BPC-157 (20mg) lot BPC20N100925 test results, explained
Every result printed on this certificate, as reported by Janoshik, with a plain-English note on what the test measures. "Pass" and "specification" wording comes from the certificate; where the lab prints no pass/fail, we say so.
| Test | Result on the certificate | What it measures | This lot |
|---|---|---|---|
| HPLC purity | 99.591% · Per vial: 99.765%; 99.818%; 99.591% (lowest, 99.591%, shown) | HPLC separates the sample into its components; purity is the share of the detected signal that sits in the main peak. On its own it doesn't show which molecule that peak is. That's what the identity test is for. | No pass/fail printed; reported value at or above 98% |
| Identity | Not reported | This certificate doesn't report an identity test, so it doesn't confirm which molecule is in the vial. Purity and quantity alone can't tell you that. | Not tested on this certificate |

About Janoshik
An independent analytical lab based in Prague, Czech Republic (Janoshik s.r.o.). Each report carries a task number and a unique verification key.
Accreditation: No accreditation is printed on these reports, and we found no published ISO/IEC 17025 accreditation for the lab (checked Oct 7, 2026).
Tests: On the reports here: HPLC purity and the measured content per vial. Other tests appear only when they're listed under Results.
How to verify: Go to janoshik.com/verify and enter the unique key printed on the report (the report's QR code links there too). Janoshik blocks automated checks, so we haven't matched these records ourselves.
