The organization of the experiments complied with the ethical standards governing experiments on animals (European Convention for the Protection of Vertebrate Animals used for Experimental or other Scientific Purposes: EST No
The AUC obtained from the zero time experiment was considered to represent the "100%" drug concentration and was used to determine the decreased drag concentration at each specified time interval

Commonly Reported Research Observations Injection-site redness or irritation Temporary swelling or warmth sensation at the administration site Burning or stinging during administration Temporary skin sensitivity or irritation Mild headaches Temporary fatigue or tiredness Mild nausea Temporary itching or flushing sensations Temporary blue-tinted discoloration beneath the administration area in some research settings Copper-Related Research Considerations Because GHK-Cu is a copper-binding peptide, some research protocols may monitor for: Copper- and zinc-balance variability Increased sensitivity in higher-frequency protocols Temporary skin-related response variability Individual differences in antioxidant-response pathways Research involving prolonged or higher-frequency protocols commonly investigates the inclusion of: Zinc supplementation Vitamin C supplementation alongside GHK-Curelated research models
