When designing research protocols for topical GHK-Cu, we recommend the following best practices: Application to Clean Skin: Ensure the skin is clean and dry before application to facilitate optimal absorption

During concurrent use , patients should contact their healthcare provider if they experience: Symptoms of hypoglycemia (shakiness, sweating, confusion, rapid heartbeat) Severe, persistent abdominal pain (often radiating to the back) with or without vomitingthis could indicate pancreatitis, a serious adverse effect associated with GLP-1 receptor agonists requiring urgent medical evaluation Unexplained fatigue, jaundice, or abdominal pain (potential liver concerns) Worsening gastrointestinal symptoms beyond typical semaglutide side effects New or unusual symptoms that may represent an adverse reaction Patients taking oral medications with a narrow therapeutic index should discuss timing and monitoring with their healthcare provider, as semaglutide's effect on gastric emptying may affect absorption
Semaglutide is a medication approved as a treatment for weight loss in obese or overweight adults
Monitoring progress is essential
