Genesis Mesviron 25 100 tabs (25 mg/tab)

Mesterolone – Proviron

Proviron is a drug known for its anti-estrogenic effects. It blocks estrogen receptors, leading to increased secretion of Gonadotropins (LH and FSH), subsequently stimulating the testes to produce more testosterone. However, it does not exhibit direct anabolic or androgenic properties. Synthesized in the 70s, Proviron vanished from the market by the late 90s, with Schering ceasing production. Current online sellers often lack authenticity, and reports suggest that online stock might be smuggled from Asia, Russia, or Mexico, leading to doubts regarding its genuineness. Initially tested for treating depression and anxiety in both genders, studies revealed increases in Gonadotropins and testosterone, which later influenced its use in addressing fertility issues. Today, Proviron is considered unavailable for medical use, and products found online likely lack authenticity.

Indications

Historically, Proviron was indicated for testosterone deficiency and male infertility linked to issues in the hypothalamus, pituitary, or testes.

Pharmacology

Proviron shows more androgenic than anabolic activity, often utilized by athletes and bodybuilders to mitigate testosterone suppression from prolonged anabolic steroid use. Many bodybuilders report disappointment, claiming it fails to enhance muscle mass or strength, attributing this to the prevalence of counterfeit products. Due to its anti-estrogen properties, Proviron may prevent breast enlargement and water retention, often experienced as side effects of other anabolic steroids. Some users, however, claim it enhances muscle definition, though attributing changes solely to Proviron can be challenging amid other steroid use. Experienced athletes increasingly favor alternatives like Arimidex or Nolvadex over Proviron. FemalesHistorically, Proviron has been used by women as well. Despite claims of bodybuilding benefits, many females report little effect. Due to its anti-estrogen activity, female users should consult a health professional for monitoring.

Dosage

Typical dosage for Mesterolone is 25 mg orally, 2-3 times daily for several months, followed by a maintenance phase. When taken orally, Proviron is quickly absorbed and boasts a half-life of 12-24 hours, remaining detectable in urine for up to two weeks post-administration. It is often combined with Tamoxifen or Arimidex, particularly during washout phases.

Side effects

Proviron can be associated with rare side effects, which, although not universal, can be distressing, including:

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

Contraindications

Proviron is not recommended for:

• children
• pregnant individuals
• those with abnormal liver function
• patients with prostate cancer
• individuals with known allergies

Cost

When available, Proviron can be pricey, with quality and purity often questionable. Most products today circulate on the black market, smuggled into the US from Mexico and the Far East, with a cost of $3-$4 per 20 mg pill, raising concerns over authenticity.

Detection

Considered a banned substance by various sports organizations, Proviron is actively screened in urine tests and can be detected for up to two weeks following the last dose due to its prolonged half-life.

Legal

While possessing Proviron is not illegal, it is monitored by sports agencies. In the USA, it falls under the Controlled Substances Act as a Schedule 3 drug.

Final Word

Proviron has largely faded from relevance, with original products no longer obtainable. Current offerings are likely counterfeit or laced with unknown substances. For those aiming to enhance physical performance, exploring alternatives like Arimidex is recommended.
