Every Bridge Labs certificate follows the same layout. This is a full example, clearly marked as a specimen, so you can see exactly what a report contains and learn to read one before you ever hold a real certificate.

This is a specimen. The figures are invented for layout only and the document is watermarked accordingly — it does not represent a real analysis. A genuine certificate carries real data and a working verification code.

How to read a report
A report is built to be read top to bottom: who and what was tested, then the measurements, then the proof it is genuine.
Header — what was tested
- Report number — a unique identifier for this analysis. It is what you cross-check against our verification page; no two reports share one.
- Dates — when testing was ordered, when the sample was received, and when the analysis was conducted. A relevant report is a recent one.
- Client — who submitted the sample. On a published copy this is kept confidential; the report still verifies.
- Sample & batch / lot — the compound and amount as labelled on the vial, and the batch it belongs to. Results apply to that batch, not to a brand in general.
- Sample description — the physical condition as received: form, fill, seal and any visible issues.
Results — the measurements
The results table has five columns: Test, Method, Result, Specification and Status. The specification is the acceptable range for that test; status is Pass when the result sits inside it.
- Purity (HPLC) — the proportion of the sample that is the target compound, as an area-percent of the chromatogram. High purity means few impurities relative to the main peak.
- Identity (LC-MS) — confirmation by mass that the molecule is the one named. The measured mass is compared with the value calculated from the stated sequence; a match supports the claimed identity.
- Peptide content — how many milligrams of peptide are actually present, read against the amount on the label. Purity is a proportion; content is the absolute quantity — both matter.
- Endotoxin (LAL) — bacterial endotoxin load in EU/mg, a separate safety parameter for material intended to be injected.
- Heavy metals (ICP-MS) — elemental impurity screening for arsenic, cadmium, lead and mercury, each against its own threshold. “Not detected” means below the method’s detection limit.
An overall verdict summarises the table: a pass means every analyte tested sat within its specification.
Footer — proof it is genuine
- Authorised signatory — the quality release for the analysis.
- Verification key & QR code — the code printed on the certificate. Enter it on our verify page or scan the QR; the matching report opens directly from us, never from a vendor.
- Integrity hash (SHA-256) — a fingerprint of the exact PDF. If a single byte of the document changes, the hash no longer matches, so an edited certificate is easy to spot.
- Scope & disclaimer — what the result does and does not cover.
The single most important check
A certificate is only as good as the code on it. Anyone can paste a logo onto a PDF; what they cannot do is make a forged code resolve on our site. Always finish by entering the code on the verify page — if it does not open a matching report there, the certificate did not come from us.
