Drostanolone propionate belongs to the dihydrotestosterone branch of androgens, which is why it does not convert to estrogen and carries a mild anti-estrogenic character of its own.
Eminence Labs supplies it as an oil-based solution for intramuscular use, boxed as ten sealed 1 ml glass ampoules at 100 mg/ml. Propionate is the short ester on this molecule, so blood levels rise and fall quickly and the compound sits with the frequent-injection androgens rather than the weekly ones. Eminence Labs is an Indian house whose injectable catalogue leans almost entirely on single-dose ampoule presentations like this one.
