Mastabol 100 (MASTERON) (100mg/ml 10 ml)

Mastabol is a synthetic derivative of dihydrotestosterone, producing an anabolic effect by promoting protein synthesis, as well as creating a positive nitrogen balance in humans. Since it is a derivative of dihydrotestosterone, dromastolone di-propionate does not aromatize in any dosage and thus it cannot be converted into estrogen.
