Somatrop-Lab Mesterolone 50 tabs (25 mg/tab)

Mesterolone – Proviron

Proviron is an anti-estrogenic pharmaceutical that blocks estrogen receptors in the brain, enhancing the release of Gonadotropins (LH and FSH), thus stimulating increased testosterone production from the testes. Despite its effects, Proviron lacks direct anabolic or androgenic properties. Originally synthesized in the 1970s, it vanished from the market by the late 1990s; Schering, the manufacturer, has ceased production. Online claims of available Proviron are likely deceptive, with most sellers offering counterfeit products. Authentic sources are scarce, often linked to illegal smuggling primarily from Asia, Russia, and Mexico, casting doubt on the legitimacy of what is found online. It was initially explored as a treatment for depression and anxiety in both genders, revealing its ability to enhance Gonadotropins and testosterone levels, later leading to applications in addressing fertility issues. Currently, Proviron is unavailable for medical treatment, and any online options are highly questionable, likely fake or counterfeit.

Indications

Historically, Proviron was used for testosterone deficiency and male infertility arising from hypothalamic, pituitary, or testicular dysfunction.

Pharmacology

Proviron does exhibit more androgenic than anabolic activity, often sought by athletes and bodybuilders to counteract testosterone suppression following prolonged use of exogenous anabolic steroids. Many bodybuilders report disappointing results, citing minimal impacts on muscle mass and strength, suggesting that most experiences of effectiveness likely stem from counterfeit medications. Reliable testing is essential to determine a product’s authenticity. Proviron shares anti-estrogenic benefits similar to Nolvadex and Arimidex, helping to prevent common side effects like breast enlargement and water retention associated with anabolic steroid use. Some users claim it enhances muscle definition, but with multiple steroids involved, attributing specific results to Proviron is challenging. Most experienced athletes now prefer Arimidex or Nolvadex over Proviron. FemalesProviron has also seen use among women, but while some report bodybuilding benefits, many report minimal effects. Given its anti-estrogenic properties, female users must be monitored by healthcare professionals.

Dosage

The typical dosage for Mesterolone is 25 mg taken orally 2-3 times daily over several months, followed by a maintenance period. Upon oral administration, Proviron is quickly absorbed into the bloodstream and features a prolonged half-life (12-24 hours), remaining detectable in urine for at least two weeks post-use. Due to its deficiencies as an anti-estrogen, it’s frequently combined with Tamoxifen or Arimidex, especially during washout phases.

Side effects

Proviron may lead to some rare, but unsettling side effects, which include:

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

Contraindications

Use of Proviron is not advised for:

• children
• pregnant women
• individuals with liver abnormalities
• those diagnosed with prostate cancer
• people with allergies

Cost

When available, Proviron commands a high price. However, concerns regarding quality and purity persist, as all available products are sourced from the black market, predominantly smuggled into the U.S. from Mexico and Asia. A 20 mg pill typically costs $3-$4, with no guarantees on authenticity.

Detection

Proviron is banned by most sporting organizations and is routinely screened for in urinalysis. Due to its extended half-life, it can be detected in urine for up to two weeks post-administration.

Legal

Possessing Proviron isn’t illegal, but it is subject to scrutiny by sporting agencies. In the U.S., it falls under the Controlled Substances Act as a Schedule 3 drug.

Final Word

Proviron has effectively entered the annals of history as a defunct drug, with genuine products no longer available. What circulates in the market today is overwhelmingly likely to be counterfeit. For those focused on body development, alternatives like Arimidex provide a preferable option.
