Beligas Pharma supplies this blend under the name Tren Test Mast Short 150mg, packaged as a 10 ml vial carrying 150 mg per ml. The formulation brings together trenbolone acetate, testosterone enanthate, and drostanolone propionate in one injection.

Three Compounds at 150 mg/ml

Each ml delivers a portion of all three substances at the stated concentration. The vial holds enough solution for multiple administrations without opening a second container. Beligas Pharma, based in Belgium and producing these blends since 2020, manufactures this line. Where single-ester options such as masteron 100 or trenbolone acetate vials separate each compound, this presentation combines them at a fixed ratio.

Vial Format Beside Ampoule Alternatives

The 10 ml vial differs from ampoule formats in volume and access: one rubber stopper serves repeated draws, while a OmniMass seals a smaller quantity meant for single use. Blends at higher concentrations exist—some reach 400 mg/ml across four or five esters—but this specification keeps the total at 150 mg per ml across the three listed.
