So you want all of us here to believe that pros use very little of anything so that they don't spill over.I guess you have not seen the thread about IFBB pros off drugs? wow man you really do think most here are stupid.
Most aren't stupid..just ill-informed or naive.
Pro's (for the most part) have the one thing (other than the norm of drive, determination, etc) thats separates them from the pack....genetics. Genetics includes response to gear...you'll notice almost all pro's look pretty damn good at an early age, BEFORE the took anything...response to gear, response to training.
I know many more amateurs that took boatloads of drugs, who never made it past the novice/ local level, despite having access to all the same...
