About GHK-Cu copper peptide research
GHK-Cu is the tripeptide glycyl histidyl lysine complexed with copper, a compound studied in extracellular matrix, collagen synthesis and gene expression models in cell culture. As a preclinical research reagent it is supplied lyophilized for in vitro work. Read the GHK-Cu compound profile, the GHK-Cu copper peptide research overview and the GHK-Cu research update.
About melanocortin receptor research
Melanotan I is a linear alpha MSH analog studied mainly at the MC1R receptor, while Melanotan II is a cyclic analog with broader activity across MC1R, MC3R and MC4R. Both are used in receptor binding and signaling studies. For receptor level background, see the melanocortin receptor research overview and the MC4R research update. PT-141, a related melanocortin agonist, is listed in wellness research compounds.
About the KLOW blend
The KLOW blend combines GHK-Cu, KPV, BPC-157 and TB-500 in one vial for comparative multi peptide work. See how it fits into multi peptide research blends, view the KLOW blend product page and plan concentrations with the peptide reconstitution calculator.
