I know Propecia and all those stop it on Testosterone but im not sure about on tren. Heard nothing stops it. But nizoral 2% shampoo if your not prone to mbp. Ive used tren a few times and been good so far but im on a higher dosage this time around and i think im suffering a bit of tren paranoia and anxiety about my hair even tho i got it cut a few weeks ago i was paranoid it was thinning but ive been assured many times its fine and just short. im using nizoral 2% and im pretty sure im alright but does propecia or any of those work with tren? Cheers.
