Sterling Knight Proviron 25 60 tabs (25 mg/tab)

Mesterolone – Proviron

Proviron is a notable drug recognized for its anti-estrogen properties. By inhibiting estrogen receptors in the brain, it stimulates the release of Gonadotropins (LH and FSH), prompting the testes to boost testosterone production.

This drug is devoid of direct anabolic or androgenic effects. Initially synthesized in the 1970s, Proviron vanished from the market by the late 90s, with its manufacturer, Schering, ceasing production. Online vendors claiming to sell Proviron are often misleading, with a high likelihood of counterfeit products. Authenticity issues arise as smuggling from regions like Asia, Russia, and Mexico casts doubt on available sources.

Originally tested for treating depression and anxiety in both men and women, research revealed its capacity to elevate Gonadotropins and enhance testosterone levels, which later led to its application in addressing fertility issues. Today, the medical use of Proviron is obsolete, and any online listings are likely not genuine.

Indications

Proviron was once prescribed for testosterone deficiency and male infertility driven by hypothalamic, pituitary, or testicular abnormalities.

Pharmacology

Proviron exhibits predominantly androgenic rather than anabolic action. Athletes and bodybuilders may use it to counteract testosterone suppression from extended anabolic steroids usage. However, many bodybuilders express disappointment, noting insufficient gains in muscle mass and strength.

Reports of counterfeit Proviron are prevalent, emphasizing the importance of laboratory testing to determine product authenticity. Proviron’s anti-estrogen effects mirror those of Nolvadex or Arimidex, effectively mitigating breast enlargement and water retention commonly associated with anabolic steroids.

Some users claim it induces muscle bulging; however, concurrent use of other steroids complicates attributing results solely to Proviron. It remains primarily utilized during washout phases to sustain testosterone levels, though informed athletes often prefer alternatives like Arimidex or Nolvadex.

Females

Historically, females have utilized Proviron as well, but experiences vary significantly. Although some report favorable bodybuilding effects, others experience minimal benefits. Due to its anti-estrogen properties, female users should always consult healthcare professionals for monitoring.

Dosage

The recommended dose of Mesterolone is 25 mg orally, administered 2-3 times daily for several months, followed by maintenance dosing. Administered orally, Proviron is rapidly absorbed, featuring a lengthy half-life of approximately 12-24 hours and detectable in urine up to two weeks post-dose. Often combined with Tamoxifen or Arimidex, it is most effective during washout periods.

Side effects

Like all medications, Proviron may present rare side effects, which, while not ubiquitous, can be concerning. Possible side effects include:

• painful erections
• loss of libido
• general fatigue
• deepening of voice
• increased hair growth
• acne and oily skin

Contraindications

Proviron is contraindicated in:

• children
• pregnant women
• individuals with abnormal liver function
• anyone diagnosed with prostate cancer
• those with allergies

Cost

When available, Proviron is costly. The quality and purity remain uncertain, as it is predominantly found on the black market, often smuggled into the US from Mexico and the Far East. A 20 mg tablet typically costs between $3-$4, with no guarantee of authenticity.

Detection

Proviron is prohibited by many sports organizations and regularly screened in urine tests. Due to its prolonged half-life, it can be detected for up to two weeks following the last use.

Legal

While possession of Proviron is not strictly illegal, most sporting agencies include it in routine urine screenings. In the United States, it falls under the classification of a schedule 3 controlled substance.

Final Word

Proviron is now largely a relic of the past, with authentic products no longer accessible. Most offerings available today are likely counterfeit or contaminated. For body enhancement goals, alternatives like Arimidex present a more viable option.
