Ultima Pharmaceuticals offers Test/EQ 400 Mix as a 10 ml vial delivering 400 mg per ml of two substances: testosterone enanthate and boldenone undecylenate. Each milliliter carries both compounds in a fixed ratio, supplied as an injectable solution.

Testosterone Enanthate and Boldenone Undecylenate at 400 mg/ml

The vial holds testosterone enanthate alongside boldenone undecylenate, each contributing to the 400 mg total concentration. Gomeisa Labs lists Stakos separately at 250 mg/ml in 10 ml, and Tremilad at 200 mg/ml in the same volume. This blend delivers both substances in one draw, where single-compound vials require separate administration. Ultima Pharmaceuticals, based in the USA, has made injectable steroids for bodybuilding since 2022.

10 ml Vial, 400 mg per ml

The pack is a single vial holding 10 ml total. At 400 mg per ml, the concentration is higher than the 200 mg and 250 mg single-substance options from other labs. The form is injection, and the vial cap allows multiple draws over repeated use.
