BioLongevity Labs is a US-based research-peptide supplier with a catalog that leans toward specialty and longevity compounds rather than the mainstream healing peptides most vendors lead with. This review covers how they operate, what they're known for, and the four vendors we track day to day for pricing, COA verification, and discounts on the same compounds.
Who Is BioLongevity Labs?
BioLongevity Labs runs a US-based research-peptide storefront with COA documentation on the products they ship. Their catalog stands out for its specialty and nootropic coverage — melanocortin peptides (PT-141, Melanotan I), nootropics (Semax, Selank), sleep peptides (DSIP), reproductive and neuro peptides (Kisspeptin, Oxytocin, VIP), immune peptides (Thymulin), and metabolic compounds (5-Amino-1MQ) — alongside standard growth-hormone and performance peptides. Catalogs change frequently, so check the vendor's own site for current availability.
COA & Testing
BioLongevity provides certificate-of-analysis documentation on the products they ship. Third-party verification is the baseline any research-peptide buyer should expect — what matters most is that the COA is current and corresponds to the batch your vial came from, which is a useful standard to hold any vendor to.
The Vendors We Track and Recommend
For live pricing, in-stock status, COA verification, and active discount codes — across both mainstream and specialty compounds — these are the four vendors we keep current and point readers to. Each has a distinct catalog strength.
EZ Peptides runs one of the broadest catalogs we track, and it's the strongest fit for GLP-1 buyers — multi-dose GLP-1 kits (including the large retatrutide kit) alongside a wide range of single compounds and pre-mixed blends. COAs are QR-linked per product, and the permanent 10% discount (code ) makes them a consistent value across the catalog.
Ion Peptide is the closest match for BioLongevity's specialty side — beyond standard injectables, Ion carries sublingual drops, pre-mixed nasal sprays, and topical formats, including Semax and Selank in non-injection forms and a GHK-Cu balm. Each product carries its own COA.
Nura Peptide leans into the weight-management and mitochondrial categories — GLP-1s like tirzepatide and retatrutide, SS-31 and MOTS-C, plus a copper-peptide and exosome skincare line that most research vendors don't offer.
Glacier Aminos is the specialist of the group, and a strong fit for the metabolic and blend side of BioLongevity's catalog. Their standout is 5-Amino-1MQ, and they carry one of the deeper pre-mixed blend lineups we track (Wolverine, GLOW, KLOW, CJC-1295 + Ipamorelin, Tesamorelin + Ipamorelin, and a Retatrutide + Cagrilintide blend), plus strong coverage on tesamorelin and MOTS-C.
