Quick answer In circulating reference protocols a 20 mg blend vial (10 mg BPC-157 + 10 mg TB-500) is commonly reconstituted with 2 mL of bacteriostatic water yielding 5 mg/mL of each peptide and community conventions describe roughly 250500 mcg of each peptide subcutaneously per dose
It is used clinically and in research for tissue repair, with studies covering tendon and ligament injury, muscle strain, gut lining damage (including ulcers and inflammatory bowel conditions), and post-surgical recovery
Rigorous human pharmacokinetic data do not exist because no completed Phase 1-3 clinical trials have been published
It was previously available through compounding pharmacies as a bulk drug substance, but the FDA reclassified it as a Category 2 substance, which effectively restricts compounding pharmacies from producing it
