Sustanon 250 · Four-Ester Testosterone Blend
Sustanon 250
Sustanon 250 combines four testosterone esters with different durations of action in one injection. It is commonly used for testosterone replacement therapy (TRT), muscle building and bodybuilding. The mixed-ester formula is what makes Sustanon different from a single-ester testosterone product.[1][2]

What makes Sustanon different
Four Testosterone Esters
Sustanon combines Testosterone Propionate, Testosterone Phenylpropionate, Testosterone Isocaproate and Testosterone Decanoate in a single 250mg/ml blend.
Official Sustanon product information confirms that the four esters have different durations of action and are converted to testosterone after entering the circulation.[1]
Technical breakdown
What Is in Sustanon 250?
| Testosterone Ester | Amount Per 1ml |
|---|---|
| Testosterone Propionate | 30mg |
| Testosterone Phenylpropionate | 60mg |
| Testosterone Isocaproate | 60mg |
| Testosterone Decanoate | 100mg |
That exact 30mg + 60mg + 60mg + 100mg composition is also the registered Sustanon 250 formula listed by official medicine regulators.[1][2]
In pharmacokinetic data for Sustanon 250, testosterone levels peak roughly 24–48 hours after an injection and then decline gradually, with the longer ester components extending the release profile.[1]

How the blend works
Why Sustanon Uses Four Esters
The four-esters formula gives Sustanon a combined release profile rather than relying on one testosterone ester alone. The shorter-duration components contribute earlier in the release curve, while Testosterone Decanoate extends the longer end of the profile.
Official pharmacokinetic data for Sustanon 250 reports peak testosterone levels around 24–48 hours after a single injection, with levels returning toward the lower end of the normal male range over approximately three weeks.[1]
For clients who specifically want a mixed-ester testosterone rather than a single-ester product, this four-ester formula is the main reason to choose Sustanon 250.
