About this trial
This study will evaluate whether a topical gel containing GHK-Cu (a copper(II)-peptide complex) can safely speed up healing of small, standardized skin wounds in healthy adults compared with a matching vehicle gel.
Participants will receive two small punch-biopsy wounds on the upper arm; each wound will be randomly assigned to receive GHK-Cu gel or vehicle gel under identical dressings. Wounds will be photographed and assessed over 3 weeks, with a follow-up visit to evaluate scar quality.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Age 18 to 55 years at screening.
Healthy adult as determined by medical history and limited physical examination.
Body mass index (BMI) 18.0 to 30.0 kg/m².
Willing and able to comply with study visits and daily product application for 14 days.
Disqualifiers
Known allergy or sensitivity to copper, peptides, gel excipients, adhesives, or dressings used in the study.

Assessed by digital planimetry from standardized photographs.
Proportion of wounds healed
Binary outcomes derived from re-epithelialization assessment.
Incidence of suspected or confirmed wound infection
Assessed clinically; swab/culture if clinically indicated
Participant-reported wound pain
0-10 numeric rating scale recorded daily
