distinct deceleration phase at the end of the repetition which stops the weight from moving.[40]

Creatine has been noted to increase the amplitude (0.5-5mM) and frequency (25mM only) of NMDA receptors, although concentrations of 0.5-25mM also reduced signaling intensity. This was credited to creatine causing an increase in ligand binding of glutamate with an EC50 of 67µM and maximal activity at 1mM creatine (158±16% of baseline).[214] Creatine appears to modulate the polyamine binding site of the NMDA receptor, as it is abolished by arcaine and potentiated by spermidine.[215] This binding site is known to modify NMDA receptor affinity.[216][217]
Those 5-pound dumbbells were a great place to start as a beginner, but if you've been lifting weights for a while, it's time to bump up the weight. “You can use both exercise machines and free weights,” explains Michele Olson, PhD, exercise physiologist, professor of exercise science at Auburn University Montgomery, “but, if you are not lifting heavy enough weight, it doesn’t matter if you are primarily using free weights or machines.” In order to build muscle, you must break down muscle tissue using a weight that is challenging enough to cause micro-tears, which when repaired, form denser, stronger fibers.

Bottom Line: Con-Cret is one of the best creatine HCI products available. Its unique use of creatine HCI allow it to offer all the great benefits of creatine, without the bloating and water retention that creatine monohydrate sometimes causes – making Con-Cret a good creatine to take if you’re concerned about the potential for bloating with other products.
It is regularly reported that creatine supplementation, when combined with heavy resistance training leads to enhanced physical performance, fat free mass, and muscle morphology [18-22]. A 2003 meta analysis [8] showed individuals ingesting creatine, combined with resistance training, obtain on average +8% and +14% more performance on maximum (1RM) or endurance strength (maximal repetitions at a given percent of 1RM) respectively than the placebo groups. However, contradicting studies have reported no effects of creatine supplementation on strength performance. Jakobi et al [23] found no effects of a short term creatine loading protocol upon isometric elbow flexion force, muscle activation, and recovery process. However, this study did not clearly state if creatine supplementation was administered concurrent with resistance training. Bemben et al [24] have shown no additional benefits of creatine alone or combined with whey protein for improving strength and muscle mass after a progressive 14 weeks (3 days per week) resistance training program in older men. These conflicting results can be explained by the possibility that the supplemented groups were formed by a greater amount of non-responders or even because creatine supplementation was administered on the training days only (3 times a week). This strategy has not been adequately tested as effective in middle aged and older men for maintaining post loading elevated creatine stores [5].
If you're a beginner, start with a basic total body strength workout to build a strong foundation in all your muscle groups. Taking this time will help you figure out any weaknesses you have, as well as any issues you may need to address with your doctor, and learn the basic exercises you need for a strong, fit body. Your first step is to figure out where you're going to exercise.

In regard to practical interventions, concurrent glycogen loading has been noted to increase creatine stores by 37-46% regardless of whether the tissue was exercised prior to loading phase.[176] It is important to note, however, that creatine levels in response to the creatine loading protocol were compared in one glycogen-depleted leg to the contralateral control leg, which was not exercised.[176] This does not rule out a possible systemic exercise-driven increase in creatine uptake, and the increase in creatine noted above[176] was larger than typically seen with a loading protocol (usually in the 20-25% range). Consistent with an exercise-effect, others have reported that exercise itself increases creatine uptake into muscle, reporting 68% greater creatine uptake in an exercised limb, relative to 14% without exercise.[153]
A study showed that 100mg/kg creatine monohydrate daily over four months supplemented by boys with DMD is able to enhance handgrip strength in the dominant hand only (less than 10% increase) and increase whole-body lean mass. While the trend toward whole body strength reduction seen in placebo was ablated and there was no interaction with corticosteroids,[560] this study failed to find an influence on activities of daily living or lung function.[560] Elsewhere in children not on corticosteroids with DMD, supplementation of 5g creatine for eight weeks was confirmed to increase muscular phosphocreatine content[554] and according to a manual muscle test (MMT) there was a significant improvement in muscular function relative to placebo, with more parents reporting benefit with creatine (53.8%) relative to placebo (14%).[554]

