IRON Peptides (ironpeptides.is) is a US-based research-compound supplier. The thing worth knowing first is how its certificates check out: each one carries a search code, and that code resolves on the testing laboratory’s own website rather than only on IRON’s. A reader can confirm a certificate at the lab instead of taking the vendor’s word for it. Compounds by research area:

IRON labels its GLP-class metabolic compounds with coded names on an IR-1/2/3 tier convention, and two of the three decode from IRON’s own product data rather than from the convention: the IR-3RT listing names Retatrutide in its own description, and IR-2TZ carries the product code IRONP-TRZ-US-10MG, identifying Tirzepatide. IR-1SG is listed at a Semaglutide-identifying product address. We list each under both its compound name and its code — “Retatrutide (IR-3RT)” — so a reader searching IRON’s store for the coded name still lands on the right compound.
IRON’s compounds are tested by Freedom Diagnostics, and it publishes a library of 20 certificates. Each certificate covers identity, purity, net peptide content, and appearance, with the chemical analysis performed by HPLC with UV detection coupled to mass spectrometry. Net peptide content is measured rather than assumed — the certificate we reviewed reports 11.66 mg in a 10 mg vial.
The basis for that is worth setting out, because it is what separates a certificate a reader can check from one they cannot. Every IRON certificate prints a search code. We took one — IRON2510230085, a Cagrilintide lot — and resolved it directly on Freedom Diagnostics’ own domain, which returned the laboratory’s own copy of the report. Its contents match the file IRON publishes exactly: same lot, same measured content, same 99.834% purity result. The check runs against the laboratory rather than against the vendor, and it is a check any reader can repeat.
Two points of context. Freedom Diagnostics does not print a laboratory accreditation on these certificates, so none is claimed here — the strength of the record is the independent, externally verifiable check on the lab’s own domain. And the certificates are published as a library rather than one per batch, which is why this page describes them that way. IRON is US-based. All products are sold for laboratory and research use only.
