Mesterolone – Proviron
Proviron is a medication recognized for its anti-estrogenic properties. By inhibiting estrogen receptors in the brain, it promotes a significant release of Gonadotropins (LH and FSH), stimulating testosterone production in the testes. It’s important to note that Proviron lacks direct anabolic or androgenic effects. Synthesized in the 1970s, it vanished from the market by the late 1990s, with its manufacturer, Schering, no longer producing it. Most online sellers claiming to offer Proviron are likely fraudulent, as the drug is no longer mass-produced. Reports indicate that it may be smuggled from Asia, Russia, and Mexico, raising concerns over authenticity. Once tested for treating depression and anxiety, it was later found to elevate testosterone levels, leading to its use for fertility issues. Currently, Proviron is unavailable and not endorsed for any medical condition, making online purchases problematic and often dangerous.
Indications
In the past, Proviron was used to address testosterone deficiency and male infertility related to hypothalamic, pituitary, or testicular dysfunctions.
Pharmacology
Proviron exhibits more androgenic than anabolic activity. Athletes and bodybuilders often employ it to counteract testosterone suppression from prolonged anabolic steroid use. However, many users report disappointment, asserting it does little to enhance muscle mass or strength, often considering it ineffective. This skepticism may stem from widespread counterfeiting, as authentic Proviron is unheard of without laboratory confirmation. Proviron does demonstrate anti-estrogen effects similar to Nolvadex or Arimidex, mitigating common side effects like breast enlargement and water retention associated with anabolic steroids. Some users claim modest muscle definition, but most athletes have shifted to more effective alternatives like Arimidex or Nolvadex.
Females
Historically, Proviron has been administered to females as well. While some report success in bodybuilding, numerous women assert minimal effects. Due to its anti-estrogen activity, female users should always consult with a healthcare provider.
Dosage
The common dosage for Mesterolone is 25 mg taken orally 2-3 times daily over several months, followed by maintenance therapy. Proviron is rapidly absorbed into the bloodstream, boasting a long half-life of 12-24 hours, remaining detectable in urine for up to 2 weeks post-administration. It is often paired with Tamoxifen or Arimidex during the washout phase due to its limited efficacy as an anti-estrogen.
Side Effects
Proviron can cause rare but concerning side effects, which may include:
- Painful erections
- Loss of libido
- General fatigue
- Deepening of voice
- Increased hair growth
- Acne and oily skin
Contraindications
Proviron use is inadvisable for:
- Children
- Pregnant women
- Individuals with liver abnormalities
- Prostate cancer patients
- Those with known allergies
Cost
When available, Proviron is costly, with its quality and purity highly questionable. Currently, it is only obtainable on the black market, primarily smuggled from Mexico and the Far East, with 20 mg pills selling for $3-$4, often with no way to verify authenticity.
Detection
Proviron is banned by most sports organizations and is routinely tested for in urine. Its extended half-life allows for detection for up to 2 weeks following the last dose.
Legal
Possession of Proviron is not illegal; however, all sports agencies actively test for it in athletes. In the United States, it is categorized as a Schedule 3 controlled substance.
Final Word
Proviron remains a relic of the past, with authentic products no longer available. Current offerings are likely counterfeit or adulterated. For individuals seeking to enhance their physique, alternatives like Arimidex would be a far superior selection.
