Proviron has anti-estrogenic properties, boosts free testosterone and provides a nice cosmetic look to your muscles. The biggest benefit of proviron is that it increases free testosterone. Essentially, what this dose is make the steroids you stack with it even more effective. It's a great compound to incorporate into a pre contest or cutting cycle. It is very anti-catabolic.
For my competition March 19th, I am planning on doing a 6 week pre contest cycle of:
anavar 40mg/day
proviron 25mg/day
primo 25mg/day
Along with my TRT dosage of 150mg test c per week + 10mg aromasin EOD.
As a stand alone compound, it won't do much. You also still need to use an AI with whatever cycle you incorporate it with. I recommend aromasin 10mg EOD.
