Topical Application: Apply directly to affected areas 1-2 times daily Concentration: 4% for most applications, may be increased for specific wound healing protocols Injectable Application: For systemic healing: 1-2 mg daily injection Duration: 4-6 weeks followed by assessment Studies report that GHK-Cu promotes cell proliferation and angiogenesis, potentially accelerating wound healing processes

This disruption severely compromises cellular capacity to reduce lipid hydroperoxides and synthesize glutathione, thereby dramatically increasing susceptibility to iron-dependent lipid peroxidation and ferroptotic cell death (148)

Peripheral opioid receptors, particularly upregulated during inflammation [59], offer a rationale for topical application in wounds, providing localized analgesia with a minimum systemic exposure

however, there were important limitations to consider, including small sample sizes, a lack of long-term observation, the use of a single species or strain, the lack of in-depth exploration of cellular or molecular mechanisms, failure to assess other aspects of reproductive function, a lack of validation of the clinical relevance, and a failure to consider individual differences in drug dosages
