What is a COA (Certificate of Analysis)?

Tested. Verified. Documented.

A Certificate of Analysis (“COA”) is documentation issued by an independent third-party laboratory verifying the analytical characteristics and molecular identity of a product through multiple validated testing parameters.

Each production batch undergoes rigorous third-party testing through an ISO/IEC 17025 accredited laboratory, and at Peptico, our analytical testing panels are designed to exceed typical industry benchmarks.

Batch-specific documentation is maintained to support purity assessment, identity verification, and transparent analytical reporting.

Analytical Testing Methods​

Each production batch is evaluated using established laboratory procedures designed to support identity verification, purity assessment, and overall batch consistency.

ISO/IEC 17025 Accredited Laboratory

Testing performed through an internationally accredited laboratory operating under globally recognized quality standards.

LC-MS Identity Verification

LC-MS identity testing performed to verify the material matches the expected reference compound and analytical profile.

HPLC Purity Verification

Quantitative purity analysis performed to verify purity levels ≥99%.

Batch Conformity Testing

Additional analytical testing performed to evaluate consistency between samples from the same production lot.

Endotoxin Tested (USP <85>)

LAL testing performed to verify endotoxin levels within established analytical limits and quality specifications.

PCR Sterility Screening

PCR screening performed to verify product sterility.

atom-solid

ICP-MS Heavy Metals Testing

ICP-MS analysis performed to detect trace elemental and heavy metal contamination at low concentrations.

Full COA Documentation

Complete batch-specific analytical documentation available through the COA Vault for independent review and verification.

Frequently Asked Questions

What is a Certificate of Analysis (COA)?
A Certificate of Analysis (“COA”) is documentation issued by an independent third-party laboratory verifying the analytical characteristics and molecular identity of a product through multiple validated testing parameters. All of Peptico’s COA’s come from an ISO/IEC 17025 Accredited Laboratory.
Third-party testing means analytical review is performed independently rather than relying solely on internal supplier documentation.
Production batches undergo batch-specific analytical review prior to release as part of internal quality control and documentation procedures.
Batch traceability helps connect a specific vial to corresponding analytical documentation and laboratory reporting records.
