DSIP 5 mg

A certificate of analysis (COA) is the third-party report for a specific lot: what the material was tested for, which methods were used, and what the results were. Each lot number receives its own COA.

When a product shows "COA pending," the batch is in testing or the certificate is still being filed. We do not publish a figure without the test report to back it up. Once the lot clears testing, the certificate is published and filed by batch number.

Because these are laboratory materials whose chain of custody cannot be verified once they leave us, we do not accept returns on opened or used vials.

For unopened, unused material in original packaging, returns may be considered on a case-by-case basis. See our full returns policy.
