Sustanon is a blended testosterone preparation: four esters of the same hormone — propionate, phenylpropionate, isocaproate and decanoate — combined in one oil-based injectable to a total label strength of 250 mg.
Because it is a multi-ester blend it also appears in our Stacks section. Supplied in a sealed vial; store upright at room temperature, out of direct light, and away from children and pets.
