Leaks from participants in the phase 2 clinical trial is laughable "proof". The participants had no idea whether or not they had placebo treatment.
As for the supposed results of the group buy, why is no one actually coming forward with their experience? At this point, the only evidence of a failed group buy is you reporting on a youtube comment which says that other people tried it... Hardly a trustworthy evidence source. You don't have to convince us if you don' want, but what's the point of posting this then? Literally just spreading negativity for nothing.
I'm not saying pyrilutamide will work, but your comments have a 50% chance of being completely made up.
