Oral Capsule Bioavailability Oral administration represents the most familiar and convenient delivery method, but faces unique challenges with peptide compounds: Absorption Rate : 30-50% typical bioavailability [3] Key Challenges : Peptides must survive stomach acid (pH 1.5-3.5) Digestive enzymes (pepsin, trypsin) break down protein structures First-pass metabolism in liver reduces available compound Absorption occurs primarily in small intestine Despite these obstacles, BPC-157's inherent stability in gastric acid gives it an advantage over many other peptides

Anti-tumor immune cells, such as T cells, can induce tumor cells to undergo pyroptosis while simultaneously increasing ROS to trigger ferroptosis, thereby exerting anti-tumor effects (198, 199)