Squats target both your inner and outer thighs. Use a barbell heavy enough to challenge your muscles but light enough that you can still control your form. Hold it behind your head with your feet shoulder-width apart. Tighten your core, then squat down as far as comfortable. There should be no knee or back pain. As you come back up, raise your hips and chest together.
The first open label trial on ALS failed to significantly alter lung function as assessed by FEV (when comparing the rate of decline pretreatment relative to treatment).[545] Creatine has elsewhere failed to benefit lung function at 5g daily for months relative to control[546] and failed to significantly attenuate the rate of lung function deterioration over 16 months at 10g daily[505] and 5g daily over nine months.[507]

Due to a combination of its neuroprotective effects and dopaminergic modulatory effects, creatine has been hypothesized in at least one review article to be of benefit to drug rehabilitation.[266] This study used parallels between drug abuse (usually methamphetamines) and traumatic brain injury[267][268] and made note of creatine being able to reduce symptoms of brain trauma, such as headaches, fatigue, and dizziness in clinical settings in two pilot studies.[269][270] No studies currently exist that examine creatine supplementation and drug rehabilitation.
Beach muscles and Olympic lifts draw more attention. But the many little stabilizer muscles around your shoulders, hips, and midsection — collectively the core — provide a strong foundation. Challenging the stability and mobility of these key muscles with medicine balls, physioballs, mini-bands, and rotational movements (lifting, chopping) pays huge dividends.
Research shows that strength training is especially effective at raising EPOC. That’s because, generally speaking, strength-training sessions cause more physiological stress to the body compared to cardiovascular exercise, even higher-intensity cardio intervals. However, it’s worth noting that overall exercise intensity is what makes the biggest impact on EPOC. So squats, deadlifts, and bench presses with heavy weights are going to be much more effective at raising EPOC compared to bicep curls and triceps extensions with light weights.
To succeed and thrive as a bodybuilder, it takes more than overwhelming muscular strength or athletic prowess. Judges select bodybuilding champions based on muscle mass, definition, proportion, symmetry, and an athlete’s stage presence. Given the criteria, it is no surprise that most serious bodybuilders consider supplementation to be an essential component of their training regimen.
Weight training has also been shown to benefit dieters as it inhibits lean body mass loss (as opposed to fat loss) when under a caloric deficit. Weight training also strengthens bones, helping to prevent bone loss and osteoporosis. By increasing muscular strength and improving balance, weight training can also reduce falls by elderly persons. Weight training is also attracting attention for the benefits it can have on the brain, and in older adults, a 2017 meta analysis found that it was effective in improving cognitive performance.[38]
Sandow organized the first bodybuilding contest on September 14, 1901, called the "Great Competition". It was held at the Royal Albert Hall in London. Judged by Sandow, Sir Charles Lawes, and Sir Arthur Conan Doyle, the contest was a great success and many bodybuilding enthusiasts were turned away due to the overwhelming amount of audience members.[4] The trophy presented to the winner was a gold statue of Sandow sculpted by Frederick Pomeroy. The winner was William L. Murray of Nottingham. The silver Sandow trophy was presented to second-place winner D. Cooper. The bronze Sandow trophy — now the most famous of all — was presented to third-place winner A.C. Smythe. In 1950, this same bronze trophy was presented to Steve Reeves for winning the inaugural NABBA Mr. Universe contest. It would not resurface again until 1977 when the winner of the IFBB Mr. Olympia contest, Frank Zane, was presented with a replica of the bronze trophy. Since then, Mr. Olympia winners have been consistently awarded a replica of the bronze Sandow.
Another part of training isn't just doing the exercises, it's resting between the exercises. This comes with experience, but the general rule is, the higher the reps, the shorter the rest. So, if you're doing 15 reps, you might rest about 30 to 60 seconds between exercises. If you're lifting very heavy, say 4 to 6 reps, you may need up to two or more minutes.
Before getting into the nitty-gritty details about supplements, it’s important to have a good understanding of how muscle growth works. When you take a muscle growth supplement, the role it plays in helping you reach your goals should be very clear. With the supplements available on the market, you can be sure that while some serve an important purpose, others are gimmicks. It’s easier to identify the money wasters if you know how muscle building works.
In a mouse model of allergin-induced asthma, where mice were sensitized by ovalbumin for three weeks and then given 500mg/kg creatine, supplementation induced an increase in asthmatic hyperresponsiveness to low but not high doses of methacholine.[440] This hyperresponsiveness was associated with increased eosinophil and neutrophil infiltration into the lungs, and an increase in Th2 cell cytokines (IL-4 and IL-5) alongside an increase in IGF-1,[440] which is known to influence this process.[441] Interestingly, there was a nonsignificant increase in responsiveness in mice not sensitized to ovalbumin.[440]

