Ultima Pharmaceuticals supplies Supertest 450 as a 10 ml vial carrying 450 mg per ml of blended testosterone. The formulation combines acetate, propionate, phenylpropionate, cypionate and decanoate esters in one injection solution.

Acetate, Propionate, Phenylpropionate, Cypionate and Decanoate in One Vial

Each milliliter draws from five esters: testosterone acetate, testosterone propionate, testosterone phenylpropionate, testosterone cypionate and testosterone decanoate. The 450 mg concentration stacks all five into a single vial, where shorter esters sit alongside longer-chain variants. Compare that to single-ester Tri Test Blend 350 from Gomeisa Labs at 200 mg per ml, or to Tri Test 400 Blend at 100 mg per ml from the same maker.

450 mg Per Milliliter Across 10 ml

The vial holds 10 ml of oil solution, each milliliter dosed at 450 mg. That places total content at 4,500 mg per vial. Multi-ester blends at this concentration require careful measurement due to the viscosity of high-strength oil. Ultima Pharmaceuticals, a USA-based company making these since 2022, packages the blend in standard injection vials compatible with luer-lock syringes.
