The answer depends on dosage, consistency, absorption, and individual metabolism
BPC 157 stimulated both egr-1 and its co-repressor gene nab2 (Tkalcevic et al., 2007)
This characteristic sets it apart from many epitope tags that are simply short peptides
Illustratively, BPC 157 counteracted lidocaine convulsions [60], and thereby, likely also lidocaines effects on the central nervous system (i.e., inhibiting nicotinic acetylcholine receptors, inhibiting presynaptic calcium channels in the dorsal root ganglion, inhibiting opioid receptors, inhibiting of neurite growth, inhibiting muscarinic cholinergic receptors, and preventing substance P from binding to natural killer (NK) cell receptors) [278,281,282,283]
