Legendary Peptides sells research-only singles and blends with prices on the product pages, including house codes GLP2 (T) for tirzepatide and GLP3 (R) for retatrutide, plus GLOW/KLOW, BPC/TB, CJC/IPA, and Tesamorelin/Ipamorelin blends. Its public certificate library contains Freedom Diagnostics reports; PeptideBenchmark checks printed Search Codes at Freedom and confirms the Legendary Peptides client name. Current certificate-to-catalog relationships are counted only where independently confirmed. Ten-vial kits, bacteriostatic water, LIPO-C+, and L-Carnitine stay outside the retail single-vial board.
Readers who want a U.S.-shipped catalog with house GLP codes mapped on the pricing board and a public Freedom Diagnostics certificate library with individually checked laboratory report identities.
GLP2 (T) and GLP3 (R) are house codes for tirzepatide and retatrutide; Tesa is tesamorelin. Ten-vial kits, bacteriostatic water, LIPO-C+, and L-Carnitine stay off the peptide $/mg board. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Checked August 19, 2026Public Freedom Diagnostics certificate library with provider verification
The public certificate library includes Freedom Diagnostics reports verified under the Legendary Peptides client name. Reports typically support identity, HPLC purity, net content, and endotoxin for the named sample. We have not verified every current catalog relationship; an unresolved relationship does not mean the vendor lacks a certificate link. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
