Proviron is a purely androgenic steroid with no anabolic qualities. The drug was used both as an anti-estrogen that "prevents" estrogen from being produced through the aromatization of sex steroids, and for its hardening effect upon musculature. Unlike Nolvadex (which only keeps estrogen from bonding with its receptors by blocking them), Proviron actually prevents the formation of estrogen. Due to lower estrogen levels, athletes retained less water and prevented (for the most part) the formation of gyno and female pattern fat deposits.

*If it worked perfectly, we would not see all the obvious gyno at bodybuilding shows.

Proviron was popular as a post-cycle anti-estrogen. (To keep estrogen from becoming the dominant hormone and to kick up sex drive lost due to low androgen levels) In fact, it is used in medicine as a drug to increase sperm production and eliminate sexual dysfunction in males. In some cases Proviron is prescribed to decrease flow or stop menstruation in females. For males this only replaces the androgens levels, not cures the problems of low testosterone production. Though the reader should note that the decrease in circulatory estrogen in itself promotes increased HPTA activity. At one time Proviron was commonly used year round by many appearance oriented athletes to maintain hardness. Now, according to recent polls, more athletes are using ephedrine and Clenbuterol to replaced Proviron for this purpose. By the way, frequent and sometimes painful erections are side effects of Proviron use. (So?) Actually, an erection that lasts days can cause permanent damage and erectile problems.

*I commonly extorted another physiological response provided from the use of this drug. Proviron possesses the ability to bind SHBG at a high rate. By doing so other co-administered AAS (or endogenous testosterone) remained in an unbound/free state. This resulted in greater anabolic and androgenic activity realization with lower dosage requirements.

As to dosages, males "usually" administered 25-200mg daily and often combined it with Nolvadex (*See Nolvadex). Women athletes commonly reported virilizing side effects when employing Proviron. It should be noted that most women who reported this side effect also co-administered other androgens. At a dosage of 25-50-mg daily combined with Nolvadex most reported good results and few side effects. Teslac was believed to be a superior anti-aromatase drug (which shuts down estrogen production) but few considered it cost effective. 50mg Proviron and 250-1000mg Teslac, or 150mg Proviron and 20mg Nolvadex daily, was said to almost totally suppress estrogens. (Both during steroid cycles and after these dosages were quite effective)

(Mesterolone) is an androgenic/anabolic steroid with a particularly high affinity for SHBG (sex hormone binding globulin). SHBG is a protein that acts by binding to sex hormones and preventing them from interacting within the body at places like the AR (androgen receptor). Because of its high affinity with SHBG, Proviraplex' main use is to competitively bind with SHBG, freeing up more of the endogenous hormone to be active within the body. In effect, proviron acts as a 'magnifier' of the anabolic effects of steroid hormones. It also exhibits anti-aromatase activity, hence helping to prevent the conversion of certain steroids into estrogen. As a result, the intake of proviraplex whilst on a cycle of steroids, results in a 'hardening' of skeletal muscle - a look which is very popular amongst steroid users.

One side effect of provirion is the increased frequency and severity of erections, particularly during sleep/upon waking. Although provirion is an orally administered steroid, and is alkylated to survive the first pass through the liver, it is considered to be almost completely non-toxic to the liver. A typical dose of proviron might be from 25-100mg daily.

Proviron 25 is typically used for :

  • Post Cycle Therapy (PCT). It’s been shown to have zero negative effect on FSH (Follicle Stimulating Hormone) and LH (Leutenizing Hormone). Some studies indicate that it may even raise LH. These two hormones are responsible for giving the testicle the message to produce testosterone.
  • PCT for reducing the amount of oestrogen being converted from testosterone by binding to the aromatase enzyme thereby making it inactive.
  • Increasing the amount of free circulating testosterone in the body by binding to Sex Hormone Binding Globulin (SHBG).
  • Treating gynocomastia.
  • Increasing the effect of injected testosterone steroids by increasing the available quantity of the injected testosterone.
  • Fat burning due to Proviron 25 having a very strong bond with the AR (Androgen Receptor). It’s well documented that the stronger the bond, the stronger the lipolytic (fat burning) effect on adipose (fat) tissue. This effect is increased with testosterone cycles as testosterone increases the number of AR’s as well and therefore fat burning.

Recommended dose

Always take Proviron 25 exactly as prescribed by your doctor. If you are unsure, ask your pharmacist. Unless otherwise prescribed by a doctor, the normal dose is: A dose of 25mg twice daily should control excessive aromatization.

Dose during PCT

When to start your PCT Take the steroid with the longest half life of your stack. Half life x 3 is when you should start your PCT for a period of 4 – 6 weeks. 4 weeks (short-acting esters) – 6 weeks (long-acting esters).
PCT dose: Take two 50mg doses twice a day 12 hours apart. Reduce this dose to 25mg, twice per day for the last two weeks of your PCT.


Minimum recommended duration is 4 weeks and maximum duration is 6 weeks.
