Medication was administered as described previously[21 (link)-25 (link)], without use of a carrier or peptidase inhibitor, for stable gastric pentadecapeptide BPC 157, a partial sequence of the human gastric juice protein BPC, which was freely soluble in water at pH 7.0 and in saline. BPC 157 (GEPPPGKPADDAGLV, molecular weight 1419; Diagen, Slovenia) was prepared as a peptide with 99% high-performance liquid chromatography purity, with 1-des-Gly peptide being the main impurity. The dose and application regimens were as described previously[8 (link)-20 (link)].
