In people whose kidneys don’t function optimally, supplemental creatine seems to be safe, too.[513][518][313][528] However, studies in people with suboptimal kidney function are fewer than in healthy people, and they are short-term. People with kidney dysfunction, or at risk for developing kidney dysfunction (e.g., people with diabetes, high blood pressure, or family history of kidney disease; people over sixty; and non-Hispanic blacks), might wish to forgo creatine, or otherwise take only the lowest effective dose (3 g/day)[527] after talking to their doctor.
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.

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]. 

Each serving of Optimum Nutrition Creatine supplies a full 5 grams (5000 mg) of 99.9% pure Creapure brand Creatine Monohydrate. The patented production method used to produce this Creatine yields a tasteless, odorless powder that mixes easily into water or juice and does not readily settle to the bottom. As a result, the gritty taste or texture you may have experienced with other Creatine powders is not associated with this product. Keep Reading »
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.
Negative regulators of the creatine transporter (CrT) are those that, when activated, reduce the activity of the CrT and overall creatine uptake into cells. As noted above, CrT activity is positively regulated by mTOR.[158] Consistent with the well-known role of AMPK as a suppressor mTOR signaling,[177] CrT activity has also been shown to be inhibited in response to AMPK activation in kidney epithelial cells.[178] Since AMPK suppresses mTOR via upstream TSC2 activation,[179] the negative regulation of AMPK on CrT activity in these cells appears to occur through an indirect mechanism. Although indirect, activation of AMPK has been noted to reduce the Vmax of the CrT without altering creatine binding, and is involved in internalizing the receptors.[178] This pathway seems to max out at around 30% suppression, with no combination of mTOR antagonists and AMPK inducers further suppressing creatine uptake.[178]
Trimethylglycine (TMG, betaine) is a dietary supplement and component of beet root, which is a methyl donor. It contributes to metabolic processes in the body which require a methyl group either directly (the methylation of homocysteine) or indirectly via replenishing the active form of folate or via replenishing S-adenosyl methionine (SAMe). As the synthesis of creatine (via GAMT) requires a donation from SAMe,[597] it is thought that TMG can aid in creatine synthesis, which has been noted in the rat liver in the absence of creatine supplementation.[598]
I bought this for my husband since he recently started lifting again. I knew that he wanted to gain as much muscle mass as possible and this looked like a pretty good product. It comes in a nice black bottle with good labeling. The bottle contains 90 capsules, which is about a month and a half worth of supplements. He has been taking 2 capsules before bed each night and for the past few weeks and has had no negative side effects. It's also really easy to remember since you take the both at the same time instead of spread throughout the day. He says that he has noticed a difference most of all in his muscle tone and just an overall feeling of being refreshed.

