Magnum Pharmaceuticals ships drostanolone propionate in a smaller carton than most houses do: five ampoules instead of the customary ten, each 1 ml at 100 mg/ml. A half-size box is a sensible way to see how a given manufacturer's oil behaves before committing to a full pack.
The active is an injectable DHT-derived androgen with a short propionate ester and no estrogenic conversion. Magnum is an Indian producer, and the Drostan-P name follows its house convention of prefixing every product with the brand and marking the ester with a single letter.
