Drostanolone P

This is Masteron Propionate, a DHT-derived injectable steroid supplied in ampoules at 100mg/ml. It carries a short propionate ester, so it enters the bloodstream quickly and clears quickly too. It does not convert to oestrogen, which is why it is valued for a hard, dry look rather than for adding size.

Because the propionate ester is short-acting, it needs frequent injections, usually every other day, rather than a single weekly shot. A commonly reported range is around 300 to 400mg per week split across those injections, run for 8 to 10 weeks alongside a testosterone base. This is general usage information, not medical advice, and any protocol should be planned with bloodwork in mind.

As a strong DHT derivative, the main risks are androgenic: acne, oily skin, and accelerated hair loss in those already prone to it, plus a possible effect on the prostate. Masteron does not aromatise, so an aromatase inhibitor is not needed for the compound itself, though oestrogen from the testosterone base still needs monitoring. Natural testosterone production is suppressed, so a full post-cycle therapy is expected once the cycle ends, starting a few days after the last injection, and baseline plus follow-up bloodwork covering testosterone, oestradiol, lipids, and liver markers is sensible.

Both are the same DHT hormone and both are non-aromatising, but the ester length changes the injection schedule. The propionate version here is short-acting and needs dosing every other day to keep blood levels stable, while the enanthate version carries a longer ester and can be injected once or twice a week. Propionate is often preferred right at the end of a cut for a quicker-acting, more controllable effect, while enanthate suits a longer-term, lower-frequency schedule.

Yes, a testosterone base is standard practice since Masteron suppresses natural testosterone output and is not intended to be run alone. Masteron itself is best added to an already lean physique in the closing weeks of a cutting cycle, where it firms up conditioning rather than building new muscle. PCT support is required afterwards to help restore normal hormone production.
