{"id":"bpc-157","name":"BPC-157","aliases":["Body Protection Compound 157","BPC157","Bepecin"],"url":"https://lyoresearch.com/compounds/bpc-157","summary":"BPC-157 is a synthetic 15-amino-acid peptide derived from a protein found in human gastric juice. In rodents it consistently speeds healing of tendon, ligament, muscle and gut injury. In people it has never been tested in a controlled trial, so every human claim about it — healing, pain relief, safety — is currently unproven. It is not an approved medicine anywhere and is prohibited in sport.","overall_grade":"D","overall_grade_meaning":"no human evidence","human_trials":"0 controlled","regulatory_status":"Not approved","outcomes":[{"outcome":"Tendon & ligament healing","grade":"D","grade_meaning":"no human evidence","effect_size":"not measurable","adverse":false,"human_studies":"0 controlled","evidence":"Rodent models of Achilles and MCL injury.
