Provibol application in bodybuilding

Provibol in Sports
Many athletes do not seriously consider drugs that can not help build muscle mass. For this reason, they are convinced of the uselessness of Proviron in bodybuilding. However, its purpose is completely different, and the drug is very important for the health of athletes.

Provibol  is an androgen, oral DHT (dihydrotestosterone) steroid. The most common reason why athletes consider the possibility of including it in their course is anti-estrogenic activity. Before the use of anti-aromatase agents and SRME (selective estrogen receptor modulators), such as Clomid or Nolvadex, was the rationale for taking Provibol as an anti-estrogen. Proviron has a weak anti-estrogenic effect, and currently there are more effective drugs. When they are used, there is no need to take Provibol.

This is a strong enough anti-estrogen, which reduces the effect of aromatization of steroids. Due to this, the body does not accumulate liquid, it prevents the possibility of gynecomastia.


Also, to give muscle elasticity, the drug is used by women. However, at present Clenbuterol is more preferable for them, which does not cause virilization, unlike Provibol.

The mechanism by which Provibol has some efficacy lies in binding to the estrogen receptors without activation, and with the aromatase enzyme. In the first case, this partially reduces the number of receptor sites instantly available to bind estrogen, thereby reducing estrogenic activity. In the second case, some of the aromatase molecules are not available at any given time for binding and converting testosterone, they are connected with sites occupied by the placerolone.
