topical ghk-cu Serum: Benefits, Mechanism & Research Guide GHK-Cu Topical vs Injection |

BPC-157 is a peptide being studied for repair, recovery, gut health, and tissue support

Research has demonstrated that GHK-Cu treatment increases production of collagen (particularly type I and type III collagen, the predominant structural collagens in skin and connective tissues), glycosaminoglycans (including hyaluronic acid, which provides hydration, volume, and biochemical signaling in skin), decorin (a small proteoglycan involved in collagen fibril organization and growth factor regulation), and other matrix molecules critical for tissue structure and function

Zepbound's higher efficacy has allowed it to win significant market share, and Lilly is planning to launch a next-generation obesity drug that targets three gut hormones and has promoted more than 28% weight loss in clinical trials
