Intelligence Profile
Safety Profile
The safety evidence for GHK-Cu (glycyl-L-histidyl-L-lysine-copper) is extremely limited in human studies. Available data comes primarily from animal research and limited clinical applications, making a comprehensive safety assessment difficult.
Known Side Effects
Evidence is thin regarding documented side effects in humans. The available research focuses mainly on:
- Animal studies in mice and C. elegans models showing behavioral and longevity effects
- Topical applications for wound healing and skin conditions
- In vitro studies examining biochemical properties
No systematic documentation of adverse events or comprehensive safety profiles were identified in the available evidence.
Contraindications
No specific contraindications are established based on the available evidence. However, given the copper component, theoretical concerns may include:
- Wilson's disease or other copper metabolism disorders
- Conditions requiring copper restriction
- Known allergies to copper or peptide compounds
These are theoretical considerations - specific contraindications have not been clinically established.
Drug Interactions
No drug interactions are documented in the available research. The evidence does not address potential interactions with medications or other compounds.
Populations That Should Exercise Caution
Due to insufficient human safety data, the following populations should be particularly cautious:
- Pregnant and breastfeeding women
- Children and adolescents
- Individuals with kidney or liver disease
- Patients with copper metabolism disorders
Current Clinical Investigation
One Phase 2 clinical trial (NCT07437586) is currently recruiting participants to study topical GHK-Cu gel for wound healing, which may provide more human safety data.
Important Limitations
The safety profile of GHK-Cu is poorly characterized in humans. Most available research involves animal models or in vitro studies. The lack of comprehensive human safety data, standardized dosing protocols, and long-term safety studies represents a significant evidence gap.
