Masteron (Drostanolone Propionate) is an anabolic androgenic steroid. It is known to be quite anabolic androgenic and mild. It is not aromatic and has similar properties to dihydrotestosterone. Breast cancer has been successfully used as a patient, but it offers safer options because of the high risk of virility. Masteron is not used clinically for weight gain (as with most steroids), making a very unique steroid in this respect. Unfortunately, many of the information in Masteron’s medical journals do not focus on weight loss, power gain or even fat loss.
