- The GHK-Cu entry notes that human studies are often small and many are funded by the cosmetic industry.
Field notes
The entries connect named sequences to origins and research context: palmitoyl pentapeptide-4 is described as a procollagen-derived sequence with a 16-carbon palmitoyl chain, while GHK-Cu is identified as a copper complex isolated from human plasma in 1973. The page also cautions that the reported cosmetic effects have limits, including modest results for palmitoyl pentapeptide-4 and uncertain delivery of acetyl hexapeptide-8 to deeper targets.
