BPC-157 TB-500 references identify the source for each claim

Where did a claim come from? Its number leads to a paper or published FDA notice listed below. Those sources don’t supply missing evidence for your treatment.

The number after a claim points to its source below

Where can you check the basis of a BPC-157 TB-500 claim? Match the number beside the claim with the numbered source below. Entries 1-8 concern published research; entries 9-10 concern FDA's pharmacy ingredient rules. The links open papers or their published details. The research examines BPC-157 or Thymosin Beta-4 / TB-500 separately, rather than a trial comparing people given the mixture with untreated people. Those separate findings cannot establish a benefit from receiving both. The treatment answers explain what the gap means for your care.

The substance actually tested matters more than the name used in a claim.
