Introduction to Proviron

Proviron is Sciroxx's brand name for Mesterolone, available in a potent 50 mg tablet form, doubling the standard dosage. Mesterolone balances a deficiency of androgen formation in various medical conditions of hypogonadism (insufficient testosterone production in males). This phenomenon is common with aging but also appears under certain types of endocrine conditions, such as the withdrawal of anabolic steroid usage.

Mechanism of Action

Mesterolone is an orally active derivative of dehydrotestosterone. It has a particularly high affinity for binding sites on sex hormone-binding globulin (SHBG) and is clinically proven to be about 4.4 times more active than dehydrotestosterone in this regard. SHBG is a protein present in the circulation that binds to testosterone (and other steroids), deactivating them. Approximately 2% of circulating steroids are found in their free form, while 98% are inactivated by binding to SHBG. The fact that Mesterolone has a higher affinity for SHBG than other steroids means it will compete and win the interaction with SHBG, allowing a higher percentage of other steroids to circulate in their free, active form in the plasma and have a more significant impact on target tissues.

Traits and Benefits

Proviron itself has a very weak (if any) anabolic effect due to its deactivation in muscle tissue, similar to dehydrotestosterone by certain enzymes. However, Proviron has a highly potent androgenic impact on target tissues such as the testicles and brain, which positively affects libido, erectile dysfunction, vitality, and spermatogenesis.

Proviron in Combination with Other Steroids

Proviron offers unique advantages when combined with other steroids, especially those like testosterone, which may be converted to estrogen. Testosterone, like other anabolic steroids, is converted to estrogen. While estrogen has some favorable effects in anabolic terms, it causes multiple unwanted side effects such as reduced libido, fluid retention, gynecomastia (an enlargement or swelling of breast tissue in males), and female-pattern fat accumulation. Proviron has been clinically shown to have direct anti-estrogen activity, as demonstrated in breast cancer treatment. This direct anti-estrogenic activity differs from the effect of aromatase inhibitors (AIs) such as Arimidex, which prevent the creation of estrogen, or selective estrogen receptor modulators (SERMs) such as Nolvadex, which occupy estrogen receptor sites.

Side Effects

Unlike other orally active steroids, Proviron possesses very low toxicity to the liver and may be used safely for long periods. At high dosages, it can suppress endogenous testosterone secretion. It may cause some androgenic side effects at androgenic target tissues, such as acne, increased sensitivity to male pattern baldness, and enlarged prostate at very high continuous dosages. Overall, however, Proviron is a very well-tolerated drug.

Proviron in Bodybuilding Cycles

Proviron may be used by itself as a mild anti-estrogen, potentially reducing the need for anti-estrogens such as Nolvadex or Arimidex, which may hinder the muscle-building effects of anabolic steroids. Proviron can also be combined with other anti-estrogens for a more comprehensive and effective overall synergistic anti-estrogen effect. This synergistic effect may, of course, reduce the required dosage of other anti-estrogen agents, which have some undesired effects during anabolic steroid applications.

Proviron may and should be run throughout the entire steroid cycle for optimal benefits. Its low toxicity, along with its aforementioned benefits, makes it well-suited to practically any bodybuilding cycle.

Proviron for TRT

By itself, Proviron effectively addresses androgen deficiency in terms of libido, vitality, energy, and androgenic functioning. It is well-suited for elderly patients due to its excellent benefits-to-side-effects ratio. However, Proviron provides negligible anabolic benefits; hence, in proper TRT, it is combined with testosterone. Typically, a dosage of 150-200 mg weekly  of testosterone may be effectively combined with 12.5-25 mg of Proviron per day for optimal synergistic effects.

Proviron and PCT

Proviron may be used only for the very initial part of PCT or for bridging between cycles. As an androgen, using Proviron will depress the testicular axis to some degree, though much less than other steroids. Therefore, it will not enable full recuperation of the testicular axis.

Administration and Dosage

Typical effective dosage for men is 25-50 mg per day. This dosage may go as high as 100 mg per day for bodybuilders before competitions due to its highly androgenic impact, which has a very appreciable effect on muscle appearance in terms of density and vascularity.
