Quality & Certificates of Analysis
We prove quality with documents, not adjectives — independent third-party testing and a COA for every batch.
Independent third-party testing on every batch
Each production batch is tested by an independent third-party laboratory using HPLC (for purity) and mass spectrometry (for identity). The resulting Certificate of Analysis reports the batch number, purity percentage, and method — so you can confirm quality yourself, not take our word for it.
- HPLC purity — the target compound as a share of total, with chromatogram.
- Mass-spec identity — molecular weight confirms the correct peptide.
- Batch traceability — the COA's batch number matches the vial.

Frequently asked questions
Does every batch come with a Certificate of Analysis?
Yes. Every production batch is third-party tested and issued a Certificate of Analysis (COA) reporting HPLC purity and identity, tied to a traceable batch number. We share the matching batch COA on inquiry.
What testing methods do you use?
Identity and purity are verified by HPLC (High-Performance Liquid Chromatography) and mass spectrometry, performed by an independent third-party laboratory.
Can I verify a COA independently?
Yes. Each COA names the testing lab, batch number, method, and date, so the result can be cross-checked. The batch number on the COA matches the vial.
What purity do your peptides report?
Research peptides typically report 98–99%+ HPLC purity, documented per batch on the COA. Exact figures are stated on each batch document.
