Bayer Proviron 10 tabs (25 mg/tab)

Mesterolone - Proviron

Proviron operates as an anti-estrogen medication, effectively blocking estrogen receptors in the brain. This action prompts a notable increase in Gonadotropin release (LH and FSH), stimulating the testes to boost testosterone production. However, it does not exhibit any direct anabolic or androgenic properties.

Synthesized in the 1970s, Proviron faded from the market by the late 1990s. The manufacturing company, Schering, has ceased production, leading to rampant misinformation online. Many vendors offering Proviron may not be legitimate, and the available stock could be counterfeit, with reports of smuggling from regions like Asia, Russia, and Mexico raising concerns over authenticity.

Initially, Proviron was tested for treating depression and anxiety in both men and women. Findings revealed its potential to elevate Gonadotropin levels and enhance testosterone, rendering it useful in fertility treatments. Today, however, it is effectively discontinued and should not be considered for any medical use, as online offerings likely represent fake Proviron.

Indications

In its heyday, Proviron was indicated for addressing testosterone deficiencies and male infertility linked to hypothalamic, pituitary, or testicular dysfunctions.

Pharmacologie

More androgenic than anabolic, Proviron has gained popularity among athletes and bodybuilders for countering testosterone suppression following prolonged anabolic steroid use. Despite anticipation, most bodybuilders report disappointment, as it seldom yields muscle mass or strength improvements, often blaming the prevalence of counterfeit products contributing to these unfavorable outcomes.

Similar to Nolvadex or Arimidex, Proviron exhibits anti-estrogenic effects, preventing breast enlargement and water retention—common side effects from anabolic steroids. There are claims from some users about enhanced muscle definition; however, given the concurrent use of various anabolic steroids, attributing this effect solely to Proviron remains speculative. Knowledgeable athletes have largely shifted to alternatives like Arimidex and Nolvadex.

Femmes

Historically, Proviron was also utilized by women, though feedback on its efficacy in bodybuilding varies considerably. Due to its anti-estrogen properties, medical supervision is crucial for all females considering this drug.

Dosage

The recommended dosage for Mesterolone is 25 mg taken orally 2-3 times daily over several months, followed by a maintenance phase. It is rapidly absorbed, with a prolonged half-life of 12-24 hours, and can be detected in urine for two weeks post-administration. As it is not a potent anti-estrogen, it is often combined with Tamoxifen or Arimidex during the washout phase.

Effets secondaires

As with any medication, Proviron may cause rare but concerning side effects, which vary by individual, including:

• érections douloureuses
• perte de libido
• fatigue générale
• approfondissement de la voix
• augmentation de la croissance des cheveux
• acné et peau grasse

Contre-indications

Use of Proviron is not advisable in the following cases:

• enfants
• les femmes enceintes
• individuals with compromised liver function
• les personnes ayant reçu un diagnostic de cancer de la prostate
• les personnes souffrant d'allergies connues

Coût

The cost of Proviron is typically high when available, yet quality and purity remain uncertain. Most procurement channels are black-market, with 20 mg pills priced between $3-$4, and authenticity verification is nearly impossible.

Détection

Regarded as a banned substance by numerous sporting organizations, Proviron is subject to urine screening, with detection possible for up to two weeks due to its prolonged half-life.

Juridique

Possession of Proviron is not illegal; however, it is listed for mandatory screening in sports. In the USA, it falls under Schedule 3 of the Controlled Substances Act.

Le mot de la fin

Currently, Proviron resides purely in historical context, with genuine products no longer on the market. What is accessible today is likely counterfeit or contaminated. For body development purposes, Arimidex presents a more reliable alternative.
