The technique separates compounds based on hydrophobicity and molecular size, producing a chromatogram showing: Main peak purity : The percentage of total UV-absorbing material represented by the target peptide peak (should be 98% for research-grade material) Deletion sequences : Truncated peptides missing one or more amino acids, appearing as earlier-eluting peaks Insertion sequences : Longer-than-expected peptides from synthesis errors, appearing as later-eluting peaks Diastereomers : Peptides with incorrect amino acid stereochemistry, often appearing as shoulder peaks adjacent to the main peak Arma Peptides supplies BPC-157 5mg and BPC-157 10mg with batch-specific HPLC chromatograms showing 99% purity

It is not destroyed independent animal model work continues, and the HGF/c-Met mechanism has been corroborated by other labs but the specific dramatic synaptogenesis claims that made dihexa famous (the "7x BDNF" numbers) trace back to papers now under formal expressions of concern by the journals that published them

Key Takeaways NAD+ is not a peptide: it is a coenzyme called nicotinamide adenine dinucleotide, with no amino acids and no peptide bonds, so is NAD a peptide has a clear answer, no
