Ultima Pharmaceuticals packages this blend in a 10 ml vial holding 400 mg per ml of three testosterone esters: cypionate, decanoate, and enanthate. The company, based in the USA, has made these since 2022.

Cypionate, Decanoate, and Enanthate at 400 mg/ml

The vial carries all three esters together, each contributing to the 400 mg concentration. Testosterone cypionate and testosterone enanthate share similar release profiles, while testosterone decanoate extends further. The blend keeps all three Steroid Mix in one package rather than requiring separate ampoules or vials for each ester.

10 ml Vial Against Single-Ester Formats

Where single-ester products such as Gomeisa Labs' testosterone cypionate or testosterone enanthate each contain one compound per vial, this blend includes three in the same milliliter volume. The 10 ml format matches standard vial sizes across the catalogue, and the 400 mg strength sits above typical 200 mg or 250 mg single-ester concentrations.