Under most circumstances, sports drinks do not offer a physiological benefit over water during weight training.[18] However, high-intensity exercise for a continuous duration of at least one hour may require the replenishment of electrolytes which a sports drink may provide.[19] Some may maintain that energy drinks, such as Red Bull that contain caffeine, improve performance in weight training and other physical exercise, but in fact, these energy drinks can cause dehydration, tremors, heat stroke, and heart attack when consumed in excess.[20] 'Sports drinks' that contain simple carbohydrates & water do not cause ill effects, but are most likely unnecessary for the average trainee. More recently, people have been taking pre-workout before working out to increase performance. The main ingredients in these pre-workouts are: beta-alanine, creatine, BCAAs (branched chain amino acids) and caffeine.[21]

Creatine is normally metabolized into creatinine (note the difference in spelling), which is eliminated by the kidneys under normal conditions. When the kidneys fail and cannot clear the blood as effectively, many metabolites get “backlogged” in the blood. Creatinine is easy to measure and as such it is a biomarker of kidney damage.[623][624] If serum creatinine levels are elevated, the doctor may suspect some kidney damage. Low-dose creatine (≤5 g/day) may not cause alterations in this biomarker in otherwise normal adults[524][625][525] but high doses of supplemental creatine may cause a false positive (an increase in creatinine, due to creatine turning into creatinine, which does not signify kidney damage) and is a diagnostic error.[520][518][626][523][517] Most studies, however, have noted only a small increase in creatinine levels even with doses ≈20 g/day.[524][626][627]

Whether you’re taking a supplement or not, creatine is already functioning inside you, doing its very important job. It’s an amino acid found naturally in the meat and fish you consume and, according to the Mayo Clinic, your liver and kidneys crank it out as well. The creatine is mainly stored as creatine phosphate in your muscles, ready for use in energy production.
The muscle strength objective is pursued when you want your muscles to be effective when a high number of repetitions will be involved, or in other words when you want your muscles to be strong for a continued period of time. You'll want to use approximately 4 sets from which 10-12 reps are performed. The muscle strength objective is often used for muscles located in your back and your abdominals.
Genetic deficiencies in the creatine biosynthetic pathway lead to various severe neurological defects.[26] Clinically, there are three distinct disorders of creatine metabolism. Deficiencies in the two synthesis enzymes can cause L-arginine:glycine amidinotransferase deficiency caused by variants in GATM and guanidinoacetate methyltransferase deficiency, caused by variants in GAMT. Both biosynthetic defects are inherited in an autosomal recessive manner. A third defect, creatine transporter defect, is caused by mutations in SLC6A8 and inherited in a X-linked manner. This condition is related to the transport of creatine into the brain.[27]
This ingredient also plays a major role in cell growth, recovery, and communication. Increasing the amount of creatine stored in your muscles can speed up the growth of new muscle and help prevent current muscles from being degraded during exercise. By reducing muscle breakdown, creatine can speed up the healing and recovery processes, as there will be less damage to repair.
Creatine has been incubated in various cell lines (HUVEC, C2C12, U937) and noted to reduce cellular death from various pro-oxidant stressors, such as H2O2 or peroxynitrate in an intracellular range between 0.1-10mM. This protective effect was only noted with preincubation and was comparable to 10-100µM of Trolox.[208] This protective effect did not require conversion into phosphocreatine nor a buffering of ATP, and only worked during a preloading to the stressor, rather than in a rehabilitative manner.[208]
While many of the claims are based on scientifically based physiological or biochemical processes, their use in bodybuilding parlance is often heavily colored by bodybuilding lore and industry marketing and as such may deviate considerably from traditional scientific usages of the terms. In addition, ingredients listed have been found at times to be different from the contents. In 2015, Consumer Reports reported unsafe levels of arsenic, cadmium, lead and mercury in several of the protein powders that were tested.[7]

