Participants would be randomized to injectable GHK-Cu, to placebo injection, and ideally to a topical GHK-Cu arm for a route comparison
Key characteristics: A short fragment (approximately 1517 amino acids depending on the exact modification) rather than a full-length hormone Referenced in literature exploring structure-activity relationships within specific growth hormone fragments Distinct in origin and mechanism of interest from full-length growth hormone or GHRH analogues such as tesamorelin Structural Comparison Table Why Researchers Distinguish Between Them Despite both being short peptides sometimes discussed in metabolic research contexts, MOTS-C and AOD9604 have entirely different biological origins and mechanisms of research interest
