Also what defines these as a drug as opposed to a supplement?

Published mechanistic work points to BPC-157 enhancing VEGFR2 expression and downstream signalling activity in endothelial cells, rather than acting as a direct VEGFR2 ligand

It is incorporated into experiments examining synaptic communication, cellular differentiation, and receptor-mediated signaling

Signal Peptide Activity and Fibroblast Stimulation In-vitro studies on cultured dermal fibroblasts have consistently reported that GHK-Cu exposure at nanomolar to low-micromolar concentrations restores proliferative capacity in senescent or irradiated cells [2][3]

[1] It is most commonly evaluated in combination with CJC-1295, as the two compounds target complementary receptor pathways to support natural growth hormone production while preserving physiological pulsatility
