Providex Tablet| 50mg Mesterolone| Buy Proviron Domestic| USA

Introduction to Proviron

Providex is Sciroxx's brand name for Mesterolone, also known as Proviron. It’s available in a potent 50 mg tablet form, doubling the standard dosage. Mesterolone helps balance androgen deficiencies in various medical conditions, such as hypogonadism (insufficient testosterone production in males). This condition is common with aging but can also occur due to certain endocrine disorders, including the withdrawal of anabolic steroid usage.

Mechanism of Action, Traits, and Benefits

Mesterolone is an orally active derivative of dehydrotestosterone (DHT). While Proviron itself has a very weak (if any) anabolic effect due to its deactivation in muscle tissue by certain enzymes, it has a highly potent androgenic impact on target tissues such as the testicles, prostate, and brain.

Providex has a particularly high affinity for binding to 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. Since Mesterolone has a higher affinity for SHBG than other steroids, it competes effectively, 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.

Proviron in Combination with Other Steroids

Proviron offers unique advantages when combined with other steroids, especially those like testosterone, which may convert to estrogen. While estrogen has some favorable effects in anabolic terms, it also causes unwanted side effects such as reduced libido, fluid retention, gynecomastia (enlargement 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 anti-estrogenic effect differs from aromatase inhibitors (AIs) like Arimidex, which prevent the creation of estrogen, or selective estrogen receptor modulators (SERMs) like Nolvadex, which occupy estrogen receptor sites.

Side Effects

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

Proviron in Bodybuilding Cycles: Dosage and Benefits

Proviron is a valuable addition both on cycle in bodybuilding and as part of hormonal therapy. Proviron can be used by itself as a mild anti-estrogen, potentially reducing the need for anti-estrogens like 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 synergy may reduce the required dosage of other anti-estrogen agents, which have some undesired effects during anabolic steroid applications.

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

Proviron and Libido: Effects and Dosage

As mentioned, Proviron has a distinct androgenic impact, which positively affects libido, erectile quality, sexual performance, vitality, and spermatogenesis. These traits stem from its high affinity for androgen receptors in both the brain and the genitals. A basic dosage of 25mg daily provides the desired effects, with empirical data suggesting that taking Proviron 1.5-2 hours before sexual activity will ensure peak performance and libido, considering its pharmacokinetics (see half-life section below).

Proviron and PCT

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

Administration and Dosage in Bodybuilding

The 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 noticeable effect on muscle appearance in terms of density and vascularity.

Proviron Half-Life

Proviron is taken orally and reaches peak serum concentration within 1.6 ± 0.6 hours. After this, Proviron's serum concentration decreases gradually, with a half-life of about 12-13 hours, meaning half of the ingested dosage is eliminated within this time frame. While Proviron is suited for a single daily dosage, two daily doses are recommended for optimal effectiveness.

Proviron vs. Masteron

Proviron and Masteron have similar chemical structures, as both are DHT derivatives. The first distinction is that Proviron is an oral steroid, while Masteron is only effective via intramuscular injection. Both Proviron and Masteron have a high affinity for SHBG, but Proviron is distinctly more prominent in this regard, with a measured affinity about 4 times higher than DHT—the highest among steroids. On the other hand, Proviron shows negligible anabolic activity, while Masteron retains anabolic activity. Although Masteron is not known for muscle building, it still shows anabolic effects comparable to those of Primobolan.
