Primobolan, also known as Methenolone Acetate, is derived from DHT and then structurally altered. It is partly anabolic and partly androgenic, which means that it has both steroid and anti-estrogen benefits. It is mainly used as a steroid for boosting the development of lean muscles. However, as an anti-estrogen, it can be used to balance estrogen and hormone levels during steroid cutting cycles. It is also important to note that it is not toxic as it is classified as a C-17A compound.