Spero Karas, MD, assistant professor of orthopaedics in the division of sports medicine at Emory University, says that testosterone, the male hormone responsible for muscle growth, maxes out between the ages of 16 and 18. It reaches a plateau during the 20s and then begins to decline. As a result, muscle building after the adolescent years can be challenging, he says.
In addition to the proper amount of sleep, do not overdo your training regimen. While you might be tempted to think that "more is better," in fact the opposite is true. You can reach a point known as "over-training", in which you'll lose the ability to "pump" (engorge the muscles with oxygen-rich blood) your muscles, and this can even lead to muscle wasting—exactly the opposite of what you are trying to achieve. Here are some symptoms to be aware of if you think you may be falling into the over-training zone:
This concept of timing has been applied to everything from fat burners, protein supplements, carbohydrates, and various other supplements. In some cases, you can see a difference based on when you take a product. But more often, the timing is based more on anecdotal evidence than any hard science. Recently, this nutrient timing aspect has even been extended to creatine, a product that is so effective that it’s worth the investigation of determining if there’s an element that can give you even greater benefits.
3) Relatively low cholesterol. This is one nutrition category that many people overlook with these supplements, but it's arguable one of the most important. Remember, if you're going to be downing 2 of these a day, you DON'T want to be maxing out your cholesterol intake. Luckily, this whey keeps it down to 30mg per scoop (which is about 10% of your daily intake). I've seen worse and ... full review
One study on 27 otherwise healthy men supplementing creatine (0.3g/kg loading for a week, 0.05g/kg thereafter for 8 weeks) with a thrice weekly exercise regiment noted that alongside greater increase in lean mass and power relative to placebo at 4 and 8 weeks, myostatin in serum decreased to a greater extent with creatine (around 17% at 8 weeks, derived from graph) than it did with placebo (approximately 7%).[356] Increases in GASP-1, a serum protein that inhibits the actions of myostatin by directly binding to it,[357] were not different between groups.[356]
I was building up, bulking, going after the mass, which to me meant 230 pounds of sheer body weight. At that time, I didn’t care about my waist or anything else that would give me a symmetrical look. I just wanted to build a gigantic 250-pound body by handling a lot of weight and blasting my muscles. My mind was into looking huge, into being awesome and powerful. I saw it working. My muscles began bursting out all over. And I knew I was on my way.”
I’m glad you found some good information from this article. For any of these supplements, I would suggest talking to your doctor and pharmacist. I would suggest thinking about why you are interested in taking testosterone. Are you looking to increase muscle size? Bulk up? Knowing your fitness goals will help you determine which products are appropriate for you.
It is possible that females could benefit more than males due to a combined lower creatine kinase activity as well as having altered purine metabolism during depression,[257] but no human comparative studies have been conducted yet. One rat study noted that creatine monohydrate at 2-4% of feed had 4% creatine able to exert anti-depressive and anxiolytic effects in female rats only.[228]
The first published results (not blinded) noted that a loading phase of 20g of creatine for a week, followed by 3g daily for up to six months, was able to enhance maximal voluntary isometric muscular contraction (MVIC) on a dynamometer for both the knee and elbow joints, with enhanced fatigue resistance on the same joints in more than half of subjects (53-70% response rate).[545]

These effects are secondary to creatine being a source of phosphate groups and acting as an energy reserve. The longer a cell has energy, the longer it can preserve the integrity of the cell membrane by preserving integrity of the Na+/K+-ATPase and Ca2+-ATPase enzymes.[241][235][236] Preserving ATP allows creatine to act via a nongenomic response (not requiring the nuclear DNA to transcribe anything), and appears to work secondary to MAPK and PI3K pathways.[226]

