If the peptide is administered once in a way that creates a short signaling event, that protocol is functionally different from the same total amount divided across separate administrations
Chasing a substance no one was even sure existed
BPC-157, TB-500 and GHK-Cu are used in in-vitro systems, ex-vivo tissue explants and animal models to study endpoints such as endothelial-cell activity in angiogenesis assays, fibroblast-associated matrix gene expression, cell migration and wound closure
Namely, BPC 157 is always applied alone (i.e., its own effect ascribed only to the peptide (for review, see Sikiric et al., 1993
During a period of caloric deficit, when circulation may be a limiting factor for peripheral tissue repair, this matters
