Proviron – synthetic, orally acting androgen, doesn’t have anabolic features. In usual medicine Proviron is used for treating dysfunctions caused by insufficience of male sexual hormones. That is why many athletes use it at the end of the steroidal course in order to increase the secretion of decreased testosterone secretion. And it is not a bad idea: Proviron doesn’t affect the own secretion of testosterone but, as it is stated, softens and totally eliminates the dysfunctions caused by insufficient amounts of testosterone. Especially impotencies caused by dysfunctions due to insufficient amount of testosterone, which may come when the use of steroids is stopped or infertility that is expressed in decreased amount of sperm and its decreased quality. That’s why Proviron may increase the decreased sexual interest and possible potency during or at the end of the steroidal course. But the strength and mass, that disappear after the steroidal course, is not kept. Special preparations are used for this (see HCG, Dinerik and Fludestrin). That’s why Proviron is inspected by many, unfortunately, as an helpless excessive preparation (Daniel Dachain, „Underground steroid, vol. 2”): „I don’t see benefit from Proviron if we talk about sprots achievements”), because majority don’t know the main application domain of the preparation in bodybuilding.

Because Provimed is also an antagonist of estrogens, that prevents aromatization of steroids. Unlike Nolvadex antiestrogen, which blocks estrogen receptors (see Nolvadex), Proviron interferes the aromatization of steroids. Thus, gynecomastia and excessive water accumulation are prevented. Because Proviron strongly suppresses estrogen appearance, reverse effect doesn’t take place when it is no longer used, as it may happen at Nolvadex where steroidal aromatization is not prevented. It may be said that Proviron takes out the complaint (aromatization) completely, at the same time Nolvadex fights only the symptoms. Male athletes should prefer Proviron to Nolvadex. A better toughness will be achieved thanks to Proviron, since the level of androgens is increased and estrogen concentration is kept low. This is especially observed during the preparation to championship when combined with diet. The female athletes that naturally have higher level of estroegens, often add Proviron to steroids and this is reflected in the increased density of the muscles. It was a usual situation when the female professional athletes used 25 mg, i.e. 1 25 mg tablet daily during some weeks or even months in order to look slabsided during the entire year. This is especially important when we talk about presentation and shooting. Today Clenbuterol is often used during the entire year because it doesn’t cause virilization that are possible with Proviron. Since Proviron is very effective, 50 mg per day is enough for the males. This means that the athlete swallows one 25 mg tablet in the morning and the other one in the evening. In some cases one tablet is not enough. If Proviron is combined with Nolvadex (50 mg of Proviron per day and 20 mg of Nolvadex per day), almost complete suppression of estrogens takes place. Even better results are received from 50 mg of Proviron daily and 500-1000 mg of Fludestrin per day. Since Fludestrin is exclusively expensive preparation, (see Fludestrin), majority of the athletes don’t even think about such a combination.

Side effects for males at Proviron use of 2-3 tablets per day are exclusively small, so that Proviron may be relatively securely used in combination cycle for more than some weeks. Proviron is well tolerated by the liver and there will no be any liver dysfunctions for stated dosages. Proviron use for the athletes who are used to work under the slogan of „The more – the better”, could seem something of paradox. In the instruction of its preparation of Vistimon, Yenapharm writes the following: At high dosages it may lead to electrolyte and water retention in the organism and as a result to edemas”. Those, who use daily up to 2-4 tablets, may not worry on that. Perhaps the most often side effect of Proviron – we should most probably talk about following case – expressed sexual superstimulation and in particular cases – prolonged penis erection. Since the state is painful and may cause possible damages, there is sense in decreasing the preparation dosage or totally stop its usage. The female athletes should carefully enjoy Proviron since possible androgenic side effects are not excluded. Female athletes are recommended to use not more than one 25 mg tablet per day. Higher dosages and longer application duration than 4 weeks increase the risk of virilization cases. The female athletes that don’t have problems with Proviron, achieve good results by using 25 mg of Proviron daily and 20 mg of Nolvadex per day. They tell that in combination with the diet accelerated fat burn and quick musculature hardening takes place.
