Research-grade GHK-Cu should have batch-specific Certificates of Analysis showing third-party HPLC purity testing and mass spectrometry molecular identity confirmation
Always audit your formulary and check your states rules before prescribing anything new
General and applied toxicology
It is the predominant intracellular non-protein thiol in mammalian tissues, present at concentrations typically ranging from 110 mM in the cytosol, with particularly high concentrations in the liver (up to 10 mM), which is the primary site of GSH synthesis and export
Low molecular Copper Tripeptide-1 (GHK-Cu) with 99% purity 1,000ppm helps reduce the appearance of fine lines and sagging by promoting collagen and elastin production deep within the skin, delivering visible skin regeneration and long-lasting firmness
That's a real basis for interest, not proof of a rosacea-specific outcome
