FAQs What is copper peptide GHK-Cu used for in research
At a molecular weight of approximately 340 Da as the free tripeptide (see the GHK-Cu compound overview), it sits below the 500 Da threshold commonly associated with good dermal penetration a key reason GHK-Cu topical serum formulations achieve dermal absorption where many larger cosmetic peptides do not

Falutz J et al., 2010 [PubMed] Key Areas of Research: Molecular GHRH(144) receptor binding characterization, DPP-4 cleavage resistance via N-terminal trans-3-hexenoyl modification, somatotropic axis receptor interaction modeling, peptide structural stability assays Cellular / Endocrine Pituitary somatotroph signaling pathway characterization, IGF-1 axis modulation patterns, pulsatile GH secretion parameter assessment, GH pulse amplitude and frequency measurement in research models Systemic (Preclinical) Visceral adipose tissue compartment modeling, circulating lipid parameter profiling, hepatic steatosis research contexts, metabolic substrate monitoring in controlled investigational settings Together, these findings suggest broad experimental potential for Tesamorelin across hypothalamic-pituitary axis, adipose tissue compartment, and hepatic pathway research contexts
