Mesterolone Powder (Proviron)




Mesterolone Powder (Proviron)

Mesterolone Powder (Proviron) is an orally applicable androgen and dihydrotestosterone (DHT) derivative. It is sold under the brand name Proviron (as Provironum in Asia-Pacific region). Mesterolone lead to a significant decrease in LH and testosterone levels. In another study, 100 mg mesterolone cipionate 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


Mesterolone 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 Mesterolone use are considered by bodybuilders to be maintaining libido off-cycle and also relatively and temporarily improving vascularity.
