Your body makes this one — and makes less of it with time. Three amino acids on a single copper ion; the blue tint the solution takes on IS the copper binding.
Sold everywhere in language no journal would sign. The compound is real. The marketing isn't. Buy the one with a COA, not a promise.
Straight talk
Straight talk: the hype outruns the human data. The bulk of the published record is in vitro and animal-model work — decades of it, but a long paper trail is not a settled story. Human clinical evidence remains thin.
What the research studies
The literature, not a summary of it.
The serious work sits with Loren Pickart's group in Bellevue and François-Xavier Maquart's group at Reims. The literature spans wound-repair, dermatological, and matrix-biology journals — J Biol Chem, FEBS Letters, Biogerontology, IJMS. Read the research yourself:
