A peptide blend is more than two vials in one — the COA changes shape entirely. Here is how research labs evaluate blended reference material.
A peptide blend is a co-lyophilised mixture of two or more peptides in a single vial at defined masses. Blends exist for convenience — a single reconstitution reduces analytical variability across concurrent assays.
What a blend COA must show
- Individual HPLC purity per peptide.
- Individual quantified peptide content per vial (mg per component).
- Counterion identity and content per peptide.
- Confirmation that the two peptides do not co-elute — otherwise purity cannot be validated.
Common blend patterns
- GH secretagogue: CJC-1295 + Ipamorelin.
- Tissue-research: BPC-157 + TB-500 (the 'Wolverine' pattern).
- Metabolic combination: cagrilintide + semaglutide (CagriSema pattern).
