Bayer Proviron 10 tabs (25 mg/tab)

Mesterolone – Proviron

Proviron is an anti-estrogenic medication that works by blocking estrogen receptors in the brain, leading to an increase in Gonadotropins (LH and FSH), stimulating the testes to produce more testosterone. It lacks any direct anabolic or androgenic properties.

Synthesized in the 1970s, Proviron was withdrawn from the market by the late 1990s and is no longer manufactured by Schering. Many online sellers claiming to offer genuine products are likely deceptive or dealing in counterfeit goods, as legitimate production has ceased. Reports indicate that smuggled versions are commonly sourced from regions like Asia, Russia, and Mexico, casting doubt on their authenticity.

Originally proposed for treating depression and anxiety in both sexes, studies revealed its role in enhancing Gonadotropins and testosterone levels, transitioning its use to address fertility issues. However, Proviron is no longer prescribed for medical conditions, and any available products online are likely to be fraudulent or counterfeit.

Indications

Proviron was once indicated for managing testosterone deficiency and male infertility linked to hypothalamic, pituitary, or testicular issues.

Pharmacology

Proviron is known for more androgenic than anabolic influence and has been utilized by athletes and bodybuilders to aid recovery from testosterone suppression following prolonged use of anabolic steroids. Many bodybuilders express disappointment with its effectiveness, often claiming it doesn’t enhance muscle mass or strength, which might be attributed to counterfeit versions widely circulated.

This anti-estrogen characteristic helps mitigate breast enlargement and water retention associated with anabolic steroids. Some users report enhanced muscle definition, but those claims are often obscured by concurrent use of other steroids.

Females

In earlier years, females also used Proviron, yet the feedback regarding its bodybuilding effects has been mixed. Due to its anti-estrogen properties, female users should maintain consistent follow-up with a healthcare professional.

Dosage

The typical dosage for Mesterolone is 25 mg orally two to three times daily over several months, followed by a maintenance phase. It is rapidly absorbed and has a half-life of 12-24 hours, remaining detectable in urine for at least two weeks post-administration. Often, it’s combined with Tamoxifen or Arimidex during the washout phase.

Side effects

Proviron may be associated with rare, yet concerning side effects, including:

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

Contraindications

Proviron is not recommended for:

• children
• pregnant women
• individuals with liver dysfunction
• prostate cancer patients
• those with known allergies

Cost

When available, Proviron can be quite costly, with quality often questionable; it is primarily accessible through black-market channels. A 20 mg tablet may range from $3-$4, but verifying authenticity remains impossible.

Detection

Most sports organizations ban Proviron and routinely test for it in urine. Its prolonged half-life allows it to be detected for up to two weeks after the last dose.

Legal

While possessing Proviron is not illegal, it is prohibited in competitive sports. In the USA, it is classified as a Schedule III controlled substance.

Final Word

Proviron now belongs to the annals of history, with authentic products unavailable. Current alternatives are likely counterfeit, rendering Arimidex a preferred choice for those pursuing body development.
