I new this years ago. Way back in 1993 I used test C injectable stanazol(vet grade)with 25mg of proviron. After that I always used proviron when ever I could whilst on a course of anabolics. As a side not I have also used it on the back end of a cycle leading into pct and also bridged with it. Try not to take more then 50mg per day or you will turn into a masturbating freak. lol
