A 5 to 8 minute plasma half-life means that by the time subcutaneously injected DSIP is absorbed from the injection site, cleared through lymphatics into venous blood, and circulated, a very substantial fraction has already been enzymatically degraded
Laboratory studies have also reported changes in growth hormone receptor expression in tendon fibroblasts exposed to BPC-157, suggesting a role in connective-tissue signaling environments [5]
Because the peptide occurs naturally in human plasma (at roughly 200 ng/mL in young adults, declining to approximately 80 ng/mL by age 60), topical supplementation essentially restores youthful local concentrations in treated skin
