Batch documentation, independently verified

Every batch is analyzed by an accredited third-party laboratory and documented on a batch-specific Certificate of Analysis.

See Methodology
A gloved hand holds a Cardinal Peptides vial above its printed Certificate of Analysis, beside an HPLC system.

HPLC purity verification

Each batch undergoes High-Performance Liquid Chromatography analysis, with results documented on the COA.

Independent laboratory

Analyses are performed by accredited third-party laboratories rather than in-house testing.

Batch-specific COAs

Documentation is batch-specific; mixed-lot reporting is never accepted.

Cold-chain packaging

Temperature-controlled packaging maintains lyophilized integrity from facility to laboratory.

Precision without compromise.

Cardinal Peptides supplies lyophilized, batch-verified reference materials to qualified research organizations. Documented at every step, and deliberately not a consumer brand.
