Quality Documentation

A batch-specific Certificate of Analysis and applicable analytical documentation should be available for each lot. Verify peptide identity, exact sequence, amino acid substitutions, absence of the DAC moiety, C-terminal amidation, purity, molecular weight, formulation details, counterion content, and batch information against the records supplied with the individual product.

The molecular formula and molecular weight listed above correspond to the free CJC-1295 (no DAC) / Modified GRF (1-29) peptide. Acetate or other counterion-containing preparations may have different overall compositions. CJC-1295 with DAC is also a structurally distinct material and should not be represented using the no-DAC specifications.

Because CJC-1295 nomenclature and CAS assignments have historically been inconsistent across commercial databases, batch-specific sequence confirmation, HPLC, and mass-spectrometric documentation should be treated as the final reference for product identity.
