Hilma Biocare Mesterolone 50 tabs (25 mg/tab)

Mesterolone – Proviron

Proviron is a unique medication known for its anti-estrogenic activity. By inhibiting estrogen receptors in the brain, it triggers the release of gonadotropins (LH and FSH), stimulating testosterone production in the testes. Notably, Proviron lacks direct anabolic or androgenic properties.

Originally synthesized in the 1970s, Proviron saw its market presence dwindle by the late 1990s, and it is currently discontinued by Schering, the pharmaceutical company. Most online sellers claiming to offer legitimate Proviron are likely selling counterfeit products. Genuine versions of this drug are estimated to be smuggled from regions such as Asia, Russia, and Mexico, casting doubt on its authenticity.

Initially explored for treating depression and anxiety in both men and women, studies revealed increases in gonadotropins and testosterone, leading to its consideration in fertility problems. However, Proviron is no longer used for any medical conditions, and much of what’s available online is either fake or ineffective.

Indications

Historically, Proviron was prescribed for testosterone deficiency and male infertility linked to issues within the hypothalamus, pituitary gland, or testes.

Pharmacology

Characterized by its androgenic rather than anabolic effects, Proviron is often used by athletes and bodybuilders to combat the testosterone suppression occurring after prolonged use of anabolic steroids. Many bodybuilders have reported disappointment, finding little enhancement in muscle mass or strength, often attributing this to the potential prevalence of fake Proviron.

With its anti-estrogen properties, akin to Nolvadex and Arimidex, Proviron helps prevent breast enlargement and water retention, common side effects of anabolic steroids. Some users claim it creates a more defined muscle appearance; however, the exact cause of muscle growth is frequently unclear due to simultaneous steroid use. During the washout phase, knowledgeable athletes are shifting towards Arimidex or Nolvadex, leaving Proviron behind.

Females

Proviron has previously been utilized by women, though its bodybuilding efficacy remains debated. Due to its anti-estrogen properties, female users are advised to consult healthcare professionals for monitoring.

Dosage

The typical dosage for Mesterolone is 25 mg taken orally 2-3 times daily for several months, followed by a maintenance phase. When ingested, Proviron is rapidly absorbed, boasting a long half-life of 12-24 hours, detectable in urine for up to two weeks after the last dose. As it is not a potent anti-estrogen, it is often combined with Tamoxifen or Arimidex during the washout stage.

Side Effects

As with any medication, Proviron is associated with rare but concerning side effects, including:

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

Contraindications

Proviron is unsuitable for:

• children
• pregnant women
• individuals with impaired liver function
• those with prostate cancer
• individuals with known allergies

Cost

When available, Proviron tends to be costly, raising concerns over its quality and purity. Currently, it circulates primarily on the black market, often smuggled into the US from Mexico and the Far East, with 20 mg pills priced between $3-$4, making authenticity challenging to verify.

Detection

Proviron is classified as a banned substance by most sports organizations, routinely screened for in urine tests. Due to its extended half-life, it remains detectable for up to two weeks following the last dosage.

Legal

While possession of Proviron is not illegal, it is monitored by sports organizations. In the USA, it falls under the controlled substances act as a Schedule 3 drug.

Final Word

Proviron is becoming a relic of the past, with the genuine product now virtually unavailable. Most offerings on the market today are likely counterfeit or contaminated. Athletes interested in optimizing performance should consider alternatives like Arimidex for better outcomes.
