Many of the products on this page are proven to work, but don't work well. So I am not recommending those products, and I am NOT listing supplements that don't work well. I have tried to list the products with at least a 0% success rate.
In general, I don't think it is worth the trouble or money to try to build muscle from supplements. It does not help your diet, or build muscle in a natural way. In this section, I will be talking about what supplements are likely to work, and what supplements might be just plain wrong. The idea of building muscle from supplements is to get enough protein to build up the muscles that are naturally your own, without eating any extra calories. So if you have a diet that is too low in fat, you will get a smaller gain in muscle mass. If you are already bulking, you will only be able to gain a little muscle, because you need more protein to build the muscle. If you are just training to lose weight, then you don't need any additional supplements for the protein. Some of these supplements have a really high fat content, but they might help you gain fat as well as build muscle. That is the real point of this page.
