Peptide Intelligence
What is OTR-AC?
OTR-AC is the community name for oral high-dose BPC-157 acetate. The peptide sequence is identical to injectable BPC-157 (GEPPPGKPADDAGLV) but is dosed at 2-5 mg orally rather than 250-500 µg subcutaneously to compensate for GI degradation and first-pass metabolism.
How does OTR-AC dosing differ from injectable BPC-157?
Oral BPC-157 requires approximately 4-10x higher doses than subcutaneous injection due to partial degradation by stomach acid and intestinal enzymes. A common oral dose is 2-5 mg once daily compared to 250-500 µg once or twice daily for injection. Despite lower systemic bioavailability, the oral route provides direct mucosal contact throughout the GI tract.
Why stack OTR-AC with GLP-1 peptides like Tirzepatide?
GLP-1 receptor agonists commonly cause GI side effects including nausea, gastroparesis, and mucosal irritation. OTR-AC addresses these via BPC-157's gastroprotective and pro-kinetic mechanisms; it accelerates gastric emptying recovery and reduces GI inflammation via nitric oxide and growth factor pathways distinct from GLP-1 signaling.
