Drostanolone Propionate - Masteron is commonly used in contest preparation for many reasons. To begin with, Drostanolone Propionate is a derivative of DHT (dihydrotestosterone), and therefore, it will not aromatize into estrogen. Competing bodybuilders find this extremely beneficial because aromatization typically causes excess water retention which may give the muscles a smooth appearance. Another advantage of Masteron is its strong androgenic component. The androgenic effect can cause a noticeable improvement in muscle density and hardness which can help the bodybuilder obtain the *ripped* look if his body fat 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. It can also be used successfully by bodybuilders preparing for a drug-tested show. The substance is fast acting and quickly broken down. The athlete can therefore use Masteron up to about ten days before a drug test. The average dosage of Drostanolone Propionate is 100 mg injected every other day. It is best to inject it every 2-3 days because it has a short duration of effect. Popular steroids stacked with Drostanolone Propionate include Parabolan (trenbolone hexahydrobencylcarbonate), Winstrol (Stanozolol), and Anavar. Athletes rarely experience any side effects with this drug. It is not hepatoxic, and gynecomastia should not be a concern since it does not convert into estrogen.
