Supra-Testosterone is a branded version of a testosterone blend composed of four different testosterone esters: Testosterone Propionate, Testosterone Phenylpropionate, Testosterone Isocaproate, and Testosterone Decanoate. It is widely recognized in bodybuilding circles and is often known under the brand name Sustanon 400. The primary difference between Sustanon 400 and Supra-Testosterone lies in their branding, manufacturer, and pricing, with no significant differences in the formulations.

This injectable product features a combination of four androgenic anabolic steroids (AAS), each with distinct release times:

• 60 mg of Testosterone Propionate
• 120 mg of Testosterone Phenylpropionate
• 120 mg of Testosterone Isocaproate
• 100 mg of Testosterone Decanoate

The total dose is 400 mg. Each ester provides testosterone at varying rates, allowing for both immediate and sustained release. The short-acting esters deliver testosterone quickly, while the long-acting esters ensure a prolonged effect.
