Honestly, I think I'll stick with compounds that have been sufficiently studied for their safety and efficacy. Even if they aren't the most ideal compounds for gaining muscle, a body of literature exists that details the affects on the body. I design complex systems for a Pharmaceutical, I know the rigors of having adequate testing and research.
Supplement companies offering these new compounds? Great, thats awesome, keep it up - but they'll never understand the efforts a Pharmaceutical goes through to release a drug to market, nor will they ever understand all the affects of the drugs on the body. They are not appropriately staffed for such measures.
