NextGenPeps sells three of its metabolic compounds under coded names: GLP-RT is Retatrutide, GLP-TZ is Tirzepatide, and GLP-S is Semaglutide. We list each under both its compound name and its code — “Retatrutide (GLP-RT)” — because on this store the code is the only term that finds the product: searching nextgenpeps.com for “Retatrutide” returns nothing at all, while “GLP-RT” returns the vial.
That mapping comes from the vendor’s own product data rather than from a certificate: each coded product carries the plain compound name in the store’s own tagging fields. It is the vendor stating what the product is, which is a weaker record than a CAS number printed on a Certificate of Analysis and a stronger one than the SKU numbering, which we never decode from. Worth knowing alongside it: the GLP-TZ product description on NextGenPeps’ own site describes the mechanism of GLP-2, a different and unrelated hormone. The tagging is right and that paragraph is wrong, and neither is a certificate.
NextGenPeps publishes a Certificate of Analysis library at nextgenpeps.com/coa-library, open without an account, with a purity certificate and an endotoxin certificate for each compound it covers. The certificates are native text PDFs issued by BioRegen to NextgenPeps, signed by the laboratory’s analyst and carrying BioRegen’s own contact address and verification URL on their face, so the check runs against the laboratory rather than against the vendor. The compound name, its CAS number and the reported purity all read straight out of the document. The library now covers the three coded GLP products too — the most expensive items NextGenPeps sells — with dedicated certificates for Retatrutide, Tirzepatide and Cagrilintide, each naming the compound in plain text. The one limit still worth stating: the library covers only a minority of the catalog.
Three of those certificates have been opened — BPC-157 5mg, Tirzepatide 10mg and Retatrutide 10mg — and all three are BioRegen documents, which is why BioRegen is now carried as a verified laboratory. Janoshik is kept on record from an earlier certificate read but appears on none of the three, so it is reported as history rather than as a description of what the library holds now. No accreditation is claimed for either laboratory, because neither prints one on the certificates reviewed.
One point of identity, because the names collide. NextGenPeps is not NextGen Peptides (ngpeptide.com), a separate vendor we also cover at its own discount-code page. They are different companies on different platforms with different laboratories, and NextGenPeps’ own navigation shortens its name in a way that makes the two easy to confuse. Everything on this page describes nextgenpeps.com. All products are sold for laboratory and research use only.
