GHK-Cu (CAS 89030-95-5), also known as Copper Tripeptide-1, is a naturally occurring copper-chelating tripeptide complex with the molecular formula C14H24CuN6O4 and a molecular weight of 403.91 g/mol
In the lab, researchers use it to see how cells respond to copper and small peptides
Oral NAD+ does not survive digestion intact
Groups at higher risk of deficiency include older adults (due to reduced stomach acid production), people following vegan or strict vegetarian diets (as B12 is naturally found almost exclusively in animal products), individuals with pernicious anaemia or other malabsorption conditions, those taking certain medications such as metformin or proton pump inhibitors long-term, and people with significant nitrous oxide exposure (including recreational use), which can inactivate B12 in the body
A clinical trial that involved GHK-Cu in addition to standard wound care also reported an apparently reduced risk of infection compared to standard processes alone
