These include vitamin E, pioglitazone (PPAR agonist), obeticholic acid (farensoid X receptor agonist), cenicriviroc (CCR2/CCR5 antagonist), selonsertib (apoptosis signal-regulating kinase 1 inhibitor), and liraglutide (glucagon-like peptide 1 analogue) [136,137,138,139,140,141]
BENEFITS OF GHK-Cu GHK-Cu re-energizes skin cells and promotes skin-cell healthspan, providing a non-invasive system to combat fine lines and wrinkles without the need for invasive procedures
Mechanism Comparison Shared Pathway Both peptides activate GHSR-1a on pituitary somatotrophs, triggering: GHSR-1a Gq/11 PLC IP + DAG intracellular Ca release PKC activation Ca influx GH vesicle exocytosis This is fundamentally different from how GHRH analogs (CJC-1295, Sermorelin) work (GHRHR Gs cAMP PKA), which is why combining either GHRP with a GHRH analog produces synergistic GH release (Veldhuis et al., 2009)
