.. same question was asked but never answered.
I ran this compound myself and noticed the effects many describe from proviron ( very fast acting time, noticable sex drive increase, water retention, aggression )
Ingredient of the PH: 17-Beta-Hydoxy-Androstan-4-One
Ingredient of proviron: 1 alpha-methyl-17 Beta-Hydroxy-5 alpha-androstan-3-one.
Any thoughts on wether proviron could be an ingredient in this prohormone (trenbomb) ?
