AOD-9604 is a synthetic peptide corresponding to a modified fragment of the C-terminal region of human growth hormone (hGH). It is supplied lyophilised as a research compound for in vitro laboratory study only.

What AOD-9604 is

AOD-9604 is based on the C-terminal 176-191 region of the human growth hormone molecule, with a modification, and is a much shorter peptide than full hGH. It is manufactured and studied as a distinct research compound, not as growth hormone.

Its sequence is confirmed by mass spectrometry and its purity measured by HPLC, so each batch can be reported on an independent Certificate of Analysis.

Where AOD-9604 appears in research

In the research literature, AOD-9604 is studied in metabolic research models. This describes the research domain in which the compound appears, not a claim of any effect. AOD-9604 is not a medicine, supplement or cosmetic, and is not approved for human or veterinary use.

How AOD-9604 should be tested

Quality is a matter of evidence, not the label. A credible supplier tests every batch at an independent laboratory: HPLC measures purity as a percentage (commonly to a ≥99% benchmark), and mass spectrometry confirms the compound’s identity.

The result should be a batch-specific Certificate of Analysis you can verify at source. Learn how to read a COA, or see BioHack London’s independent AOD-9604 reports.

Storage, handling and reconstitution

Lyophilised (freeze-dried) AOD-9604 is generally kept cool, dry and out of light. Reconstitution — dissolving it in a suitable solvent such as bacteriostatic water — is done immediately before laboratory use, and the reconstituted solution is typically refrigerated and used within a limited period.

Our reconstitution calculator helps work out solvent volumes, and bacteriostatic water is available in the range.

AOD-9604: frequently asked questions

What is AOD-9604?

AOD-9604 is a synthetic peptide corresponding to a modified fragment of the C-terminal region (residues 176-191) of human growth hormone. It is supplied as a lyophilised research compound for in vitro laboratory research use only.

Is AOD-9604 the same as growth hormone?

No. AOD-9604 is a short modified fragment of the C-terminal region of the growth hormone molecule, not the whole hormone. It is studied as a distinct research compound.

How is AOD-9604 tested?

A credible supplier tests each batch at an independent laboratory — HPLC for purity (commonly to a ≥99% benchmark) and mass spectrometry to confirm identity — and publishes a batch-specific Certificate of Analysis you can verify at source.

Is AOD-9604 for human use?

No. AOD-9604 is supplied strictly for in vitro laboratory research. It is not for human or animal consumption and is not intended to diagnose, treat, cure or prevent any condition. Purchasers must be 18 or over.
