Testosterone is the hormone the whole anabolic-androgenic class descends from, and Magnum Test-Prop 100 offers it in its fastest common ester form. Magnum Pharmaceuticals supplies the oil in ten ampoules of 1 ml, 100 mg per millilitre.
Propionate's short chain means the compound never builds a long-lasting depot. Products based on it are described as fast in onset and brief in action, in contrast with enanthate, cypionate or undecanoate, where release is spread across a much wider window. The ampoule format here means each unit is opened fresh at the point of use.
