Eight assays. One peptide receipt.
A single chromatogram can be forged. A single m/z can be misassigned. We require both to agree on every peptide we sign — plus the dose-accuracy markers (NPC, TFA), the GLP-1-specific impurity scan, and the endotoxin / sterility data injectable-grade buyers ask for.
Published. Per-test.
No quote calls.
Every assay a la carte, every panel bundled. Bulk discount at 5+ samples. Prices below reflect a single-compound submission.

Where peptide COAs fail.
Synthesis byproducts, counter-ion mismanagement, storage degradation, and process-water endotoxin account for most flagged peptide lots. Knowing where the risk concentrates is the first half of the testing scope.
USP, ICH, ISO 17025 Aligned, 21 CFR Part 11.
Research peptide testing operates outside the FDA finished-drug regulatory loop, but USP and ICH standards still anchor the analytical methods. Here's what we map to.
USP <85> LAL methodology for endotoxin quantitation. Kinetic chromogenic on the Charles River Endosafe stack with documented inhibition / enhancement validation. Required for any peptide intended for injectable / parenteral use.
Direct inoculation or membrane filtration into fluid thioglycolate (anaerobic / facultative) and soybean-casein digest (aerobic / fungal) media. 14-day incubation. Required for terminally-sterilized injectable peptides and APIs.
Permitted Daily Exposure limits for Pb, Cd, As, Hg in pharmaceutical-grade material. Available as the heavy-metal impurity scan add-on or bundled into the Vendor Full QC.
ICH thresholds for reporting, identification, and qualification of impurities. Our HPLC method reports any impurity peak above 0.1 % area; impurities above 0.5 % get individual MS identification.
Instrument software audit trails, raw chromatograms, and mass spectra retained per 21 CFR Part 11-style data-integrity principles. Available to the client of record on request.
HPLC purity % is the fraction of the main peak among all peptide-containing material. NPC is the fraction of total dry mass that is actually peptide — the rest is TFA / acetate counter-ions, water, and salts. NPC is typically lower than purity %. Both matter for dose accuracy: a 10 mg vial at 99 % purity but 78 % NPC contains 7.8 mg of actual peptide.
Pair this panel with —
USP <85> bacterial endotoxin for injectable-grade research peptides — bundles onto the peptide COA.
USP <71> sterility for terminally-sterilized injectable peptide vials and APIs.
Semaglutide, Tirzepatide, Retatrutide — mass-confirmed identity, purity, and Net Peptide Content on one public COA.
