Topical GHK-Cu produces negligible systemic absorption transdermal bioavailability is less than 5% for unformulated aqueous solutions and rarely exceeds 1015% even with penetration enhancers like liposomes or DMSO
GUARANTEED DELIVERY OR FULL REFUND Recovery and repair peptide products related to tissue-support pathways, soft-tissue response, cellular repair models, connective tissue support, and regeneration-related mechanisms
The mechanism of action isnt well understood, but its believed it doesnt affect the tendon tissue cells directly, but rather that either works by activating other repair cells that can help tendons or ligaments or making the human growth factor receptor on the repair cells more sensitive (3)