Every 4-8 weeks, vary your routine. As your body adapts to stress, you'll hit a plateau where the benefits of weight training will begin to diminish. The only way to prevent this from happening is to change things up, such as by increasing weight and changing exercises. Try a week of really piling the weights on, and do six to eight reps per set at the maximum weight you can manage with proper form. The more lifting experience you have, the more often you should vary your routine.
If you'’re looking to add muscle mass to your frame, hitting the weights hard is a given. Quality time in the gym begins a cascade of changes that will stimulate your muscles to grow bigger in response to the challenges you throw their way. It'’s tempting to think that'’s all it takes to add muscle to your body. After all, you can actually feel your biceps growing after an intense set of curls.
Take time to rest. To give your muscles time to recover, rest one full day between exercising each specific muscle group. You might choose to work the major muscle groups at a single session two or three times a week, or plan daily sessions for specific muscle groups. For example, on Monday work your arms and shoulders, on Tuesday work your legs, and so on.
For the bench press, start with a weight that you can lift comfortably. If you are a beginner, try lifting the bar along with 5lbs or 10lbs on each side. With arms at shoulder-width apart, grab onto the bar and slowly lower the bar until it's at nipple level; push up until your arms are fully extended upwards. Do 8–10 repetitions (reps) like this for three sets (3 x 8), adding additional weight each set. Once you have a few months of practice, slowly increase weight and go down to 6–8 reps per set, aiming to reach muscle failure at the end of the third set.
Athletic performance. Creatine seems to help improve rowing performance, jumping height, and soccer performance in athletes. But the effect of creatine on sprinting, cycling, or swimming performance varies. The mixed results may relate to the small sizes of the studies, the differences in creatine doses, and differences in test used to measure performance. Creatine does not seem to improve serving ability in tennis players.
“Imagine you've fasted for over eight hours,” he says. “At breakfast, you're firing your metabolism off really high. If you don't eat for another five hours, your metabolism starts to slow right down and you have to try and kickstart it again with your next meal. If you eat every two and a half to three hours, it's like chucking a log on a burning fire.”
If there are any benefits for swimming performance from creatine supplementation, they appear to be limited to a 50 meter sprint or a handful of 50 meter sprints with short intermissions. Excessive sprinting (over six sprints with short breaks) or too long of a break (five minutes rather than two) seem to not be associated with the benefits of creatine supplementation.
Ghost Size takes the cake for muscle growth. The key to this formula is epicatechin, an antioxidant found in chocolate and certain plants that is linked to a wide array of benefits. These include increased nitric oxide produciton, better oxygenation to the brain, and muscle growth: epicatechin appears to inhibit myostatin, which suppresses muscle growth, and the dosage found in Ghost Size is in line with studies that examined this effect.
Different forms of creatine in combination with other sports supplements as well as varying doses and supplementation methodology should continue to be researched in an attempt to understand further application of creatine to increase sports and exercise performance of varying disciplines. It is important to remain impartial when evaluating the safety of creatine ingested as a natural supplement. The available evidence indicates that creatine consumption is safe. This perception of safety cannot be guaranteed especially that of the long term safety of creatine supplementation and the various forms of creatine which are administered to different populations (athletes, sedentary, patient, active, young or elderly) throughout the globe.
In complex training, weight training is typically combined with plyometric exercises in an alternating sequence. Ideally, the weight lifting exercise and the plyometric exercise should move through similar ranges of movement i.e. a back squat at 85-95% 1RM followed by a vertical jump. An advantage of this form of training is that it allows the intense activation of the nervous system and increased muscle fibre recruitment from the weight lifting exercise to be utilized in the subsequent plyometric exercise; thereby improving the power with which it can be performed. Over a period of training, this may enhance the athlete's ability to apply power.[39] The plyometric exercise may be replaced with a sports specific action. The intention being to utilize the neural and muscular activation from the heavy lift in the sports specific action, in order to be able to perform it more powerfully. Over a period of training this may enhance the athlete's ability to perform that sports specific action more powerfully, without a precursory heavy lift being required.
Longer rest periods are more ideal for making progressive tension overload happen, and shorter rest periods are more ideal for generating metabolic fatigue. So, if you’re doing an exercise that is better suited for progressive overload (i.e. primary compound exercises), you’re going to want to rest longer between sets to maximize strength output. And if you’re doing an exercise that is better suited for metabolic fatigue (i.e. isolation exercises), you’re going to want to rest less between sets to make that happen. And if you’re doing an exercise that is suited equally for a combination of the two (i.e. secondary compound exercises), you’re usually going to want a moderate rest period somewhere in between.

In humans, studies that investigate links between serotonin and creatine supplementation find that 21 trained males, given creatine via 22.8g creatine monohydrate (20g creatine equivalent) with 35g glucose, relative to a placebo of 160g glucose, was found to reduce the perception of fatigue in hot endurance training, possibly secondary to serotonergic modulation, specifically attentuating the increase of serotonin seen with exercise (normally seen to hinder exercise capacity in the heat[233]) while possibly increasing dopaminergic activity (conversely seen to benefit activity in the heat[234]).[155] 

