yes i work out, and i also do mma. i was wondering what are the best supplements for strength(legal). i want something that would still keep your strength even after you stop using it. nothing like creatine where the muscle is just water. something that gives you strength not just for a short period of time but also long term. im taking whey right now. i dont care much about muscle mass or size etc. (but it would be good) i care the most about STRENGTH
im 17 years old and im starting the p90x.
