Stakos is Driada Medical's three-substance injectable, pairing testosterone propionate with drostanolone propionate and trenbolone acetate in a single 10 ml vial at 150 mg per ml total concentration. Each compound shares propionate or acetate ester length, and the vial format holds enough for repeated draws from one seal.

Testosterone, Drostanolone and Trenbolone in One Vial

The blend divides 150 mg per ml across three actives: testosterone propionate supplies the androgen base, drostanolone propionate adds the masteron compound, and trenbolone acetate completes the mix. All three esters release on a similar short timeline, so the injection schedule stays consistent across the substances. The 10 ml glass vial is drawn with a needle each time rather than broken open like an ampoule. Driada Medical, based in the EU, has offered Steroid Mix since 2023.

Stakos Beside Other Short-Ester Blends

Cut Mix 150 from Ultima Pharmaceuticals carries the same three compounds at the same 150 mg concentration in a 10 ml vial, matching Stakos in composition and pack size. Where single-compound options are preferred, testosterone propionate, Tri Test Blend 350 from Gomeisa Labs, and trenbolone acetate from the same maker are each supplied as separate vials, allowing individual dosage control rather than a fixed ratio.
