Also known as
Sustanon Composite Mix
Sustanon Composite Mix refers to a multi-ester testosterone preparation. This shop lists two injectable options: one from Prime and one from Magnus, both containing 250 mg of testosterone per 10 ml vial. The blend includes testosterone propionate, phenylpropionate, isocaproate, and decanoate. Athletes typically run this product for its combined short- and long-acting ester profile.
Composition and Esters
The Sustanon Composite Mix contains four distinct testosterone esters. This combination results in a rapid initial release followed by sustained delivery over several days. The short-acting propionate and phenylpropionate components drive early peaks, while the longer isocaproate and decanoate maintain stable levels. Users report this profile supports consistent anabolic activity throughout the dosing interval.
Product Options
Buyers can choose between the Prime-branded and Magnus-branded Sustanon Composite Mix. Both products share an identical 10 ml/250 mg specification. The only difference is the manufacturer. Athletes should verify their preferred brand based on availability and personal experience, as the underlying compound and dosing schedule remain consistent across both listings.
