If the eye area is sensitive, start by using it once daily, then gradually increase use according to skin tolerance

Dihexa was designed specifically to survive first-pass metabolism better than parent angiotensin IV analogs, but most vendor oral capsule claims are not supported by peer-reviewed pharmacokinetic data in humans

Research using the Broad Institute Connectivity Map analyzed 1,309 bioactive molecules and identified GHK-Cu as having remarkable gene expression modulation capabilities

Interestingly, introduction of carboxylic acid groups to RT slows down its reaction kinetics towards GSH comparing to RT-NH 2 and TQG-CN (Table 2), presumably due to the charge repulsion between the carboxylic acid groups and the anionic GSH
