Proviron (Mesterolone) Powder Muscle Building Strong Effects USP Standard CasNO.1424-00-6

 Proviron is a drug which is likely familiar to the competitive bodybuilder. The drugs abilities to both increase androgen and reduce oestrogen levels is highly sought after by a bodybuilder close to contest. Proviron is often used in higher doses in this phase, and can bump up the levels of androgens, especially useful if the likes of Winstrol and Anavar are being used which have a low androgenic nature. The increase androgen levels will bring about a dense solid look to the users physique.

       Proviron is an orally applicable androgen and dihydrotestosterone (DHT) derivative. It is sold under the brand name Proviron(as Provironum in Asia-Pacific region), by Bayer Schering Pharma (earlier by Schering). In the late 1970s and early 1980s, it was used with some success in controlled studies of men suffering from various forms of depression. Proviron is a relatively weak androgen and rarely used for replacement therapies.

       In one small scale clinical trial of depressed patients, an improvement of symptoms which included anxiety, lack of drive and desire was observed.[2] In patients with dysthymia, unipolar, and bipolar depression significant improvement was observed.[2] In this series of studies, Proviron lead to a significant decrease in LH and testosterone levels. In another study, 100 mg Proviron cypionate was administered twice monthly. With regards to plasma T levels, there was no difference between the treated vs untreated group, and baseline LH levels were minimally affected.

       Proviron had seen widespread use in bodybuilding primarily for antiestrogenic activity in anabolic steroid stacks but such use has declined after introduction of aromatase inhibitors and SERMs. Most significant benefits of current Proviron use are considered by bodybuilders to be maintaining libido off-cycle and also relatively and temporarily improving vascularity.
