- The notation confusion isn't trivial. Researchers contacting suppliers, reviewing study protocols, or cross-referencing published literature routinely encounter both 'AOD-9604' and 'AOD9604' and reasonably wonder whether the hyphen signals a structural difference, purity grade variation, or distinct peptide altogether. Here's what matters: the hyphen is a formatting convention only. Both terms refer to the identical 15-amino-acid C-terminal fragment (residues 177–191) of human growth hormone. The peptide's amino acid sequence, molecular weight (1815.08 Da), and mechanism remain unchanged regardless of how the identifier is written.
- Our team sources peptides across dozens of suppliers annually. The naming inconsistency appears most frequently when comparing European regulatory filings (which favour 'AOD-9604') with supplier catalogues and research protocols published outside standardised nomenclature systems (which often drop the hyphen). The peptide itself doesn't change. The identifier does.
- What's the difference between AOD-9604 and AOD9604?
- There is no chemical, structural, or functional difference between AOD-9604 and AOD9604. Both names refer to the same synthetic peptide fragment. A modified version of amino acids 177–191 from the C-terminus of human growth hormone. The hyphen is a typographic convention adopted by some manufacturers and researchers but absent in others. The sequence, purity specifications, and biological mechanism are identical.
