Does Proviron (Mesterolone) block estrogen

- Apr 08, 2020-

Proviron acts as a mild aromatase inhibitor so by that nature it has some estrogen block effect. It needs to be known though that you won’t find this estrogen blocking effect as strong as it is with true AI drugs like Arimidex, but it does come with great benefits for steroid users because increased estrogen is the cause of gyno and water retention, so Mesterolone can greatly help combat these, leading to increased muscle hardness with a low concentration of estrogen in the blood.
