Masterone Propionate (Mast P) is a synthetic anabolic androgenic steroid (AAS) derived from dihydrotestosterone (DHT). It works by binding to androgen receptors in the body, resulting in increased muscle mass and strength and decreased body fat.

Masteron propionate has a typical half-life of about 2–3 days. This means that it needs to be administered more frequently than other AAS with longer half-lives.

The recommended dose of Masterlon Propionate depends on the individual’s goals and his AAS experience. The usual range is 300–400 mg per week for men and 50–150 mg per week for women. It is important to note that the use of AAS containing Masterlon Propionate is not recommended for persons under the age of 21 and should only be used under the supervision of a healthcare professional.

Possible side effects of Masterlon Propionate include acne, hair loss, increased body hair growth, and adverse effects on cholesterol levels. Additionally, there may be suppression of natural testosterone production and other side effects associated with anabolic steroid use such as gynecomastia and testicular atrophy.
