GHK-Cu and AHK-Cu are copper-binding peptides frequently studied in dermatological and tissue-regeneration research, both valued for their roles in copper delivery to cellular repair pathways.
GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-histidyl-lysine. It was first identified in human plasma and has since become a widely studied subject in skin research, with laboratory work examining its potential roles in collagen and elastin synthesis, antioxidant activity, and wound-healing models.
AHK-Cu is a related copper tripeptide complex, structurally similar to GHK-Cu but studied for its distinct affinity in hair follicle and dermal papilla research. Laboratory investigations have focused on its potential relevance to hair growth cycle modeling and follicle health studies.
Why Researchers Study Them Together
Because GHK-Cu and AHK-Cu are both copper-delivery peptides but show different tissue affinities, researchers often study them in parallel to compare their effects across skin, hair, and nail research models. This comparative approach helps clarify how subtle structural differences influence receptor binding and downstream cellular signaling.
Key Research Specifications
Purity: Research-grade GHK-Cu and AHK-Cu are typically supplied at greater than 98% purity, verified through HPLC testing.
Form: Both are commonly distributed as lyophilized powder for stability during storage and transport.
Storage: Vials should be kept frozen or refrigerated prior to reconstitution; once mixed, refrigerate and use within the recommended window.
Reconstitution: Bacteriostatic water or sterile water is the standard diluent used in research settings for both peptides.
