Proviron is a purely androgenic steroid with no anabolic qualities. The drug wasused both as an anti-estrogen that "prevents" estrogen from being produced through thearomatization of sex steroids, and for its hardening effect upon musculature. UnlikeNolvadex (which only keeps estrogen from bonding with its receptors by blockingthem), Proviron actually prevents the formation of estrogen. Due to lower estrogen levels,athletes retained less water and prevented (for the most part) the formation of gyno andfemale pattern fat deposits.
*If it worked perfectly, we would not see all the obvious gyno at bodybuilding shows.
Proviron was popular as a post-cycle anti-estrogen. (To keep estrogen frombecoming the dominant hormone and to kick up sex drive lost due to low androgenlevels) In fact, it is used in medicine as a drug to increase sperm production and eliminatesexual dysfunction in males. In some cases Proviron is prescribed to decrease flow orstop menstruation in females. For males this only replaces the androgens levels, not curesthe problems of low testosterone production. Though the reader should note that thedecrease in circulatory estrogen in itself promotes increased HPTA activity. At one timeProviron was commonly used year round by many appearance oriented athletes tomaintain hardness. Now, according to recent polls, more athletes are using ephedrine andClenbuterol to replaced Proviron for this purpose. By the way, frequent and sometimespainful erections are side effects of Proviron use. (So?) Actually, an erection that lastsdays can cause permanent damage and erectile problems.
*I commonly extorted another physiological response provided from the use of thisdrug. Proviron possesses the ability to bind SHBG at a high rate. By doing so other coadministeredAAS (or endogenous testosterone) remained in an unbound/free state. Thisresulted in greater anabolic and androgenic activity realization with lower dosagerequirements.
As to dosages, males "usually" administered 25-200mg daily and often combinedit with Nolvadex (*See Nolvadex). Women athletes commonly reported virilizing sideeffects when employing Proviron. It should be noted that most women who reported thisside effect also co-administered other androgens. At a dosage of 25-50-mg dailycombined with Nolvadex most reported good results and few side effects. Teslac wasbelieved to be a superior anti-aromatase drug (which shuts down estrogen production) butfew considered it cost effective. 50mg Proviron and 250-1000mg Teslac, or 150mgProviron and 20mg Nolvadex daily, was said to almost totally suppress estrogens. (Bothduring steroid cycles and after these dosages were quite effective)
