Hubei Proviron 30 tabs (25 mg/tab) EXPIRATION

美斯特龙 – Proviron

Proviron is a medication recognized for its anti-estrogenic activity. It works by inhibiting estrogen receptors in the brain, leading to a boost in the release of Gonadotropins (LH and FSH), stimulating the testes to increase 睾酮 production. Despite its historical use, Proviron lacks any direct anabolic or androgenic activity. Originally synthesized in the 1970s, it faded from the marketplace by the late 1990s, with manufacturer Schering ceasing production. Most online sellers claiming to offer Proviron are likely either dishonest or selling counterfeit products, as genuine substances are no longer mass produced. Available versions online are often smuggled from regions such as Asia, Russia, and Mexico, raising authenticity concerns. Historically, Proviron was assessed for treating depression and anxiety in both genders, showing potential in increasing Gonadotropins and testosterone, later leading to its use for addressing fertility complications. Today, it is unavailable for medical use, and online products are widely considered fake.

适应症

Once, Proviron was prescribed for testosterone deficiency and male infertility linked to hypothalamic, pituitary, or testicular issues.

药理学

Proviron exhibits more androgenic activity than anabolic effects, often used by athletes and bodybuilders to counteract testosterone suppression post-external anabolic steroid usage. However, many bodybuilders have reported disappointment, claiming it fails to enhance muscle mass or strength, attributing their experiences possibly to counterfeit products. As a confirmed anti-estrogen agent similar to Nolvadex or Arimidex, it can help prevent breast enlargement and fluid retention typical of anabolic steroids. Some users report enhanced muscle definition, although the effects may stem from concurrent anabolic steroid use, muddling causality. Proviron has mainly been utilized during washout periods to sustain testosterone enhancement. Nowadays, many knowledgeable athletes prefer Arimidex or Nolvadex over Proviron. 女性 Proviron’s use among females has also been reported, with variable feedback regarding its bodybuilding advantages. Given its anti-estrogenic properties, women using this medication should do so under medical supervision.

用量

The recommended dosage of Mesterolone is 25 mg orally, taken 2-3 times daily for several months, followed by maintenance treatment. When ingested, Proviron is quickly absorbed, possessing a lengthy half-life of 12-24 hours and remaining detectable in urine for at least two weeks following the last dose. Due to its limited effectiveness as an anti-estrogen, it’s frequently combined with Tamoxifen or Arimidex, especially during washout periods.

副作用

Proviron may bring about some rare but concerning side effects, which can include:

• 勃起疼痛
• 性欲减退
• 一般疲劳
• 声音加深
• 过度生发
• acne and oily skin

禁忌症

Proviron use is not recommended for:

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

费用

When available, Proviron is costly, but the quality and purity remain questionable. Currently, it’s primarily sourced from the black market, often smuggled into the US from Mexico and the Far East, with single 20 mg pills retailing between $3-$4—creating uncertainty regarding authenticity.

检测

Proviron is categorized as a banned substance by many sports organizations and is regularly tested in urine samples. Thanks to its extended half-life, the drug can be detected for up to two weeks after the last dose.

法律

Although possessing Proviron is not illegal, it is subject to screening by sports authorities. In the USA, Proviron is classified under the Controlled Substances Act as a Schedule III drug.

最后的话

Proviron has become a relic of the past, with authentic products no longer available. Current offerings are likely counterfeit or mixed with other substances. For bodybuilding enthusiasts seeking effective results, Arimidex presents a superior alternative.
