Lab Tests · COA library
Every batch, independently verified.
A sample from every production batch is sent to a third-party analytical laboratory. The published Certificate of Analysis covers identity, purity, and method — match it to the batch number printed on your vial.
Recent reports
Published Certificates of Analysis
All reports are from a single accredited third-party HPLC laboratory. Reports are archived for two years and remain available even after a batch sells out.
Methodology
What each report covers
Standard panel for every peptide batch — identity, purity, residual solvent, and microbial.
Identity by mass spectrometry
Confirms the material in the vial is the compound on the label, matched against a reference standard by intact-mass and fragmentation pattern.
Purity by HPLC
The share of the sample that is the target compound, reported as a percentage. Threshold for release: >99% for synthetic peptides.
Residual solvent
Traces of the solvents used during synthesis (acetonitrile, methanol, TFA). Reported in ppm against ICH Q3C limits.
Microbial & endotoxin
Endotoxin (LAL) and bioburden panels run on every batch. Limits aligned with parenteral-grade research material.
