Proviron is often regarded as one of the most underrated substances in a bodybuilder's toolbox. It isn't a conventional anti-estrogen; rather, Proviron (with Mesterolone as its active ingredient) is an anabolic steroid derived from dihydrotestosterone. Structurally, the Mesterolone molecule bears a strong resemblance to Methenolone, with their differences comparable to those between males and females.
It can be primarily categorized as an aromatase inhibitor, hence the “mostly” designation. This stems from its partial estrogen receptor-blocking capability, even though this function is not its primary action. Proviron's unique characteristics go beyond this, as it offers several beneficial properties. One notable feature is its ability to boost the levels of free testosterone in the bloodstream by binding to sex hormone-binding globulin, thereby reducing the latter's effects.
Enhancing the quantity of free testosterone in the body is particularly advantageous. Because of this attribute, many athletes utilize Proviron for a period of 5-7 days around the midpoint of their anabolic steroid cycles. However, some researchers label Mesterolone more as an anti-androgen, suggesting it may be ill-suited for use during anabolic steroid cycles, though this perspective may not fully capture its benefits.
In pre-competitive preparations, Proviron is utilized to enhance muscle firmness and definition, making it popular among actors and models who wish to highlight their musculature before performances. Additionally, Proviron possesses the interesting trait of significantly boosting libido in men (often resulting in spontaneous erections), which makes it especially useful alongside compounds that may diminish libido (such as Trenbolone, Nandrolone, Norethandrolone, and Ethylestrenol). Its efficacy in recovery is best realized when combined with Tamoxifen (Nolvadex) or Clomiphene (Clomid).
The recommended daily dosage of Proviron ranges from 20 to 100 mg, typically translating to 1-5 tablets.
