5. Usage: Proviron is helpful in stacks because of its unique ability to keep the body from turning testosterone into estrogen, thus giving the testosterone a better anabolic effect. Also, Proviron can help boost the potency of testosterone in the body by freeing testosterone from its binding to sex hormone-binding globulin (SHBG).
Mesterolone 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.
Mesterolone dosage: Doses between 25 and 250 mg per day are used with no adverse effects. 50 mg per day is usually sufficient to be effective in each of the four cases we mentioned.
