Its safety profile over decades of use makes it one of the most practitioner-trusted regenerative peptides in aesthetic medicine
Table 2 highlights distinct mechanisms and outcomes of peptides across wound healing models
They are cast as superior to growth hormone injections, which are accompanied by a laundry list of potential side effects including fluid retention and carpal tunnel syndrome, because you are not adding synthetic growth hormone to your body
For patients with Child-Pugh B or C liver disease who are interested in GHK-Cu for wound healing, skin rejuvenation, or hair follicle support, topical application represents the evidence-supported route
Copper Accumulation Concern The copper ion in GHK-Cu raises a theoretical concern about copper accumulation with prolonged high-dose use
So, its impossible to quantify the benefits of peptides as a group
