The whole process, start to finish, and exactly what you get back.
Choose your compound and services on the order page. You’ll get an order reference and submission details.
Drop the vial and your reference into plain packaging and mail it in. No product names on the outside.
HPLC purity, LC-MS identity, and quantification against calibrated standards — reviewed by an analyst before release.
Your certificate posts to the public registry with a unique ID that anyone can check.
The sample is dissolved and injected onto a reverse-phase C18 column. A water/acetonitrile gradient (0.1% TFA) separates the target peptide from its impurities; UV detection at 214 nm records every peak.
The eluent flows into a mass spectrometer. The measured exact mass is compared against the theoretical mass of the claimed peptide — the definitive check that it’s the right molecule.
A calibration curve from a certified reference standard converts peak area into an absolute amount, so we can state how many milligrams are truly in the vial versus the label claim.
Each COA carries a unique ID, the compound and submitter, the three headline numbers, the instrument methods used, and analyst notes. We flag results three ways:
Correct identity, high purity, and content within tolerance of the label claim.
Right molecule and acceptable purity, but content is meaningfully off the label claim (e.g. an under-filled vial).
Low purity, significant impurities, or an identity that doesn’t match the claim.
