Mast P 100 is an injectable steroid which contains the hormone drostanolone propionate. The preparation comes in vial of 10 ml and contains 100 mg of drostanolone propionate per ml. Drostanolone propionate is most commonly used by bodybuilders who are in the "cutting" phase of their training and dieting. While only mildly anabolic, mast p 100 extremely androgenic and because of this, brings about a very pronounced amount of hardness and definition to the muscles. On top of this, mast p 100 is also noted as being an effective estrogen blocker, and also binds to shgb, making it possible for other steroids being used to bind more easily to their respective receptors, thus making their presence in the body much more effective.
