Results showed that GHK-Cu upregulated SIRT1 protein expression and suppressed the expression of phosphorylated p-STAT3 in colon tissue and MCECs of the co-culture model
They've earned a serious reputation in dermatology and trichology and for good reason
Some investigators have examined both peptides concurrently in tissue repair models, noting that their non-overlapping pathways may produce complementary downstream effects on vascularization and extracellular matrix remodeling
For receptor-defined peptides, researchers can often verify activity through receptor binding or pathway-specific activation
