Most anti-estrogen drugs are primarily designed to keep estrogen levels in check. Mesterolone, however, does more than just that. Popularly known as Proviron, this anti-estrogen is highly potent and synthetic. It not only keeps estrogen and testosterone levels in check but also increases muscles’ firmness and improves libido. It is especially popular with steroid users during their cutting cycles. There are several manufacturers and brands of Proviron, and the most popular ones include MyoGen (Provigen), Alpha Pharma (Provibol), Provibolic (Cooper Pharma) and A-tech Labs (Proviron).
