GHK-Cu occurs naturally in the body and plays a key role in signaling collagen production, wound healing, and cellular regeneration
It is classified as a triple incretin receptor agonist, meaning it simultaneously targets three hormone receptors: glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP), and glucagon receptors
This guide covers what GHK-Cu is, how it works, the benefits it offers for skin health when applied topically, and how it compares to other peptide therapies
The evidence questions the FDA raised do not disappear because a script exists
Recent studies also found that weight loss with HCG is mostly due to the strict diet, not the HCG itself
Peptides with very short half-lives, such as Sermorelin and Tesamorelin, produce sharp, pulsatile signals that mimic physiological release patterns, which is often desirable when studying hypothalamic feedback loops
