🧪 Is GHK-Cu Overrated? The Science of Copper Peptides Explained
Are Copper Peptides (GHK-Cu) actual anti-aging powerhouses, or just smart marketing hype?
In this video, we dive deep into the 50-year scientific history of GHK-Cu, breaking down the exact biological pathways behind collagen and elastin synthesis. We analyze the physiological realities of peptide size, molecular weight, and the famous 500 Dalton Rule to reveal how much of your product actually penetrates the skin barrier. And most importantly... all the theories and in vitro studies aside, what do the clinical studies REALLY say?
