Mastabold from Omega Labs delivers Drostanolone Propionate at 100 mg per ml in a 10 ml vial. This injectable format supplies the propionate ester of drostanolone, formulated for intramuscular administration. The vial holds a total volume of 10 ml, with each milliliter carrying the stated concentration.

Drostanolone Propionate at 100 mg/ml

The label states 100 mg of Drostanolone Propionate per milliliter. Other labs offer the same ester at this concentration, including drostanolone propionate 100mg from Crowx Labs and masteron 100 from Gomeisa Labs, while some present 150 mg or 200 mg versions. The propionate ester is a short-chain attachment that distinguishes this product structurally from enanthate-ester alternatives, which carry a longer carbon chain. Mastabold's 10 ml vial format matches the standard across most propionate listings, though count and packaging vary between manufacturers.
