Our testing
Six tests. Every lot. No exceptions.
Before any batch reaches the catalogue, multiple vials are pulled at random and sent to an independent analytical laboratory. If a single result misses specification, the lot is rejected.

What every Certificate of Analysis includes
Identity
Confirms the molecular mass matches the reference compound, so you get exactly the peptide on the label.
Purity
Separates and quantifies the target peptide against related impurities. Our release threshold is 99.0%.
Quantity
Measures net peptide content per vial against the label claim, so a 10mg vial really holds 10mg.
Endotoxin
Screens for bacterial endotoxins that could confound cell-based assays.
Heavy metals
Checks for lead, arsenic, cadmium and mercury residues from synthesis.
Appearance
Confirms a uniform lyophilized cake with no discoloration or moisture.
Chain of custody
Traceable by batch number
The batch number printed on every vial matches one report. Look it up any time, attach it to your lab notebook, and know that every vial in a kit shares the same lot.
