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:
- Metabolic & GLP-1
- Retatrutide (IR-3RT), Tirzepatide (IR-2TZ), Semaglutide (IR-1SG), Survodutide, Cagrilintide, Mazdutide, AOD-9604, MOTS-c, 5-Amino-1MQ
- Recovery & Tissue Repair
- BPC-157, TB-500, BPC-157 + TB-500 blend
- Performance & Energy
- IGF-1 LR3
- Growth Hormone
- CJC-1295, Ipamorelin, CJC-1295 + Ipamorelin, Tesamorelin
- Skin Health & Anti-Aging
- GHK-Cu, Melanotan I, Melanotan II, GLOW, KLOW
- Gut Health & Immunity
- KPV, Thymosin Alpha-1, VIP
- Sleep & Recovery
- DSIP
- Longevity
- NAD+, Glutathione, Epitalon, SS-31
- Sexual Health
- PT-141, Oxytocin, Kisspeptin-10
- Bioregulators
- Pancragen, Prostamax, Livagen, Testagen, Thymalin
IRON sells retatrutide as IR-3RT (its description names the compound), tirzepatide as IR-2TZ (the product code reads IRONP-TRZ-US-10MG) and semaglutide as IR-1SG (its product address names the compound).
IRON’s compounds are tested by Freedom Diagnostics, and it publishes a library of 86 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. IRON Peptides accepts credit card, Apple Pay, Google Pay and pay by bank at checkout. Paying by bank takes a further 5% off at checkout.
