The isolated fraction induced delta-wave (slow-wave) sleep when injected into recipient animals giving the peptide its name and initiated one of the most distinctive research trajectories in neuropeptide biology: a compound with a clearly demonstrated biological name-property, an exceptionally wide pharmacological activity profile, and nearly five decades later a receptor that remains formally uncharacterised
This explains why so many peptide therapy protocols recommend evening application
GHK-Cu, in contrast, delivers copper(II) ions to metalloenzymes such as lysyl oxidase (critical for collagen and elastin cross-linking), superoxide dismutase (antioxidant defense), and cytochrome c oxidase (mitochondrial respiration)

It should be noted that while both peptides have been individually studied extensively, published research specifically examining the combination of BPC-157 and TB-500 together is limited
