Six of the seven vendors we compared in September list AOD-9604, and PSPeptides documents it best: its August 2026 certificate names North American Diagnostics, gives a batch number and reports 5.03 mg measured in a 5 mg vial, with endotoxin, sterility and heavy metals reports alongside. NextGenPeps names Janoshik on an April 2026 report. Swiss Chems doesn't sell AOD-9604, Peptide Plugs showed it sold out, and no vendor has independent Finnrick data.
Notice: Research peptides are sold for in-vitro laboratory research only. They are not FDA-approved, not for human or animal consumption, and this page is not medical advice.
Our criterion: an AOD-9604-specific COA with a named lab and lot number beats a generic "third-party tested" claim. We don't test products; we check what each vendor publishes.

Single-vial prices shown on September 26, 2026, including any displayed sale price. $/mg is price divided by labeled mg. Vendors appear in our editors' order, which isn't sorted by score.

Notes on the table:
- American Peptides: the product page lists one 5 mg size. Its COA page shows lot AOD5-0803 and a superseded lot, with no lab or purity shown.
- NextGenPeps: the product page showed $42, down from $52. Its COA library names Janoshik for the April 2026 report.
- PSPeptides: the shop listing marked it "Low stock." The August certificate reports 99.94% purity and 5.03 mg measured, by HPLC with mass spectrometry. The product page also links endotoxin, sterility and heavy metals reports.
- Ascension Peptides: the product page lists three batches: Kovera Labs (May 2026) and MZ Biolabs (April 2026 and November 2025), with no purity shown on the page (checked September 26, 2026). Regular price is $74.99.
- Peptide Plugs: the shop listing showed "AOD-9604 2mg" as sold out; the product page offers 2 and 5 mg "from $30" with no stock count. Its displayed certificate reports 99.04% purity but 4.36 mg measured against a 5 mg label (-12.8%). The COA page lists a July 24, 2026 test of the 2 mg vial at 99.16% and 1.93 mg.
- Swiss Chems: a site search for AOD returned no products, and it isn't in the peptide catalog.
- Alpha Pro Peptides: the testing page lists lot AP-AD5-0426 at 99.44% purity and 6.32 mg measured, 26% over the 5 mg label. We couldn't open the PDF to confirm the lab.
- Licensed Peptides (added to our list September 28, 2026; not in the table): its shop listed AOD-9604 as sold out (shop, checked September 28, 2026). We didn't review an AOD-9604 report from it. Review
What is AOD-9604?
AOD-9604 is a synthetic, modified fragment from the C-terminal region of human growth hormone (residues 177-191), described in early papers as a modified C-terminal fragment of hGH. It was studied mainly in obese mouse and rat models of lipid metabolism. Anti-doping labs have also published methods for its detection and in vitro metabolism.
How to check an AOD-9604 COA
- Match the lot and the size. Peptide Plugs shows a 5 mg certificate on a page whose shop listing names a 2 mg vial.
- Compare measured content to the label. Results here ranged from 4.36 mg to 6.32 mg for 5 mg labels, a wide spread for concentration math.
- Read the lab name on the PDF, then look the lab up.
- Check identity by mass spectrometry, since AOD-9604 is close in sequence to other hGH fragments.

Independent test data
None of the seven vendors we compared had independent Finnrick results for AOD-9604 on September 26, 2026. Licensed Peptides, which we added on September 28, 2026, has no Finnrick profile. Finnrick lists ten tests for Swiss Chems, covering BPC-157, ipamorelin and CJC-1295 only, and the other six vendors we compared have no Finnrick tests. Every certificate above was commissioned by the vendor, which chooses the sample it sends. More on community testing: what is Finnrick?

Bottom line
For AOD-9604, PSPeptides has the most complete recent documentation and the lowest price per mg among in-stock vendors, though its blog publishes human dosing guides, which we count against it. NextGenPeps names Janoshik but shows no lot. Peptide Plugs names its lab but was sold out, and its displayed certificate came in under label. Ascension shows no purity on the page, Alpha Pro's lab couldn't be confirmed, and American Peptides doesn't show the lab.
