Peer narratives
★★★★★“Chromatograms on the latest lot matched our in-house retention-time standards within instrumental variance. Documentation was sufficient for our IBC submission package.”
★★★★★“We run duplicate HPLC on arrival; three consecutive orders from Premium Peptides Lab showed co-elution of the principal peak with our reference material at 99.2–99.6%.”
★★★★★“The COA structure is what our QA group expects: method, instrument ID, chromatogram, and integrator report—no ambiguous screenshots.”
