One of the most popular antiestrogens for sportsmen on anabolic steroids, Proviron is considered as the best oral androgenic steroid in today’s world. It is admired by sportsmen and health-conscious individuals across the world to stimulate the testes to make more of testosterone, the male sex hormone.

Proviron has the molecular formula of C20H32O2 and its molecular weight is 304.4716 g/mol at the base. The androgenic-anabolic ratio of Proviron is 30-40/100-150 and its active life is up to 12 hours; it can be detected within five to six weeks and has the chemical name of 1 alpha-methyl-17 beta-hydroxy-5 alpha-androstan-3-one.

The antiestrogen, also known as Mesterolone and Provironum, is medically prescribed to offer significant relief to hypogonadal males afflicted with testosterone deficiency and treat individuals with sexual dysfunction. The drug is a derivative of dihydrotestosterone (DHT) and has the unique ability to surge the release of luteinizing hormone and follicle-stimulating hormone. It is also recommended to middle- and old-aged men experiencing declining physical activity and mental alertness and is highly effective in treating health conditions, including weak memory, disturbances of libido and potency, irritability, disturbances of sleep, depressive moods, reduced efficiency, easy fatigability, lack of concentration, and general vegetative complaints.

Proviron is also useful in promoting the development of secondary male sex characteristics in incidents of prepuberal hypogonadism and may also be prescribed as part of the substitution therapy where a loss of gonadal function has occurred post-puberally. Proviron may be prescribed to treat individuals afflicted with low sexual desire or impotency.

In the world of professional sports, Proviron is admired by sportsmen as it is well tolerated by the liver and does not impair spermatogenesis (process of producing sperm). Proviron can actually increase the quality and quantity of sperm and thus increases the chances of procreation (reproduction). It is commonly used by sportsmen, just before the end or at the end of a steroid cycle, to restore the production of testosterone. Proviron is also used by sportsmen on harsh and aromatizable steroids such as testosterone derivatives to avoid estrogenic side effects, including oily skin, gynecomastia, and fluid retention. In short, Proviron has the ability to make other anabolic steroids and performance enhancing drugs more effective by inhibiting their conversion to estrogens besides improving the count of circulating free testosterone in the body and providing a more hardened and quality look to muscles.

The recommended dose of Proviron for men is 25-100 mg per day, with or without meals. This drug should not be abused or used without medical recommendation and guidance else it can lead to side effects, such as oily skin, acne, fatigue, reduced libido, and painful erections. It is not recommended to pregnant and breastfeeding women or those suffering with prostate cancer. If Proviron users are taking anticoagulants, antidiabetics, cyclosporine, and thyroxine, medical guidance is very important as it can interfere with absorption of these medicines. In order to maintain its shelf life, Proviron must be stored below 30°C and kept away from direct heat, moisture, and sunlight.
