Every Legendary Peptides product page carries a downloadable Certificate of Analysis from Freedom Diagnostics, an independent US lab (FreedomDiagnosticsTesting.com). Each certificate is batch-matched to a lot number and reports identity by LC-MS, purity by HPLC-UV, net peptide content, and endotoxin by an LAL assay run in duplicate under USP <85> (≤0.05 EU/mL sensitivity); it carries a per-lot accession and search code — recent certificates add a QR code — searchable at FreedomDiagnosticsTesting.com. The most recent Legendary lots extend the panel with a PCR microbial screen and a fentanyl screen, both reported as passing, and Legendary states that fentanyl screening of internationally sourced material is a standing part of its sourcing checks.
Legendary Peptides lists a US phone number and ships domestically. All products are sold for laboratory and research use only.
