Did that with anabolics.
Do a controled study of two groups of people with similar genetics.. Have one take all these supplements, the others just good old chicken, rice and gnc whey.. Same training and caloric intake..
They'll look pretty much same after 5 months or so.
Good assumption...would be interesting to see this study done.
Like you said, take two individuals with similar genetic profiles, put them on a similar diet and training regimen. Give one the supplements and the other his diet and whey or something and after a few months see how much different they actually look from each other.
Would never happen though as supplements are basically the reason there are any bodybuilding mags whatsoever
