I have been doing research on muscle building and have done some very specific testing. I have looked at over 50 studies and I have found most of these products do NOT work. The main reasons why are: the results of the studies don't match the claims, or the ingredients are very difficult to find in the stores or the Internet. There are also studies that prove the product doesn't work and are not based on real world results. I also looked at some products that claims they work and the results were not what you would think. I'm just a medical doctor who has reviewed a few products that have proven to be ineffective. I'm not a medical doctor and don't advise you to take a product unless you understand the risks, the symptoms, and the long term side effects. I'm just trying to make you aware of the possibilities that you are not aware of. If you're interested, I've made a list of some of the most common muscle building supplements.
1. Creatine The benefits of creatine supplementation are very well documented. A 2006 review found that creatine supplementation increased strength, body composition, and power output for both men and women. This study was done in humans and not animals.
