Calprotectin is a protein released by neutrophils (immune cells) in the gut lining when there's active inflammation

An interesting experiment shows how, in the presence of insulin resistance, there is up-regulation of the insulin/IGF-1 hybrid receptor expression in both, muscle and fat [133, 156]

Studies in rats for injury have looked at 10ng/kg up to 10mcg/kg both orally and via injection.6 The human equivalent dose of 10mcg/kg in rats per FDA provided calculations would be 1.89mcg/kg, corresponding to approximately 110 130mcg doses in a 60 to 70kg human.7 Though appropriate dosing for humans remains unclear given the lack of studies, animal data suggests a very favorable safety profile, with studies unable to report the acute lethal or toxic dose via the intramuscular, intraperitoneal, intravenous, or oral routes in animal trials in rats or dogs looking at dosing from 6mcg/kg all the way up to 20mg/kg over a 6 week period.5 BPC-157 has also been studied in a limited capacity topically in animals, with one study on burn wounds evaluating the effect of BPC-157 in a cream at 1mcg/g
