In , human studies dating back to were reviewed by a scientist named Hunter 1 , in these studies, subjects were "loading" with creatine up to 20 grams per day for 6 days. In , Chanutin 2 detailed case studies where human subjects loaded 4 times a day for 10 days.
In the 70's, researchers thought insulin might be involved in the uptake of creatine, this was determined yet again in by Harris 3. It wasn't until , however, that creatine monohydrate was actually introduced as a supplement by EAS, it was called Phosphagen. Since then it's pretty much taken the supplement world by storm and has proven to be one of the most effective supplements on the market. Muscles store creatine as creatine phosphate, which functions as part of the ATP-CP energy system, also called the Phosphagen system.
Muscle cells contain 4 to 6 times as much creatine phosphate as ATP. In fact, it can be said that skeletal muscle is a creatine requiring tissue. ATP is the immediate energy source for muscle cells at both high and low intensities, however, it can take less than a second to burn your bodies reserve of ATP. This is where creatine phosphate also called phosphocreatine comes in. Your body has a small reserve of creatine that your muscles can quickly convert to ATP.
However, this will only power an all-out effort for 3 to 15 seconds. As exercise intensity decreases and the duration increases, as in a marathon type race, your body turns to other systems of energy production. The Phosphagen system is used primarily for shorter duration exercise, as in bodybuilding training. Creatine use as a product that can enhance muscle cell energy production becomes obvious when you look at the re-synthesis of creatine. There's a regulating enzyme known as creatine kinase that breaks down creatine, separating the phosphate molecule from the creatine molecule.
So basically your body can "manufacture" fresh ATP through this process, which can take up to minutes. Don't many bodybuilding programs require at least a few minutes rest? So, what's the bottom line? Well, the more creatine available, the more that can ultimately be used for energy, allowing you to train harder and longer which, in turn, can lead to better results, be it improved performance, more muscle, more strength.
What else does it do? It acts as a "volumizer" or "cell expansion" product by pulling water into the muscle cell, causing it to expand, resulting in a increase in muscle size and strength. This is a big category right now, largely due to NO products, but creatine was really the first product to cause this effect.
Some say that this is temporary and you lose your size when you go off. To a point this is true, but it's also true for pretty much all aspects of bodybuilding, isn't it? If you cut back on protein, you risk losing size, when you go off your steroid or pro hormone cycle, you lose size, when you stop training, you lose size. You don't lose everything this is also true for all aspects of bodybuilding but you will lose something.
Regardless, most people will cycle creatine, taking week breaks. Without some of those informations we wouldn't be able to work properly. Most of the cookies are for statistical purposes, they give us an idea what parts of the website you like most and what parts you find difficult to use.

So I have an extremely fast metabolism and I have been talking to some people. Overall they said Amino Acid forumla would be the best for me. Can anyone explain what these do to you and your body and how they help in gaining strength and muscles.
Also I heard NO2 would be bad for me since it raises your metabolism and sinbce I already have a high one it would burn the protein powder I am taking. Also my brother tried to turn me off creatine. So what do the amino acid formula do for you and does it work as good as Creatine or NO2? Today's Top Stories.
How to Eat Like Chris Hemsworth. Many stores sell nitric oxide supplements, which claim to boost workout performance and enhance endurance. Nitric oxide is a naturally occurring gas in the body that helps increase blood flow. Nitric oxide supplements contain ingredients that are said to produce more nitric oxide in the body, thereby improving your workout.
But do they actually work? The research is mixed. What is nitric oxide? Subscribe to Men's Health. You may be able to find the same content in another format, or you may be able to find more information, at their web site.
