Our verification process
Every batch follows a five-step verification chain — from synthesis to published Certificate of Analysis.
Solid-Phase Synthesis
Peptides manufactured by SPPS with precise amino acid coupling and sequence control.
HPLC Purification
Crude peptide purified to 99%+ by reverse-phase chromatography, removing truncated sequences.
Independent HPLC Testing
Every batch independently tested at our UK laboratory for purity quantification.
Mass Spectrometry
Molecular identity confirmed by MS, verifying the compound matches its expected weight.
Published COA
Certificate of Analysis published for every batch on our lab results page — verify before you buy.
