GHK-Cu isn't new.
It's just been ignored.
Isolated in 1973 by Dr. Loren Pickart, GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring tripeptide that signals the skin to repair itself. Over fifty years of independent research documents its ability to stimulate collagen and elastin synthesis, reduce inflammation, accelerate wound closure, and upregulate antioxidant enzymes.
Most copper peptide products contain a trace amount — not enough to do anything meaningful. BLU° delivers GHK-Cu at 0.1%, the concentration used in peer-reviewed research. Not a proprietary blend with an undisclosed dose. The real number, stated plainly.
