Tell me more about optimal dosage of BPC-157 peptide

The stated typical BPC-157 regimen is 300–500 micrograms subcutaneously two to three times per week, sometimes up to five days per week, for about eight weeks. This is a reported regimen, not an established human “optimal” dose: rigorous human evidence is lacking, and another physician in the discussion emphasized that the effective human dose remains unknown. 1 2 3

• Break between courses: A common pattern is to cycle off for eight to ten weeks after the roughly eight-week course. Continuous daily use without breaks was discouraged, with the caveat that human data and risks remain uncertain. 4
• Administration site: Injections may be systemic—such as subcutaneously a few inches from the belly button—or local, at or near an injury. Whether local administration works better is unsettled; reported experience did not clearly show that the route matters. 5 6
• Dose and risk caution: If used, the advice was to choose the minimum effective dose, avoid continuous daily use, and monitor health for possible tumor or cancer concerns. BPC-157 may increase angiogenesis, which raises concern about potentially supporting tumor growth. 7 8

Because the human dose and safety profile are not well established, the stated regimen should not be treated as a proven optimal dose. 9
