Proviron works as an effective anti-oestrogen in the aromatase inhibitor class. Though it falls short of Anastrozole on potency, this drug has stayed popular for decades. Its base is Mesterolone — a substance with a steroidal nature. In practice, Mesterolone is an altered form of dihydrotestosterone. That gives Proviron a strongly androgenic, moderately anabolic profile.
Proviron is best used directly on-cycle, to hold the aromatisation process in check. Women should not use Mesterolone for athletic purposes. In sports, it is intended for men only.
Effects of Proviron
Amongst the positive effects of the anti-oestrogen:
- Lifts muscle hardness;
- Suppresses aromatase activity — which slows the conversion of testosterone into female hormones;
- Raises sexual drive;
- Inhibits transport proteins and thereby raises the concentration of free testosterone in the blood.
Those qualities are what made the drug popular in sport. Proviron is a sensible pick for athletes planning a course with aromatising AAS. That category covers all testosterone-containing AAS and Metandienone.
Proviron Rules of Use
In amateur bodybuilding, Proviron is used strictly as an aromatase inhibitor. 50 mg daily is usually enough for a good result. If need be, the daily dose can go up to 100 mg.
In professional bodybuilding, Mesterolone sometimes shows up in the final preparations for competition. The reason is simple — it sharpens definition and brings up muscle hardness. For that purpose, Proviron is taken at 150 mg daily. Duration should be capped at three months. And it is worth remembering: Mesterolone is a strong androgen.
