Bro, proviron is awesome. I use it on all my cycles. As far as using it for PCT its a waste. It will not bring your natty test levels. Proviron is a steroid, and will keep you shut down. Some say proviron has no effect on the HTPA, but go look at the blood test results on OLM after a PCT with proviron. Not positive that it hindered the result, but it definitely did not help. As far as running it as an estrogen it will only work if your running low doses, or are not prone to estrogen sides. It will dry you out a bit, but will not replace the benefits of a good AI.
