If CNS penetration has not been quantified through CSF sampling or blood-brain barrier permeability assays, treat the peptide as potentially CNS-active and apply full neuropeptide interaction protocols staggered dosing, conservative peptide dose (5070% of standalone effective dose), and behavioral monitoring for serotonergic excess
Pentadecapeptide BPC 157 attenuates gastric lesions induced by alloxan in rats and mice
When those signals support restarting, protocols generally re-enter below the prior peak dose
Lets look at how we got here: BPC-157 is not new
Moreover, mounting evidence has demonstrated the feasibility of several types of CPPs, including TAT-PTD, TCTP-PTD, polyarginine, and penetratin and analogs thereof (Table 1), in the transepithelial delivery through nasal and intestinal epithelium (Zhu et al., 2014
