Euro-Pharmacies Proviron 50 tabs (25 mg/tab)

Mesterolone – Proviron

Proviron is an anti-estrogenic medication that blocks estrogen receptors in the brain, leading to an increase in Gonadotropins (LH and FSH) and stimulating the testes to produce more testosterone. Notably, this drug lacks direct anabolic or androgenic properties.

Synthesized in the 1970s, Proviron disappeared from the market by the late 1990s, and its manufacturer, Schering, no longer produces it. Many online sellers claiming to offer this product are likely misleading consumers, putting authenticity into question. Some reports indicate that products are smuggled in from regions like Asia, Russia, and Mexico, further complicating the verification of authenticity.

Initially tested for treating depression and anxiety in both sexes, studies revealed that this drug increased Gonadotropins (LH & FSH) and testosterone levels, leading to its application in addressing fertility issues. However, Proviron is currently not available for medical use, with much of what can be found online potentially being counterfeit or fake.

Indications

Historically, Proviron was prescribed for testosterone deficiency and male infertility stemming from issues within the hypothalamus, pituitary, or testes.

Pharmacology

With more androgenic activity than anabolic effects, Proviron is utilized by athletes and bodybuilders to recover from testosterone suppression post-usage of exogenous anabolic steroids. Many users express disappointment, citing a lack of muscle mass or strength enhancement, often attributing this to the prevalence of counterfeit products. Authenticity verification through chemistry lab testing remains essential for consumers.

The drug acts similarly to Nolvadex or Arimidex in terms of anti-estrogen effects, preventing breast enlargement and water retention linked to anabolic steroids. While some users claim it enhances muscle definition, the reality is often blurred by concurrent anabolic steroid usage, making it difficult to attribute growth to any single substance. Most seasoned athletes have shifted towards using Arimidex or Nolvadex instead.

Females

In prior instances, women have also used Proviron, though reports on its efficacy for bodybuilding are mixed. Due to its anti-estrogen properties, female users require monitoring by healthcare professionals.

Dosage

The recommended oral dosage for Mesterolone is 25 mg taken 2-3 times daily over several months, followed by a maintenance period. When ingested, Proviron is rapidly absorbed, boasting a long half-life of 12-24 hours, detectable in urine for at least 2 weeks after the last dose. Its limited effectiveness as an anti-estrogen often necessitates combination with Tamoxifen or Arimidex, particularly during washout phases.

Side Effects

Like any medication, Proviron may present rare side effects, which, although not universal, can be concerning. Reported side effects include:

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

Contraindications

Usage of Proviron is contraindicated in:

• children
• pregnant women
• individuals with liver dysfunction
• those with a history of prostate cancer
• anyone with known allergies

Cost

When available, Proviron is costly, with its quality often questionable. The remaining supply is primarily found on the black market, predominantly smuggled into the U.S. from places like Mexico and the Far East. A 20 mg pill can range from $3 to $4, leaving no assurance regarding its authenticity.

Detection

As a banned substance within many sports organizations, Proviron is routinely screened for via urine tests. Given its extended half-life, it can remain detectable for up to 2 weeks post-administration.

Legal

Possessing Proviron is not illegal; however, all competitive sporting bodies monitor for it in urine tests. In the USA, Proviron is categorized as a controlled substance under Schedule III of the Controlled Substances Act.

Final Word

Currently, Proviron belongs to the annals of history, with authentic products virtually non-existent. What is offered today is likely counterfeit or contaminated. For those pursuing bodybuilding goals, alternatives like Arimidex are recommended for better results.
