In October 1994, the Dietary Supplement Health and Education Act (DSHEA) was signed into law in the USA. Under DSHEA, responsibility for determining the safety of the dietary supplements changed from government to the manufacturer and supplements no longer required approval from the U.S. Food and Drug Administration (FDA) before distributing product. Since that time manufacturers did not have to provide FDA with the evidence to substantiate safety or effectiveness unless a new dietary ingredient was added. It is widely believed that the 1994 DSHEA further consolidated the position of the supplement industry and lead to additional product sales.[6]
It’s important to remember that since everybody is different, these estimates are just that. How the numbers work out for each person will definitely vary. So many factors—like genetics, hormones, sleep, and diet—can change the rate at which our bodies burn calories. And some people may have a harder time than others when it comes losing fat or gaining muscle—again, there are so many factors at play and our body chemistries are all different. Strength training is important for many, many, many other reasons (more on that later), but if you’re looking to increase your metabolism, it’s important to have realistic expectations and know that strength training can make a difference, but probably won’t drastically affect how many calories you burn from one day to the next.
Unfortunately, many people haven't gotten the message that strong is in. Indeed, statistics on strength training are grim: According to the Centers for Disease Control and Prevention (CDC), less than 30 percent of American adults engage in muscle-strengthening activities like lifting weights or doing push-ups at least twice a week—the recommendations set out by the government. 
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.

Post workout, it’s important to restore your body’s energy by consuming protein and carbs. When you’re trying to build muscle, this is an especially important step. Protein powder is a great muscle builder for your post-workout routine, as long as you include a carbohydrate as well. You can get this by eating a banana or adding oats or banana to your protein shake. Or simply cook up a batch of healthy oatmeal muffins and include protein powder in your recipe. Then, enjoy your post-workout supplement as a delicious snack!
“There is a lot of mixed research on creatine’s ability to improve muscle strength,” the government website says. “However, analyses of this research show that creatine seems to modestly improve upper body strength and lower body strength in both younger and older adults.” Creatine has also been shown to improve athletes’ performance in rowing, soccer, and jumping height.
Most typical bodybuilding programs have way too many sets and reps and use the wrong exercises. However, if you lower the total volume, go heavier, and use compound movements as I’ve outlined above, there is nothing wrong with a body-part split for advanced lifters. In fact, it’s often less stressful to the joints than your average upper/lower split.

Most folks work a 9 to 5 position but if you’re not in the corporate world yet then odds are you’re a student with classes scattered throughout the day and it takes up the vast portion of your free time. That being said, you’re likely going to have to work out in the morning or the evening in order to fit in your session amidst the hectic commitments in your everyday life. Here are a few things to consider in regards to each time period:
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.
For example, say you are pursuing a muscle power objective in which you have decided to perform 3 sets of 8 repetitions each. You'll want to make sure you don't add too much weight so that you are able to perform all 8 repetitions before your muscles are too tired to finish the set. Conversely you'll want to make sure you add enough weight so that you are not simply breezing past the repetitions and finish your sets of plenty of energy still left in the tank. While it may take a few workout sessions to find the right combination, once you'll do it'll be easy to monitor and increase weight as you progress.

You see, there is only so much muscle that the human body is capable of building in a given period of time. So, if you supply your body with MORE calories than it’s actually capable of putting towards the process of building new muscle… it’s not going to magically lead to additional muscle being built. It’s just going to lead to additional fat being gained.
MuscleTech Cell-Tech is the best creatine stack. A lot of products claim to be more effective than regular monohydrate and while that’s seldom true, Cell-Tech has the goods. It combines creatine with a big 38 grams of carbohydrates and some alpha-lipolic acid, and some studies actually show that this trifecta could be more effective at sending creatine to the muscles than plain creatine.

Glutamine and beta-alanine are amino acids and HMB, beta-hydroxy-beta-methyl butyrate, is a byproduct of leucine, another amino acid. Promoting individual amino acids, the building blocks of protein, to enhance performance in the strength sports has been a particular focus of supplement manufacturers over the years. To date, the evidence for any advantage has been mixed and mostly unimpressive.


