Sustanon (Testosterone Blend) — reference

Fixed blend of four testosterone esters with staggered release (propionate, phenylpropionate, isocaproate, decanoate).

Regulatory statusNot FDA-Approved
Published half-lifeBlend of ~1–15 days depending on ester
Evidence levelFDA label
CategoryTRT & Hormones

Regulatory status

Not FDA-Approved. Not FDA-approved in the US, though approved in many other countries. Schedule III controlled substance in the US.

Reported cautions

⚠ Worth knowing. The staggered esters make blood levels harder to interpret than a single-ester product — timing of a trough draw matters more. Model each ester separately rather than as one curve.

Pharmacokinetics

Published figures give an elimination half-life of Blend of ~1–15 days depending on ester. Mix of propionate, phenylpropionate, isocaproate, decanoate — early spike then sustained tail.

This figure is tagged FDA label in our evidence system. This figure appears in an approved product's prescribing information, which is the strongest tier in our system — a regulator-reviewed number for a specific approved product. You can see the shape this implies between doses in the Half-Life Visualizer, and compare it against every other compound in the Half-Life Data Table. Our sourcing page explains what each tier means.

Remember that an estimated curve is a model built from a population figure, not a measurement of your blood. Individual clearance varies, and for depot injections the figure describes release from the injection site rather than the compound clearing. Half-life explained →

What Peptide Plug does and does not publish

This page carries regulatory status, general context and published pharmacokinetics. It carries no dose, frequency or cycle information — that is a deliberate editorial line, because dosing is a clinical decision rather than reference data. We also do not sell, supply, source or link to vendors for any compound.
