You know, I've spoken to few PhD's in biochem and endocrynology who work w/ aas in their studies. They can indeed tell lotsa genereal things as well as draw you fancy formulas for the structure of the substance, but none of them was able to advise on optimal use in sports as to max gains and min risks. On the other hand, knowledgeble bbers who have had decades of experiecnces (good and bad) can prolly share tips w/ you that no PhD will tell.
And its not really surprising. Theory is one thing, practice is another. I got a major in commerce and a masters in economics. We had very knowledgeble proffessors and instructors, who tought us fancy tricks about business and so, yet none of them ever were, nor most likely ever will be succesfull businessmen.
Heard of the phrase: those who can't do teach? I'm beginning to believe it more every day. Yes, there are exceptions, but exceptions only reinforce the rule.
