I am just pointing out potential risks. If you go into group buys for unapproved/investigational drugs and you think "the worst that can happen is I lose some money" then you are double-digit IQ. I am not advocating for or against participating in group buys, I just want my balding bros to educate themselves as best as possible so there's no regrets.
Looks like tested in 33 people so far. For instance, finasteride's side effect profile was reported to be ~2% or whatever so it's entirely possible those kinds of sides wouldn't appear in a trial with <50 people. Furthermore, median age of trial participants was 67.5y/o, even if they got the side effects that we're worried about, they may not really notice it. Anyway, you're one of the most knowledgeable people on the board so you know all this already, but you should recognise that even with your research/knowledge and the trial's results your conclusions about safety are still just conjecture until a trial comes out with more than a handful participants. Anyway, I hope you're right about all these treatments
