What is Masteron Propionate (Mast P)?

Drostanolone Propionate, commonly known as Masteron Propionate, was introduced for medical use in 1961 for the treatment of breast cancer in women. Although it is no longer marketed commercially, it is a common androgen and anabolic steroid used among bodybuilders during their cutting cycles to harden the look of muscles. It is derived from DHT which has been structurally altered by the addition of a methyl group at the C2 position. This means that drostanolone is not a substrate for aromatase, and therefore, cannot be aromatized into estrogenic metabolites, producing no estrogenic activity. This makes it an ideal choice for athletes struggling with estrogenic side effects such as gynecomastia and fluid retention, as Masteron could reduce the effects caused by other drugs in your stack, reducing the need for an anti-estrogen. It is also not known to pose a risk of hepatotoxicity.

Masteron Propionate has a very short half-life of approximately 1-2 days. This means that it reaches peak levels much quicker than the enanthate ester and must be injected much more frequently in order to maintain stable blood serum levels. It has a much lower androgenic rating compared to testosterone, resulting in less of a risk of virilization. It carries an anabolic/androgenic rating of 62/25 respectively. It may be used by women in low doses, as it produces considerably less virilization when compared to equal doses of testosterone propionate. However, female users must be aware that mild virilization, including acne, deepening of voice, hair loss, etc., could manifest with long-term therapy. Hair loss is a possible side effect in users with a history of male-pattern baldness.

Although Masteron Propionate is not well-known for promoting lean muscle gains, it does promote significant boosts in strength and is well known for enhancing metabolic rate. It is an exceptional cutting agent for users wanting a harder, dryer look. Some of the benefits of Mast P include:
– Ability to enhance fat loss and promote lipolysis
– Produces moderate strength gains, recovery, and endurance
– Carries anti-estrogenic effects
– Exceptional cutting agent to produce a hard, dry look in the muscles
– Best to use pre-show in users under 10% BF and at the end of cutting cycles

What is the recommended dosage?

The recommended dosage of Masteron Propionate varies widely depending on who you talk to. In our opinion, a sensible dosage for most athletes is between 200-600mg per week for males. A typical cycle will last 8-12 weeks, with a maximum of 16 weeks. Female users should not exceed 200mg/week for a maximum of 6 weeks to minimize the virilization effects. It is strongly recommended that women stick to a dose in the 50-100mg/week range. For both male and female users, this dose should be divided into 3 injections/week.

What does Masteron Propionate stack well with?

Masteron and Testosterone have a symbiotic relationship and stack extremely well together for all stages of bodybuilders. A 50% test, 50% masteron cycle will give sufficient results for most users. The addition of Anavar may also be beneficial for many users, including females. For extreme results, a “Superman Stack” of 1/3 Masteron Propionate, 1/3 Testosterone Propionate, 1/3 Trenbolone Acetate can be used. This should be reserved for only the most advanced and seasoned athletes who have previously experienced the results from Masteron.