That said, many people experience stomach cramps when they consume creatine monohydrate and it’s possible that taking a creatine with a different pH — usually creatine hydrochloride — can have a different effect on stomach acid and make for a creatine that digests more easily. As far as we know, the easier digestion doesn’t necessarily mean it’s more effective or that you need less of it to achieve the desired result.

Jason Ferruggia is a highly sought after, world renowned strength & conditioning specialist and muscle building expert. Over the last 17 years he has personally trained more than 700 athletes from over 90 different NCAA, NFL, NHL and MLB organizations. He has also worked extensively with firefighters, police officers, military personnel, Hollywood stars and entertainers. Most importantly, Jason has helped over 53,000 skinny guys and hard gainers in 126 different countries build muscle and gain weight faster than they every thought possible.
Studies that use a dosage range typical of creatine supplementation (in the range of 5g a day following an acute loading period) note increases to total body water of 6.2% (3.74lbs) over 9 weeks and[608] 1.1kg over 42 days.[609] Interestingly, some studies comparing creatine paired with training against training itself fail to find a significant difference in percentage of water gained (which is inherently to activity) with standard oral doses of creatine[609][607][610] (although low dose creatine supplementation of 0.03g/kg or 2.3g daily doesn’t appear to increase water retention[611]) despite more overall water weight being gained, due to an equal gain of dry mass in muscles. One study has quantified the percentage increase in mass of muscle cells to be 55% water, suggesting the two groups are fairly equal.[609]
There is some research that suggests that creatine can help people with type 2 diabetes by improving insulin sensitivity, glucose uptake into the cells, and glycemic control. This has led many people with T2 to start supplementing their diets with pure creatine to try and reap the benefits. At this time there has been no conclusive research done into the effectiveness of creatine for type 1 diabetics.

This is one of the best workouts for your hamstrings and glutes. Start in a standing position, feet shoulder-width apart. Hold the bar in front of you. Lower it to just below your knees. You can lower it further if you can keep a flat back and stable spine. Slowly return to the starting position. Keep the bar close to your body to protect your lower back.
At the end of the day, yes, strength training does impact your metabolism, but any boost you get will be minimal and completely secondary to all of the other health benefits of strength training. Any change in metabolism or increase in calorie burn will vary widely from person to person, and depends on so many factors: your genetics, eating habits, health conditions, what workout you do that day, how much sleep you’re getting, and even how stressed you are on any given day. But incorporating a couple of strength training sessions into your fitness routine is worth doing no matter what—you’ll feel yourself get stronger, and put yourself in a position to say healthier throughout life. Those are the best, most promising benefits to work for.