In the early 2000s, the IFBB was attempting to make bodybuilding an Olympic sport. It obtained full IOC membership in 2000 and was attempting to get approved as a demonstration event at the Olympics, which would hopefully lead to it being added as a full contest. This did not happen and Olympic recognition for bodybuilding remains controversial since many argue that bodybuilding is not a sport.[11]
In isolated striatal cells (expressing creatine kinase), seven day incubation of 5mM creatine (maximal effective dose) appears to increase the density of GABAergic neurons and DARPP-32 (biomarker for spiny neurons[225]) with only a minor overall trend for all cells[226] and showed increased GABA uptake into these cells, as well as providing protection against oxygen and glucose deprivation.[226]
Listen, I know in the beginning of this post I was sympathetic to your problem, but I am also here to say, Suck It Up. I can tell you that to gain weight, you need to focus on making your meals a habit rather than an afterthought. Your body is pre-programmed with your genetic disposition. And in your case, you have a very fast metabolism that digests and burns calories quickly. Focus on having 5-6 calorie-dense meals a day spaced 2-3 hours apart so that your body is constantly being provided with something to metabolize and build muscle.
Finally, starvation (nutrient deprivation for four days) appears to increase activity of the creatine transporter secondary to decreasing serine phosphorylation (SGK target)[173] with no influence on tyrosine phosphorylation (c-Src target).[173] Starvation-induced increases in creatine influx do not necessarily mean more phosphocreatine, however, due to a depleted cellular energy state.[173]
A typical creatine supplementation protocol consists of a loading phase of 20 g CM/d or 0.3 g CM/kg/d split into 4 daily intakes of 5 g each, followed by a maintenance phase of 3-5 g CM/d or 0.03 g CM/kg/d for the duration of the supplementation period [5]. Other supplementation protocols are also used such as a daily single dose of around 3 – 6 g or between 0.03 to 0.1 g/kg/d [15,55] however this method takes longer (between 21 to 28 days) to produce ergogenic effects [5]. Sale et al [56] found that a moderate protocol consisting of 20 g CM taken in 1g doses (evenly ingested at 30-min intervals) for 5 days resulted in reduced urinary creatine and methylamine excretion, leading to an estimated increase in whole body retention of creatine (+13%) when compared with a typical loading supplementation protocol of 4 x 5 g/d during 5 days (evenly ingested at 3 hour intervals). This enhancement in creatine retention would lead to a significantly higher weight gain when people follow a moderate protocol ingestion of several doses of small amounts of CM evenly spread along the day.

Now, while all three are definitely beneficial to the process, I’d consider metabolic stress and muscular damage to be of secondary and tertiary importance, respectively. In addition, they are also things that will pretty much take care of themselves when implementing the workout guidelines and recommendations we’ve already covered (namely for volume, rep ranges, rest periods and exercise selection).


It can be hard to know where to start when beginning strength training. There are countless exercises you can do, some of which work some muscles, but not others. There are safety concerns to beware of, a wide variety of sometimes confusing equipment to help you in your efforts, and so on. With some familiarity of the basics of getting started with strength training, actually doing so can become far less daunting, and you can begin to craft a routine that is targeted toward helping you achieve your personal goals.

Creatine is only taken up by its transporter, and changes in the activity level of this transporter are wholly causative of changes in creatine uptake. The transporter is regulated by mostly cytosolic factors as well as some external factors that affect creatine transport activity, [143] including extracellular creatine.[140] Agents affecting creatine transport are further divided into positive regulators (those that increase activity of the transporter) and negative regulators (those that suppress activity).

Side-Effects: While the signs of a great body may make one think that there cannot be anything wrong with bodybuilding supplements, the facts speak otherwise. Bodybuilding supplements do have side-effects and you must listen to your trainer before giving in to the thoughts of buying one. Creatine can cause heart problems, kidney problems, dehydration, diarrhoea and muscle cramping. You must also discuss your medical history with the trainer. 

