BPC-157 is a synthetic pentadecapeptide (a 15-amino-acid sequence) widely used as a reference compound in laboratory peptide research. It is one of the most frequently studied research peptides and appears often alongside TB-500 in comparative literature.
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.
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.
