Match the material to the report
Ask whether the report covers the raw ingredient or the finished preparation. Ask how its batch code matches the proposed product.
A batch is a group prepared together. A report for a different batch does not answer your question about this one.
Purity leaves questions unanswered
Purity is a measure of how much of a sample is the intended substance.
In the BPC-157 review checked September 28, 2026, FDA found most certificates for the plain form reported purity without enough detail about impurities.
FDA is the US medicine regulator. Impurities are unwanted substances left in or formed during production.
A high purity result alone does not establish that a preparation is free of germs or poisons from bacteria.
An injection needs different checks
For an injected product, FDA's review identifies three key quality checks: tests for living germs, bacterial poisons and stray particles.
These are questions for the person responsible for the preparation. A reader cannot settle them by looking at a purity percentage.
Testing does not change approval
The September 28, 2026 record still contains no FDA-approved use for BPC-157.
Ask what the report leaves unknown about the ingredient, the finished preparation and the proposed treatment. A reply that only repeats the purity result leaves those questions open.
