Proviron

Proviron, or mesterolone, is a popular antiestrogen used by bodybuilders. It acts as an antiaromatase, which means it prevents the aromatization of steroids into estrogen. Proviron is frequently used by athletes on heavy cycles of steroids to prevent gynecomastia. It is also favored by competitive bodybuilders since a lower estrogen level corresponds with increased muscle hardness and lower water retention.One or two 25 mg per day should be sufficient to prevent gynecomastia. Proviron can also be combined with Nolvadex (tamoxifen citrate) to prevent any estrogen conversions from taking place. Side effects are extremely rare with dosages under 100 mg per day. One major problem with Proviron is that it tends to reduce the gains made from a cycle. This is due to the fact that Proviron is an androgen and therefore binds to androgen receptor sites within the body. With Proviron binding to androgen receptor sites, the other steroids present in the body (androgens) are blocked out and unable to take effect. Consequently, many athletes prefer to keep the intake of Proviron at its minimum effective dosage in order to make sufficient gains while still preventing gynecomastia. Proviron is usually fairly easy to obtain on the black market. Most versions are manufactured by Schering and cost about $1.50-$2 per 25 mg tab. Proviron can come in push-through strips or small glass vials. There is currently no need to worry about authenticity when buying Proviron since no counterfeits of this product are known exist.

Proviron: (mesterolone) 25 mg/tab 50 tab/bottle

This is an oral androgenic steroid which is commonly used as an estrogen antagonist. Once the drug is in the blood, it competes with estrogen receptor sites, in some cases this results in an end to aromatising effects of other steroids. Proviron itself will not aromatise and it is moderately toxic to the liver. Some women take the drug to enhance their androgen levels, giving them much harder looking muscles. Usually they stack Proviron with the other drugs they might be using. Male bodybuilders also use it in a pre-contest stack to attain a harder look. Average dosages are two to four tablets a day for men, half that for women. It is rarely seen on the market, and costs about $40 for 50 tabs.

Description: Proviron comes in a box with 10 - 25mg tablets in a blister pack. Proviron is a synthetic androgenic steroid and oral antiestrogen used by bodybuilders. A lot of bodybuilders take this substance for two main reasons. They use it to restore sexual disfunctions caused by steroid cycling. It will help get rid of the lack of sexual desire that most bodybuilders experience during a long steroid cycle. It also will help with the decreased sperm count and quality that steroids exhibit on the body. It does not however increase testosterone production in the body. It is also used as an anti-estrogen as well. Proviron provides a dual blocking scheme in that it prevents the aromitization of steroids as well as competes with estrogen to block the receptors as well. The bad thing about Proviron is that it does not help in maintaining strength and muscle gains after a steroid cycle whereas HCG, Clomid, and Teslac do. This reason alone keeps some people from using this drug. It does however block gyno and the increased water retention that steroids give the user. It does allow increased muscle hardness since the estrogen levels will be low which is of great benefit for a precontest bodybuilder. As far as side effects are concerned, Provirons main one is that it gives males a continuous hard-on (bummer for their girlfriends) at higher doses.

Effective Dose: 50 -100 mgs. per day by taking one to two 25 mg tablets in the morning and one to two 25 mg tablets in the evening.

Street Price: It normally sells for between $2+ per tablet on the street.

Stacking Info: This drug is commonly taken with Teslac, HCG, or Clomid. It is a popular precontest drug to increase muscle hardness. When taken along with Nolvadex, it almost completely blocks the effects of estrogen.Masterolone is a anadrogenic steroid with almost no anabolic action. It is used as a anti estrogen and gives the body a hard dense look.

Proviron:

Proviron is a regestrated trade mark of Scherling A/G Germany & Schering Mexico. Proviron/mesterolone Oral 25 mg Tablets are a multi-purpose Androgenic steroid with anabolic properties designed to be given to men in the early and medopausal stages of life. This steroid is most unique in the world because it is a non-17 Alpha Oral Androgen replacement for males. Provides health, added sex drive, the feeling of well being, vigor and sone qualties of youth. It may be taken over long periods of time. It does not aromatize,in fact bodybuilders take this in place of Nolvadex because Proviron is an Estrogen Antaganist. It is completly Syngerstic with all other steroids. Though as the best steroids goes not arroved by FDA but Schering world wide sales don´t seem to suffer. Proviron is sold in 37 Countries world wide. Sense it unique formula does not shut down the male own hormone production as with the highly androgenic T-Cyponiate and spermogenis is added to not subtracted from. Proviron could medically help 20 to 30 million males who experience male-medopause.


Proviron is a synthetic, orally effective androgen which does not have any anabolic characteristics. Proviron is used in medicine to to cure disturbances caused by a deficiency of male sex hormones and increase sperm count in males. Many athletes often use Proviron at the end of a steroid treatment in order to increase the reduced testosterone production. This, however, is not a good idea since Proviron 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. 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. Proviron 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 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, and Teslac). For this reason Proviron is unfortunately considered by many to be a useless and unnecessary compound.

You should be aware that Proviron is also an estrogen antagonist which prevents the aromatization of steroids. Unlike the antiestrogen Nolvadex which only blocks the estrogen receptors (see Nolvadex) Proviron already prevents the aromatizing of steroids. Therefore gynecomastia and increased water retention are successfully blocked. Since Proviron strongly suppresses the forming of estrogens no rebound effect occurs after discontinuation of use of the compound as is the case with Nolvadex where an aromatization of the steroids is not prevented. Proviron cures the problem of aromatization at its root while Nolvadex simply cures the symptoms of the already existing problem. For this reason male athletes should prefer Proviron to Nolvadex. With Proviron the athlete obtains more muscle hardness since the androgen level is increased and the estrogen concentration remains low. 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 increased muscle hardness. In the past it was common for althletes 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 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 25 mg tablet in the morning and another 25 mg 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. Even better results are achieved with 50 mg Proviron/ day and 500 - 1000 mg Teslac/day. Since Teslac is very expensive (see Teslac) most athletes do not consider this combination.

The side effects of Proviron in men are low at a dosage of 24 tablets/day so that Proviron, taken for example in combination with a steroid cycle, can be used comparatively without risk over several weeks. Since Proviron is well tolerated by the liver, liver dysfunctions do not occur in the given dosages. For athletes who are used to acting under the motto "more is better" the intake of Proviron could have a paradoxical effect. The most common side effect of Proviron is a distinct sexual overstimulation and in some cases continuous penis erection. Since this condition can be painful and lead to possible damages, a lower dosage or discontinu-ing the compound are the only sensible solutions. Female athletes should use Proviron with caution since possible androgenic side ef-fects 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 and in combination with a diet report an accelerated fat breakdown and continuously harder muscles.

Proviron is one of the very few steroid hormones which is still sufficiently available. The usual price is about $1.50-$2 per tablet. .
