Product Information

Maste K 1000 contains Drostanolone Propionate, a short-acting ester of drostanolone formulated for intramuscular administration. Compared with longer esters such as drostanolone enanthate, the propionate ester has a shorter duration of action. Scientific literature has evaluated drostanolone propionate for its pharmacokinetic characteristics, androgen receptor binding, metabolism, and biological activity. These findings do not establish safety or effectiveness for unapproved human uses.

The designation “1000” is part of the manufacturer’s product name and does not by itself identify the concentration, vial size, or total content. Users should verify the exact strength (mg/mL), vial volume, and formulation from the product label or the manufacturer’s official documentation before use.
