Masteron is a powerful anabolic/androgenic steroid derived from DHT that was designed to fight certain forms of breast cancer. It is used by bodybuilders as a bulking and cutting agent, as well as an ancillary drug to combat estrogenic side effects like water-retention. Its toxicity to the liver is very low, although side effects such as acne, hair loss and prostrate enlargement are common. Masteron Propionate has a release time of between 2-3 days. It is typically injected every other day. Dosages are around 500mg per week.
