A study in the Journal of Neurology, Neurosurgery, and Psychiatry found it helped patients with diabetic neuropathy
It preserves the integrity of your expensive peptide for the duration of its use
In research settings it is typically reconstituted to 510 mg/ml again, a much higher concentration than semaglutide
Analytical Identity Copper Tripeptide-1 (GHK-Cu, CAS 89030-95-5) is a naturally occurring copper-binding tripeptide - glycyl-L-histidyl-L-lysine chelated to a divalent copper ion (Cu2+) - first identified in human plasma, where its concentration has been reported to decline with age, and later characterized in saliva and other biological fluids
[12] To be scrupulously fair: GHK-Cu is a chelated copper complex, and chelation is precisely the argument its proponents make that bound copper is not free copper, that the tripeptide delivers copper into physiological handling pathways rather than dumping ionic copper into tissue
