Proviron is NOT for getting gains. It will harden you up a bit. Gives you a libido boast. It ups your test level WITHOUT interfering with your HPTA. So when on roids and sex drive is low, this is a good drug to keep your thing going.
It also fights estrogen. I had to take it when on Sustanon to avoid upcoming gyno.
As for sides: it works heavy on your prostate. No big deal for young guys, but trust me you will get older and will get those problems.
Proviron alters your prostate in a very serious way. Only healthy people should take this drug. One cancer cell in your prostate while taking Proviron and this will multiply like rabbits.
The little addy says max 3x50 mgr a day.
Another side: when taking 3 a day changes are you cannot keep him down......
