copper peptide ghk-cu acne “Is actually worth it?” is genuinely one of the most common questions in my comments, so let me finally answer it properly., The short version: peptides have real research behind them, An Essential Guide to GHK-Cu

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

If you need to store reconstituted GHK-Cu for longer periods, aliquot into single-use volumes before freezing
