The purity assessment criteria for research-grade materials are generally much less rigorous, partially incomplete, and/or poorly followed, per a 2014 paper.21 Additionally, while some studies state that BPC-157 has good oral bioavailability based on its stability in human gastric juice, little if any research has investigated the differences in bioavailability between BPC-157 routes of administration.22 We could find only a single rat study that used oral BPC-157.23 So the best option would be an injectable form of BPC-157 from a reputable clinic
