I used proviron at 50mg daily for a total of 6 weeks towards the end of my cycle, right up until the start of PCT. Dose was split in two, taken morning and night. My libido sky rocketed, I had a great sense of well being and that needed boost of energy. It dried me out a little, and my muscles were slightly hardened by the effects. The only sides I encountered were increased oily skin. Based on my past experiences with Proviron, I would say Alpha Pharma Proviron is definitely up there with the likes of Bayer Proviron. Great value for money.
