Proviron is really good addition in to TRT. I just finished 6 weeks in my HRT with addition of Proviron.
25mg per day is minimum. It depend how you respond on this stuff. But with 50mg per day you have all effect which it should does ( lower estradiol, higher DHT, raise free TST in your body,hardness).
Use 50mg per day and you will see good result. But Proviron can make really bad acne, it did cause much worst acne to me. Try to use Nizoral 2% shampoo on place were you get acne, if it's cause by DHT it will clear it up. If it's cause by higher Androgens ( Proviron is high Androgenic drug ), than, there's no help. (my problem )