In addition to the HIIT sessions, it’s always a good idea to go for a 30–60-minute walk as many days per week as you can. I recommend getting a minimum of 10,000 steps every day. Use a phone app to track them. If you’re into jogging, swimming, hiking, or some other form of long-duration, fairly low-intensity cardio, that is fine to do as well, and as often as you like.
It's woooooorkkkkkiiiinnnngggg!!! I've been working out without creatine for over a year and a half now and have been missing that extra boost at the end of a set of reps. Not anymore! Started to feel the creatine help out in my 4th workout since using this stuff. It's good, real good. Creatine is one of those only supplements that have actually been proven to increase strength and bursts of endurance at the end of a set, and it's that one thing that can turn a regular workout into something that you're proud of. Just buy it, it works, you won't be disappointed. Use 2 of their servings sizes though, you need 5mg not 2.5. No spoon in bag, you'll need a measuring cup. Mixes effortlessly in juice.

A child’s ability to regenerate high energy phosphates during high intensity exercise is less than that of an adult. Due to this, creatine supplementation may benefit the rate and use of creatine phosphate and ATP rephosporylation. However, performance in short duration high-intensity exercise can be improved through training therefore supplementation may not be necessary [54].
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.
Studies of so-called "smart drugs" have also been taken out of context. Some "smart" nutrients, available over the counter, are marketed as a way to "increase mental focus and concentration during training." The problem is that the studies they're based upon involved either animals or people with brain pathology. In normal people the effects of smart drugs remain unproven, except anecdotally.

Translation: your muscles are going to have more energy. The process of accessing that energy is so complicated, you almost need an organic chemistry degree to totally understand it. Yes, it’s complicated, but completely necessary for biochemical reactions like muscle contractions. And the more your muscle works, the more ATP is depleted and needs to be replaced for you to make progress toward your goals. With creatine supplementation, you can enhance your ATP regeneration and thus delay onset of muscle fatigue and work more intensely for a longer period of time. Little goes a long way in the pursuit of muscle gains.


The creatine kinase (CK) enzyme in rat heart tissue appears to have a KM around 6mM of creatine as substrate.[280] and is known to positively influence mitochondrial function as higher cytoplasmic phosphocreatine concentrations (not so much creatine per se) increase the oxidative efficiency of mitochondria[280] This is thought to be due to the transfer of high energy phosphate groups.[280]
In young rats given creatine in the diet at 2% of the diet for eight weeks, supplementation appears to increase bone mineral density (BMD) in the lumbar spine with a nonsignificant trend to increase BMD in the femur.[426] Despite the trend, the femur appeared to be 12.3% more resistant to snapping from mechanical stress associated with increased thickness.[426] Menopausal rats (ovarectomized) experience similar benefits, as supplementation of creatine (300mg/kg) for eight weeks during ovarectomy is able to increase phosphorus content of the bone and other biomarkers of bone health, although bone stress resistance was not tested.[427]
In muscle cells, the creatine transporter is predominantly localized to the sarcolemmal membrane. Western blot analysis of creatine transporter expression revealed the presence of two distinc protein bands, migrating at 55kDa and 70kDa on reducing SDS-PAGE gels.[147][148] The 73kDa band has been reported to be the predominant band in humans, with no differences based on gender.[148] A more recent report demonstrated that the 55kDa creatine transporter variant is glycosylated, forming the 73 kDa protein. Therefore, the 55 and 75kDa protein bands are actually immature and mature/processed forms of the creatine transporter protein, respectively.[149]
If you have been diagnosed with a certain testosterone deficiency, ask your doctor and/or pharmacist to see if TestoFuel could be beneficial for you. Aside from balancing your testosterone, you may experience increased muscle strength while using this supplement during your intense exercise routine. Here are certain instances where TestoFuel could help correct your testosterone problems:
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.
Supplementation of a loading phase of creatine has been noted to augment the increase in RBC levels of superoxide dismutase (SOD) from exercise, when measured immediately after, by 8.1%, but control groups increased to match within an hour.[299] Glutathione (normally decreases with exercise) and catalase (increases) were both unaffected,[299] and elsewhere in vitro red blood cells incubated with 3mM of creatine (within the supplemental range) is able to improve filterability (a measure of cell rheology, or fluid structure of the cell[300]) when RBC creatine was increased by 12.3% to reach 554µM.[301] This was thought to be due to reduced oxidative stress (assessed via MDA) in the red blood cells, which in the presence of 1-5mM creatine was progressively reduced by 20-41%.[301]

