Drostanolone propionate, by Asia Pharma.

Masteron, or drostanolone propionate, is a popular steroid among competitive bodybuilders. 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 of this steroid 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.

Masteron can also be used successfully by bodybuilders preparing for a drug-tested show. The substance drostanolone propionate is fast acting and quickly broken down. The athlete can therefore use Masteron up to about ten days before a drug test.

Effective dosage: The average dosage of Masteron is 100 mg injected every other day. It is best to inject Masteron every 2-3 days because it has a short duration of effect. Popular steroids stacked with Masteron include Parabolan(trenbolone hexahydrobencylcarbonate), Winstrol(stanozolol), and oxandrolone.

Side effects: Masteron is not hepatoxic so liver damage is unlikely. Estrogen levels remain low, water and salt retention do not occur so gynocomastia problems are reduced to zero with this drug. Main problems however are hair loss and acne since dihydrotestosterone is highly to the skin's androgen receptor.
