I nearly posted my thoughts on the idea from the op at first but I got sidetracked. I did state that I was obviously not claiming trest was to common steroids as steroids are to natural, but I suppose I should have been more clear on that. The 5x contention (what the op originally asked about to be fair) does seem to strain credulity. But I
suppose it could be technically correct in some fashion. Perhaps in regards to binding affinity or another metric.
@Type-IIx can probably speak to that better than I can. But 5x as effective at building muscle tissue? I do agree that certainly does not seem to be born out by anecdotes. And that contention for dhb (in terms of building muscle) seems kinda ludicrous on its face.
But the main point of my post (that you were dismissing it because you don't know pros or others that have used it to great effect) still stands. That kind of rational is a common kind of logical fallacy, and that's why I stated it was not restricted to only aas/drugs. And that certainly seemed the main point you were contending. However, if you were merely taking issue with the 5x claim by Chevaz and others, then I do agree the burden of proof would be on he and others. Incredible claims require incredible evidence. Not that he would offer any beyond his own word lol.
