The most popular is creatine, but there are others like L-glutamine, Taurine, and more. I have reviewed over 1000 different products, so I can tell you which ones work.
Here are my thoughts on the supplements you need to buy. Please remember that I am not a health professional. Always do your own research and decide what works for you and your body. Creatine Creatine is a naturally occurring substance that is made by animals and humans. It is made from the amino acid l-histidine and is absorbed into the blood and used to build muscles. Creatine works very well in the short term for building muscle. But there are also problems with getting enough of it. You have to be careful to not overdo it in the beginning or else you could get a condition called "DHEA Overload Syndrome" (see here). DHEA is also a hormone that stimulates the production of energy and can affect your sleep. You can get this condition from a lot of other things such as drinking alcohol, taking prescription drugs, or being anorexic. However, DHEA Overload Syndrome is the most common problem that occurs when people go over their DHEA targets.