The specific mechanism of intestinal uptake for creatine is not clear, although transporters have been identified in rat jujenum, and confirmed at the mRNA level in humans.[129][130] The observation that creatine can be absorbed against a concentration gradient to a max ratio of 8:1 (8 times more creatine in the intestinal cell post absorption, relative to the lumen) supports transporter-mediated uptake, and the dependence on sodium and chloride implicate SLC6A8 (Creatine Transporter 1) as the operative transporter.[102]
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]

The winner of the annual IFBB Mr. Olympia contest is generally recognized as the world's top male professional bodybuilder. The winner of the Women's Physique portion of the competition is widely regarded as the world's top female professional bodybuilder. The title is currently held by Juliana Malacarne, who has won every year since 2014. Since 1950, the NABBA Universe Championships have been considered the top amateur bodybuilding contests, with notable winners such as Reg Park, Lee Priest, Steve Reeves, and Arnold Schwarzenegger. Winners generally go on to become professional athletes.
While I’m not well-versed in DNP, it is important to note that most supplements are not regulated by the FDA. The FDA has minimal standards for governing supplements before they make it to the shelves. All supplementation should be a case-by-case basis and under the discretion of a doctor and/or registered dietitian who knows your personal needs. Also, if you are consuming a well-rounded, healthy diet, supplementation may not be needed, even for making gains at the gym.

What happened was that, statistically speaking (less than 5% chance what was observed was due to chance means ‘significant’ for this study) there was no significant difference between pre- and post- workout, meaning that both were equally effective. This protocol did note that both groups found benefits with creatine supplementation, but they both found the same amount of benefit.
There is a great amount of research published on creatine supplementation; protocols of administration, forms of creatine, as well as potential side effects. Despite this, the mechanisms by which creatine acts in the human body to improve physical and cognitive performance are still not clear. The main objectives of this review are to analyze the more recent findings on the effects and mechanisms of creatine supplementation in sports and health. As a secondary purpose, we will analyze the most recommended protocols of ingestion and its potential side effects.
Vegetarians and other people who have lower total creatine levels when they start taking creatine supplements seem to get more benefit than people who start with a higher level of creatine. Skeletal muscle will only hold a certain amount of creatine; adding more won't raise levels any more. This "saturation point" is usually reached within the first few days of taking a "loading dose."

I get it. Bodybuilding is a subjective sport with judges that determine who wins based on the judges opinions. In the other resistance training sports you win objectively by outperforming your competitors. Bodybuilders also tend to work out differently with little concern for the weight being lifted, so long as the end result is a better-looking body. This can make bodybuilding type training seem narcissistic and shallow. That’s too bad because hard core resistance training athletes can learn a LOT from bodybuilders and how they train.
Product reviews – Since the effectiveness of products varies based on a wide number of factors, one of the best things to do is read creatine product reviews. The best rated creatine products will have consistently good reviews, meaning a lot of people use that product and would recommend it. However – remember to take reviews with a grain of salt, as there’s a lot of ignorance and misinformation out there.
Without supplementation, creatine is formed primarily in the liver, with minor contributions from the pancreas and kidneys. The two amino acids, glycine and arginine, combine via the enzyme Arginine:Glycine amidinotransferase (AGAT) to form ornithine and guanidoacetate. This is the first of two steps in creatine synthesis, and although rare, any deficiency of this enzyme can result in mild mental retardation and muscular weakness.[28] AGAT is also the primary regulatory step, and an excess of dietary creatine can suppress activity of AGAT to reduce creatine synthesis[29] by reducing AGAT mRNA levels, rather than resulting in competitive inhibition.[30]

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.
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.
