ghk-cu leptin ghrelin JCI WHAT IS GHRELIN?

Serum leptin levels in male marathon athletes before and after the marathon run

Function: It specifically stimulates the release of GH without significantly affecting cortisol or prolactin levels

Patients in their 40s and 50s who have never addressed the GHK-Cu decline often present with compounded effects: skin that has thinned significantly, hair that has changed in texture and density over years, and a recovery timeline after procedures that is noticeably longer than it was in their 20s

Peptide therapy counteracts the natural decline in peptides that can occur with age, chronic stress, and certain medical conditions, such as diabetes, to improve biological function
