TB-500 is discussed as a repair peptide connected with thymosin beta-4, a naturally occurring protein involved in actin, cell movement and wound-healing biology.

BPC-157

BPC-157 is the peptide that arrives online wearing a hard hat and carrying twelve before-and-after photos of tendons.

GHK-Cu

GHK-Cu is a naturally occurring three-amino-acid peptide that binds copper. Think of it as a tiny restoration specialist who refuses to work unless he has brought his own copper toolbox.

KPV

KPV is only three amino acids long – lysine, proline and valine – and comes from the tail end of alpha-MSH, a much larger signalling peptide.
