Enhanced healing of ulcers in patients with diabetes by topical treatment with glycyl-l-histidyl-l-lysine copper
Wound Repair and Regeneration, 1994 · Randomized placebo-controlled human study
Reported greater diabetic ulcer closure with a topical GHK-Cu gel plus standard wound care.
What this does not establish
Specific to one topical formulation and wound care; not evidence for other uses.
GHK-Cu questions
What is GHK-Cu?
GHK-Cu is the copper complex of glycyl-L-histidyl-L-lysine, a three-amino-acid peptide. The linked paper concerns a specific topical gel, not all copper-peptide products.
What does GHK-Cu do in the linked study?
The study reported improved ulcer closure with a topical GHK-Cu gel alongside standardized wound care. That finding belongs to the studied formulation and patient setting.
Does topical GHK-Cu research establish benefits for every use?
No. A diabetic-ulcer study cannot by itself support unrelated skin, hair, systemic, or other claims. Those would require their own relevant evidence.
Is GHK-Cu safe in every formulation?
The linked topical study does not establish safety for every formulation or route. A compound name and a purity percentage do not substitute for application-specific clinical evidence.
