Masteron is a new product made by Golden Triangle 2008.

Mastagen 100 (dromostanolone propionate or drostanolone propionate), is a popular steroid among competitive bodybuilders. It is commonly used in contest preparation for many reasons. The androgenic effect of this steroid can cause a noticeable improvement in muscle density and hardness which can help the bodybuilder obtain the "ripped" look if his bodyfat percentage is low enough. The androgenic effect is also crucial because it helps to provide sufficient "kick" or "drive" for intense training when an athlete has lowered his caloric intake for contest preparation.
