Primobolan – Methenolone Acetate, also popularly known as Primobolan, is a structurally altered form of DHT. It is composed of both anabolic and androgenic properties, which makes it partly useful as an anti-estrogen. Its main benefit is supporting the development of lean muscles and boosting periodic energy release. Other benefits include suppressing production of estrogen and aiding in muscle and tissue recovery.
Primobolan is not similar to C-17A compounds, meaning that it is not toxic to the liver. Popular brands include Primo and Methenolone, while leading manufacturers include Alpha Pharma, Cooper Pharma and Hilma Pharma.