The creatine kinase system appears to be detectable in endothelial cells.[314][315] Under basal conditions, creatine itself is expressed at around 2.85+/-0.62μM[316] (three-fold higher than HUVEC cells[314]). When incubating the medium with 0.5mM creatine, endothelial cells can take up creatine via the creatine transporter (SLC6A8) and increase both creatine (almost doubling) and phosphocreatine (nearly 2.5-fold) concentrations.[316]
When it comes to building lean muscle, size bodybuilders are king. That’s their ultimate goal. Sure, Crossfit, powerlifting and all the other modalities will build muscle, but that’s not their focus. They want performance and any muscle they build is a side effect. Not so with bodybuilding where muscle size and shape are the priorities. Learning how to build muscle for the sake of building muscle has some benefits to the performance athlete. It allows for ais less injury prone. Its also a fact that bigger muscle contract harder regardless of technique or form, so it’s a good strategy to throw in some bodybuilder muscle building sessions here and there to give yourself stronger muscles to then train for performance. Build the muscle bigger, then train it to perform better.

It’s an amazing feeling when you graduate from lifting 10-pounders to 15-pounders. “Over time, you get better at something you’re doing, and you develop a sense of mastery and feeling that you’re getting stronger,” explains James Whitworth, a doctoral research fellow in the Biobehavioral Resistance Training Lab at Columbia’s Teachers College in New York City. “It helps your confidence, and that gives you a boost in self-esteem.”


Most of us have lives, or jobs, or school, or family, or whatever else that puts some kind of limit on when and how often we can work out. For example, are there certain days that you are able to work out on, and certain days you aren’t? Are you able to train 5 days per week, or would 3-4 be more ideal? Choosing a split that suits your personal schedule and is as convenient for you as possible will be crucial for adherence, and without adherence, nothing is going to work.
It is known that intracellular energy depletion (assessed by a depletion of ATP) stimulates AMPK activity in order to normalize the AMP:ATP ratio,[333][334] and when activated AMPK (active in states of low cellular energy[335] and colocalizes with creatine kinase in muscle tissue[336]) appears to inhibit creatine kinase via phosphorylation (preserving phosphocreatine stores but attenuating the rate that creatine buffers ATP). While phosphocreatine technically inhibits AMPK, this does not occur in the presence of creatine at a 2:1 ratio.[334] It seems that if the ratio of phosphocreatine:creatine increases (indicative of excess cellular energy status) that AMPK activity is then attenuated, since when a cell is in a high energy status, there is less AMP to directly activate AMPK.[334][336][337]
I know this goes against the recommendations you often see in stereotypical bodybuilding routines (i.e. the ones that involve having a single “chest day” or “arm day” or “shoulder day” once a week), but that’s just one of the many reasons why those types of routines suck for us natural, genetically-average people, and work best for steroid users with great genetics.

Caffeine is the naturally occurring alkaloid and stimulant in coffee, tea, cocoa, guarana, cola and other plant product beverages. A strong cup of brewed coffee will give you about 100 milligrams of caffeine, instant coffee around 80 milligrams, often less, and tea down around the 40 milligrams. It varies from product to product and how you prepare the drink.
A: Let your symptoms be your guide. A slight sore throat or runny nose may require you to back off for a day or two but don’t confine yourself to your bed and assume the worst. However, you must also remember that prolonged, intense exercise can decrease immune function and make you more susceptible to bacterial and viral based sickness so it's equally as important to listen to your body and respond accordingly.

However, the basis of “take creatine after your workout” comes from a 2013 study published in the JISSN, which can be found here (open access too!). In this study, recreational male bodybuilders (19 men overall) were given five grams of creatine either before or after their workouts. They trained five days per week but were also directed to consume 5g on their rest days at any time they wanted. The workouts were fairly similar to most gym workouts, and the methodology (what they did and how they did it) suggests that the findings would apply to most weightlifters.
Many trainees like to cycle between the two methods in order to prevent the body from adapting (maintaining a progressive overload), possibly emphasizing whichever method more suits their goals; typically, a bodybuilder will aim at sarcoplasmic hypertrophy most of the time but may change to a myofibrillar hypertrophy kind of training temporarily in order to move past a plateau. However, no real evidence has been provided to show that trainees ever reach this plateau, and rather was more of a hype created from "muscular confusion".[clarification needed][citation needed]

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.
