Bayer Proviron 20 tabs (25 mg/tab)

Mesterolone - Proviron

Proviron is a pharmaceutical compound renowned for its anti-estrogenic activity. By inhibiting estrogen receptors in the brain, it stimulates the release of gonadotropins (LH and FSH), prompting the testes to increase testosteroon production. Despite this mechanism, Proviron exhibits neither direct anabolic nor androgenic activity.

Synthesized in the 1970s, it faded from the market by the late 1990s. The manufacturer, Schering, has ceased its production, leading to widespread counterfeit distribution online. Many sellers purporting to offer authentic Proviron are likely dishonest or dealing in counterfeit products, primarily smuggled from Asia, Russia, and Mexico.

Initially explored as a treatment for depression and anxiety in both men and women, studies revealed its capacity to elevate gonadotropin levels and thus enhance testosterone levels. Consequently, it took on a role in addressing fertility issues, yet today, its clinical applications have ceased entirely, with available products often suspect.

Näidustused

Historically, Proviron was used to remediate testosterone deficiency and male infertility resulting from hypothalamic, pituitary, or testicular dysfunction.

Farmakoloogia

Proviron exhibits more androgenic activity than anabolic effects, appealing to athletes and bodybuilders looking to recover from testosterone suppression following prolonged anabolic steroid use. However, many bodybuilders have expressed disappointment, claiming it fails to boost muscle mass or strength, often deeming it an ineffective investment. Reports of counterfeit products further complicate its use, as without laboratory testing, determining authenticity is impossible.

This compound carries anti-estrogen properties akin to Nolvadex or Arimidex, effectively mitigating gynecomastia and water retention associated with anabolic steroids. Users occasionally report muscle definition enhancement, but attributing this to Proviron is challenging due to concurrent anabolic steroid usage.

It is commonly employed during the washout phase to sustain testosterone levels, yet seasoned athletes have shifted towards alternatives like Arimidex or Nolvadex.

Naised

Proviron has been utilized by women, predominantly in bodybuilding contexts. Nevertheless, while some claim effectiveness, an equal number report minimal impact. Due to its anti-estrogen activity, regular medical supervision is recommended for female users.

Annustamine

The recommended dosage for Mesterolone is 25 mg taken orally 2-3 times daily over several months, followed by maintenance therapy. Proviron is rapidly absorbed, boasting a significant half-life of 12-24 hours, detectable in urine for up to two weeks post-dose. Often, it is paired with Tamoxifen or Arimidex during the washout period.

Kõrvaltoimed

As with any medication, Proviron may present rare side effects, disturbing for some individuals. Possible effects include:

• valulikud erektsioonid
• libiido kadumine

Vastunäidustused

Kulud

The available stocks of Proviron tend to be costly, muddied by quality and purity doubts. Currently, all transactions occur through black-market channels, primarily smuggled from Mexico and Asia, costing about $3-$4 per 20 mg tablet, with authenticity difficult to ascertain.

Avastamine

Proviron is classified as a prohibited substance by many sports organizations and is routinely screened for in urine tests. Due to its extended half-life, it remains traceable for up to two weeks after ingestion.

Juriidiline

While possessing Proviron is not illegal, it is subject to monitoring by various sporting bodies. In the United States, it falls under the Controlled Substance Act as a Schedule 3 drug.

Lõppsõna

Proviron is largely relegated to the annals of pharmacy history, with genuine products no longer available. Current offerings are mostly counterfeit or contaminated. For individuals focused on body development, alternatives like Arimidex may prove more effective.
