General information about Provibol in Belgium

Provibol (Proviron) is an orally acting synthetic androgen that does not have anabolic characteristics. Provibol is used in school medicine to alleviate or cure disorders facilitated by deficiency of male sex hormones. Many athletes, for this reason, often use Proviron at the end of a steroid treatment in order to increase the reduced production of testosterone. However, this is not a good idea because Provibol has no effect on the body's testosterone production, but – as mentioned at the beginning – reduces or completely eliminates the dysfunctions caused by testosterone deficiency.
These include impotence which is mainly caused by androgen deficiency which can occur after stopping steroids, and infertility which manifests in a reduced sperm count and reduced sperm quality. sperm. Proviron is therefore taken during steroid administration or after discontinuation of steroid use, to rule out possible impotence or reduced sexual interest. This, however, does not contribute to the maintenance of strength and muscle mass after treatment. There are other compounds better suited for this (see HCG and Clomid). For this reason Provibol is unfortunately cunsidered by many to be a useless and useless compound.

Provibol Features in Belgium

Provibol is also an estrogen antagonist which prevents the aromatization of steroids. Unlike the antistrogen Tamoxifen which only blocks estrogen receptors (see tamoxifen) Proviron already prevents the aromatization of steroids.Therefore, gynecomastia and increased water retention are successfully blocked. Since Provibol strongly suppresses the formation of estrogen, no rebound effect occurs after discontinuation of the use of the compound as is the case for example with tamoxifen where an aromatization of steroids is not prevented. It can be said that tamoxifen cures the problem of aromatization at its root while tamoxifen just cures the symptoms. For this reason, male athletes should prefer Proviron over Tamoxifen.

With Proviron the athlete gets more muscle hardness since the androgen level is increased and the estrogen concentration remains low. This is especially noted positively when preparing for a competition when used in combination with diet. Female athletes who naturally have higher estrogen levels often supplement their steroid intake with Proviron, resulting in increased muscle hardness. In the past, it was common for bodybuilders to take a daily dose of one 25mg tablet over several weeks, sometimes even months, in order to appear hard all year round.


This was especially important for athlete appearances at guest shows, seminars and photo shoots. Since Proviron is very effective male athletes usually only need 50mg/day which means the athlete usually takes one 25mg tablet in the morning and another 25mg tablet in the evening. In some cases, one 25 mg tablet per day is sufficient. When you combine Proviron with Tamoxifen (50mg Proviron/day and 20mg Tamoxifen/day), it will lead to almost complete suppression of estrogen.
