ghk cu hair growth microneedling study Copper Peptide Regrowth (2025) — Research Summary Microneedling for Hair Growth: GHK-CU

For doses of 10 units or less , a 30- or 50-unit insulin syringe improves readability

Currently we ship within the USA only

The dose is deliberately high compared to classical peptides (5-10 mg for GLP-1 analogues, 2-5 mg for short regeneratives) because documented GHK-Cu protocols use larger quantities in trichological and cutaneous research (1-3 mg per injection, concentrated topical applications)

Menkes disease MD is an X-linked recessive disease that affects Cu metabolism and is caused by mutations in the ATP7A gene

This 100mg lyophilized peptide complex exhibits strong copper affinity and plays a role in wound healing, tissue remodeling, and gene expression associated with repair processes
