Proviron. Active: Mesterolone


Mesterolone is a synthetic, orally effective androgen which does not have any anabolic characteristics. In the school of medicine Mesterolone is used  to ease or cure disturbances caused by a deficiency of male sex hormones. Many athletes believe that using Proviron at the end of a steroid cycle  will increase testosterone production. This, however, is not a good idea since Mesterolone has no effect on the body’s own testosterone production but, as mentioned in the beginning, only reduces or completely eliminates the dysfunctions caused by the testosterone deficiency.

These are, in particular, impotence which is mostly caused by an androgen deficiency that can occur after the discontinuance of steroids, and infertility which manifests itself in a reduced sperm count and a reduced sperm quality. Mesterolone is therefore taken during a steroid administration or after discontinuing the use of the steroids, to eliminate a possible impotency or a reduced sexual interest. This, however, does not contribute to the maintenance of strength and muscle mass after the treatment. There are other better suited compounds for this (see HCG, Clomid). For this reason Mesterolone is unfortunately considered by many to be a useless and unnecessary compound. (Daniel Duchaine Underground Steroid Handbook 2: “I can think of no legitimate use for Mesterolone in enhancing athletic performance.”)

Uses in Bodybuilding

Most, however, do not know the main use of Mesterolone in bodybuilding. You should be aware that Mesterolone is also an estrogen antagonist which prevents the aromatization of steroids. Unlike the anti-estrogen Nolvadex which only blocks the estrogen receptors (see Nolvadex) Mesterolone already prevents the aromatizing of steroids. Gynecomastia and increased water retention are successfully blocked. Mesterolone strongly suppresses the forming of estrogens and no rebound effect occurs after discontinuation as case with Nolvadex for example, where an aromatization of the steroids is not prevented. One can say that Mesterolone cures the problem of aromatization at its root while Nolvadex simply cures the symptoms. For this reason male athletes should prefer Proviron to Nolvadex.

Because the androgen level is increased and the estrogen concentration more muscle hardness is obtained by the athlete. This, in particular, is noted positively during the preparation for a competition when used in combination with a diet. Female athletes who naturally have a higher estrogen level often supplement their steroid intake with Proviron resulting in an increased muscle hardness.


In the past it was common for bodybuilders to take a daily dose of one 25 mg tablet over several weeks, sometimes even months, in order to appear hard all year round. This was especially important for athletes making appearances at guest performances, seminars and photo sessions. Today Clenbuterol is usually taken over the entire year since possible virilization symptoms cannot occur which is not yet the case with Proviron.

Since Proviron is very effective, male athletes usually need only 50mg/day which means that 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 combining Proviron with Nolvadex (50 mg Proviron/day and 20 mg Nolvadex/day) this will lead to an almost complete suppression of estrogen.

Side Effects

Side effects in men are low at a dosage of 2-3 tablets/day. Proviron can be used with comparatively low risk in combination  with steroids. Even over several weeks. Since Proviron is well tolerated by the liver dysfunction do not occur in the given dosages. Athletes who believe ”more is better” could experience a paradoxical effect. The German manufacturer, Jenapharm, writes about its compound Vistimon in the package insert:

”In high-dosage treatments an occasional retention of electrolytes and water, and edemas (accumulation of excessive water in tissues) can occur.”

Those taking less than 2-4 tablets daily do not have to worry about this. The most common side effect of Proviron, or in this case, secondary symptom, is in part a distinct sexual over-stimulation and in some cases continuous penis erection. This condition can be painful and lead to possible damage. Lowering the dose or discontinuing the compound are the only sensible solutions.

Female athletes should use Proviron with caution. The possibility of androgenic side effects cannot be excluded. Women who want to give Proviron a try should not take more than one 25 mg tablet per day. Higher dosages and periods of intake of more than four weeks considerably increase the risk of virilization symptoms. Female athletes who have no difficulties with Proviron obtain good results with 25 mg Proviron/day and 20 mg Nolvadex/day.  In combination with a diet, report an accelerated fat breakdown and continuously harder muscles.
