Nobody is talking about the one with 50 years of published research that your body is already making and losing as you age. GHK-Cu is a naturally occurring tripeptide that declines by 60% between the ages of 20 and 60. That decline tracks directly with the loss of skin elasticity, slower wound healing, thinning hair, reduced collagen production, and rising inflammation. In randomized controlled trials it has outperformed Rogaine for hair growth, shown a 55% reduction in visible wrinkles, and been documented to positively affect the expression of over 4,000 human genes. Dr. G calls it his favorite peptide, and his partner uses it on her face every day. In this episode, you will learn: • How GHK-Cu works as a copper delivery vehicle at the cellular level, why it modulates gene expression across 31% of the human genome, and what that means for tissue repair, inflammation, and biological aging • The head to head randomized controlled trial where GHK-Cu outperformed minoxidil for hair count…