The muscle endurance objective is pursued when you want your muscles to be able to perform the same motions over an extended period of time or in other words when you want your muscles to be strong and not become tired rapidly. You'll want to use at least 4 sets from which at least 16 repetitions are performed. The muscle endurance objective is often used for muscles in your lower body, such as those located in your legs or your buttocks.
SAMe is the primary methyl donor in the human body, and supplements that preserve SAMe (such as trimethylglycine; TMG) promote a variety of benefits in the human body, like a reduction in homocysteine and reduced risk of fatty liver. Creatine has been implicated in both reducing homocysteine[124] and preventing fatty liver in rodents[125], thought to be secondary to preserving SAMe.

More recent studies on the regulation of CrT creatine transport activity have identified the protein kinase (Janus-Activating Kinase 2) JAK2, which suppresses the rate of creatine uptake via CrT without affecting creatine binding.[181] JAK2 is a regulatory protein involved in stabilizing the cellular membrane and controlling water concentrations in response to osmotic stress.[182][183] Similar to c-Src (a positive creatine transport regulator), Jak2 can also be activated by growth hormone signaling.[169][184] The growth hormone receptor seems to activate these two factors independently, as gh-mediated activation of c-Src does not require JAK2.[168] Given that c-Src is a positive regulator of CrT, JAK2 is a negative regulator, and the fact that downstream signals from both are induced by growth hormone, it is tempting to speculate that JAK2 activation downstream of the gh receptor may function as a homeostatic response to limit c-src induced creatine uptake. This has not been studied, however, and the effects of gh-induced JAK2 signaling on CrT activity have not been examined.
It is regularly reported that creatine supplementation, when combined with heavy resistance training leads to enhanced physical performance, fat free mass, and muscle morphology [18-22]. A 2003 meta analysis [8] showed individuals ingesting creatine, combined with resistance training, obtain on average +8% and +14% more performance on maximum (1RM) or endurance strength (maximal repetitions at a given percent of 1RM) respectively than the placebo groups. However, contradicting studies have reported no effects of creatine supplementation on strength performance. Jakobi et al [23] found no effects of a short term creatine loading protocol upon isometric elbow flexion force, muscle activation, and recovery process. However, this study did not clearly state if creatine supplementation was administered concurrent with resistance training. Bemben et al [24] have shown no additional benefits of creatine alone or combined with whey protein for improving strength and muscle mass after a progressive 14 weeks (3 days per week) resistance training program in older men. These conflicting results can be explained by the possibility that the supplemented groups were formed by a greater amount of non-responders or even because creatine supplementation was administered on the training days only (3 times a week). This strategy has not been adequately tested as effective in middle aged and older men for maintaining post loading elevated creatine stores [5].
Weight training also requires the use of 'good form', performing the movements with the appropriate muscle group, and not transferring the weight to different body parts in order to move greater weight (called 'cheating'). Failure to use good form during a training set can result in injury or a failure to meet training goals; since the desired muscle group is not challenged sufficiently, the threshold of overload is never reached and the muscle does not gain in strength. At a particularly advanced level; however, "cheating" can be used to break through strength plateaus and encourage neurological and muscular adaptation.

The pancreas is one of the extrahepatic (beyond the liver) organs that can synthesize creatine, alongside the kidneys.[486][487] Freshly prepared pancreatic β-cells will normally secrete insulin in response to glucose stimulation, and it appears that phosphocreatine is required for this effect, since phosphocreatine is increased in response to glucose[488] alongside an increase of the ADP:ATP ratio. They appear to close ATP sensitive potassium channels (KATP channels), causing a release of insulin secondary to calcium release.[488] Both phosphocreatine[488] and ADP[489] are implicated, but it seems that despite the channel being sensitive to ATP,[490] the concentration of ATP in a pancreatic cell (3-5mM[491][492]) is already above the activation threshold (in the micromolar range[493]) and thus a further increase would not have an appreciable effect.
Creatine supplementation appears to attenuate decreases in GLUT4 expression seen with immobility and may increase GLUT4 expression during exercise. While it seems capable of increasing GLUT4 during resting conditions, it has failed to reach significance, suggesting that creatine supplementation works best with some stimuli associated with exercise.
