Bayer Proviron 10 tabs (25 mg/tab) EXPIRATION

Mesterolone – Proviron

Proviron serves as a drug with notable anti-estrogenic activity. It effectively blocks estrogen receptors in the brain, leading to an increase in Gonadotropin release (LH and FSH), which stimulates the testes to produce heightened testosterone levels. Notably, Proviron lacks direct anabolic or androgenic activity. Initially synthesized in the 1970s, it vanished from the market by the late 1990s and is no longer manufactured by Schering. Products advertised online as Proviron are often misleading, with many likely being counterfeit or unauthorized. Reports suggest counterfeit Proviron is smuggled from regions such as Asia, Russia, and Mexico, undermining the drug’s authenticity. Originally, Proviron was explored for treating depression and anxiety in both men and women. Studies revealed its capacity to elevate Gonadotropins (LH & FSH) and testosterone levels. Although this led to its utilization for fertility issues, it is now obsolete in medical applications, and any available online supply is highly suspect.

Indications

In its prime, Proviron was prescribed for testosterone deficiency and male infertility related to hypothalamic, pituitary, or testicular dysfunction.

Pharmacology

Proviron exhibits more androgenic than anabolic properties, often misused by athletes and bodybuilders to counteract testosterone suppression resulting from prolonged anabolic steroid use. Sadly, numerous bodybuilders report dissatisfaction, claiming it does not enhance muscle mass or strength, viewing it as ineffective. Furthermore, the legitimate Proviron’s inaccessibility may contribute to the prevalence of counterfeit products, making laboratory testing essential for verification. Additionally, Proviron’s anti-estrogen activity mimics that of Nolvadex and Arimidex, mitigating common anabolic steroid side effects like breast enlargement and water retention. Some users report superficial muscle definition during washout phases; however, many also consume multiple anabolic compounds, complicating the identification of the exact contributor to muscle growth. Knowledgeable athletes tend to prefer alternatives like Arimidex or Nolvadex over Proviron. Females Proviron has been utilized by women, too. Though some tout its bodybuilding benefits, numerous females dismiss its efficacy. Due to its anti-estrogen properties, female users should undergo monitoring by healthcare professionals.

Dosage

The recommended dose of Mesterolone is 25 mg taken orally 2-3 times daily for several months, followed by maintenance therapy. When consumed, Proviron is swiftly absorbed and possesses a lengthy half-life of 12-24 hours, remaining detectable in urine for up to two weeks post-dose. Due to its limited effectiveness as an anti-estrogen, Proviron is often paired with drugs like Tamoxifen or Arimidex and utilized during washout periods.

Side Effects

Like any pharmaceutical, Proviron may produce rare yet unsettling side effects, including:

• painful erections
• reduced libido
• general fatigue
• deepening voice
• excess hair growth
• acne, oily skin

Contraindications

Proviron is contraindicated for:

• children
• pregnant individuals
• those with liver dysfunction
• people diagnosed with prostate cancer
• individuals with known allergies

Cost

When accessible, Proviron is costly, with concerns surrounding purity and quality. Predominantly sourced on the black market, much of it is smuggled from Mexico and Asia, costing between $3 and $4 per 20 mg pill, complicating authenticity verification.

Detection

Banned by various sports authorities, Proviron is rigorously screened in urine due to its extended half-life, remaining detectable up to two weeks after the final dosage.

Legal Status

While possession of Proviron isn’t illegal, it is subject to drug screenings in sports. In the United States, it is classified under the Controlled Substance Act as a Schedule III drug.

Final Word

Proviron is now a relic of the past, with genuine products no longer available. Current offerings are likely counterfeit or contaminated. For those interested in muscle development, drugs like Arimidex are recommended as superior alternatives.
