I dunno if these are useful bodybuilding drugs but ghb may be of some benefit. It induces deep sleep and raises hgh levels. I have also read that it increases cortisol levels though. I don't think it's that useful in bodybuilding. Cocaine and Amphetamines like crystal meth, aderol, ritalin, dexadrine, etc. could theoretically be used to raise metabolism and curb appettite and provide energy for aggressive workouts, but I think they would be more catabolic than it is worth. Hmmm,,,what else? maybe marijuana could be used to increase appettite to aid in bulking during a cycle,,,lol. I personally however do not think that rec drugs mix well with bodybuilding.
