⏤ QUALITY & TESTING

A documentation-first approach to peptide supply.

Every lot we release is independently analyzed by accredited third-party laboratories. We commit to clear, batch-specific documentation so researchers can verify what they receive — without ambiguity.

UPLC purity

Ultra-performance liquid chromatography, area-percent purity. Validated analytical protocols followed for every sample.

Mass spectrometry identity

MS confirms the observed mass matches the expected molecular weight within method tolerance.

Sterility / endotoxin

USP <71> sterility and LAL endotoxin testing on selected lyophilized products.

⏤ DOCUMENTATION

Sample test report.

Each shipment includes a per-batch test report covering identity and purity by UPLC/MS, appearance, and (where applicable) sterility/endotoxin results. Every report is signed by the testing laboratory's research and formulation chemist and timestamped on the received and reported dates.

⏤ HOW WE WORK

Our analytical workflow.

Synthesis & receipt

Material is received from synthesis partners with pre-shipment documentation.

Independent sampling

A sample is drawn from each lot under controlled conditions.

Third-party analysis

Sample is sent to an independent, accredited laboratory for UPLC/MS analysis under validated protocols.

Documentation review

Results are reviewed against release specifications. Out-of-spec lots are quarantined.

Release & traceability

Released lots are barcoded, batch-numbered, and paired with a signed COA before warehousing.
