Masteron Propionate

Masteron Propionate is the propionate ester of drostanolone, a DHT-derived anabolic steroid that does not aromatise into oestrogen. Users run it mainly in cutting phases because it hardens muscle bellies, sharpens vascularity and gives a drier look, and this effect shows best on a physique that is already lean. Beligas Pharmaceuticals produces this version at 100mg/ml.

Because propionate is a short ester, it clears the body quickly, so it is injected frequently rather than once a week. A common approach is 300mg per week split into two equal injections, for example Monday and Thursday, staying at or below 400mg per week and running the compound for 8 to 10 weeks. This is general usage information, not medical advice, and any research protocol should follow bloodwork and guidance from a licensed doctor.

No. Drostanolone is a non-aromatising DHT compound, so it will not raise oestrogen on its own and does not require an AI to control gyno or water retention from this compound specifically. Anastrozole is still relevant if it is being run alongside testosterone at higher doses, since that base compound does aromatise.

Reported effects include hair loss in those already predisposed, prostate enlargement symptoms, a negative pull on HDL cholesterol, and mood changes or aggression in some users. Baseline and follow-up bloodwork covering testosterone, oestradiol, lipids, liver enzymes and PSA is recommended to track these changes. Masteron also suppresses natural testosterone production, so a testosterone base and a proper PCT afterwards, such as nolvadex 40mg daily for two weeks then 20mg for two more, or clomid 50mg daily for four weeks, are standard practice.

Both are the same drostanolone hormone, so the effects on hardness and vascularity are identical. The difference is the ester: propionate is shorter-acting and needs injections two to three times a week, while enanthate is a longer ester dosed once or twice weekly with a slower release. Propionate is often preferred nearer the end of a cutting cycle or in a contest-prep context where more frequent, finer dose control is useful.
