I just take 50 mgs of Proviron daily, every morning. All in one dose. I dont know if 25 mgs will do anything, everything I have read on proviron is that 50mgs is usually the sweat spot on this. I am on Test C @ 300 mgs (weekly), Mast E @ 400mgs (weekly) and Proviron 50 mgs (daily). Feel great on this dose, mood is happy and stable, no really aggression (only in the gym).
