GHK-Cu is a naturally occurring copper-binding tripeptide complex (glycyl-L-histidyl-L-lysine bound to copper(II)) studied in laboratory research into matrix remodelling and copper-transport signalling. Its well-defined structure makes it a common reference compound in copper-peptide research.
TB-500 is a synthetic fragment peptide related to thymosin β4, used in laboratory research into actin-binding and cell-migration signalling. Its fragment structure makes it a common comparator to full-length peptides in research settings.
Both compounds are supplied strictly for in-vitro laboratory research use only. Not for human or veterinary use. This comparison is structural and contextual and does not constitute advice on use.
