In one mouse study, researchers found that the peptide reduced the pain felt by the animals in their paws when placed on a mildly hot plate. The authors explained that this could be because GHK is similar in structure to cimetidine, a histamine H2 receptor antagonist sometimes given to reduce pain in certain digestive conditions.3 10 In rodents, doses as low as 0.5mg/kg were found to be effective in delivering these anti-pain effects.25 In a 70kg human, an equivalent dose would be around 5.6mg, though thats likely higher than necessary: pharmaceutical-grade GHK-Cu normally ranges from 0.5 mg to 2.5mg per injection

For hair growth specifically, combining topical GHK-Cu with microneedling is supported by the strongest evidence as shown in the 2025 Kuceki study which achieved 26.5% regrowth with this combination approach

It's important to note that GHK-Cu supports viable follicles but cannot revive completely dead or fibrosed ones

The peptide's biological activity in research models depends on its 1:1 chelation of a copper(II) ion
