Certificate of Analysis
Every peptide we sell is third-party tested and comes with full documentation of purity and identity verification.
Our Commitment
Transparency You Can Trust
A Certificate of Analysis is an official document from an accredited third-party laboratory that confirms the identity and purity of a compound. Every batch we ship is independently tested before it reaches your lab — no exceptions. We publish these results openly so you can verify what you ordered.
Analytical Methods
Our Testing Methods
HPLC Purity Analysis
High-Performance Liquid Chromatography separates and quantifies each compound to confirm purity. Results are expressed as area-under-curve percentage against the total chromatogram.
Mass Spectrometry (ESI-MS)
Electrospray Ionization Mass Spectrometry confirms molecular identity by matching observed mass-to-charge ratio against the theoretical molecular weight of the target peptide.
Identity Verification (AAA)
Amino Acid Analysis provides a quantitative breakdown of the amino acid composition, confirming that the peptide sequence matches the declared structure.
Batch Documentation
Every production run receives a unique batch number. Full COA documents — including raw data, instrument reports, and analyst signatures — are retained and available on request.
