This discussion compares tripeptides, exemplified by the well-studied GHK, with larger peptides such as the cyclic heptapeptide CyRL-QN15, the human cathelicidin-derived antimicrobial peptide LL-37, and the peptide Andersonin W-1 (AW1), containing 7, 37, and 72 amino acids, respectively [25, 67, 68]
The first was discovered in the early 2000s
With regards to the claims made that the treatment is virtually painless, we struggle to ever support that anything injected into the body is pain free, yes discomfort can be minimised when performing aesthetic procedures but we struggle to see how a procedure that takes needle to skin and has the mechanism of eliminating tissue from the body can be virtually devoid of pain
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a tripeptide that naturally binds copper ions and circulates in blood, saliva, and urine
For one thing, drinking alcohol can lead to dehydration, as well as electrolyte imbalances
