WHAT THE CERTIFICATE REPORTS

7 of 7 evidence categories documented.

The supplier product page, signed ILS certificate, and laboratory verification record align on the lot, access code, purity, total content, and reported test panel. Reference: COA-2026-RNX8QR · LOT 128-01-SM.

Contaminants

Not DetectedArsenic, cadmium, chromium, mercury, lead + fentanyl screen
MEASURED TOTAL CONTENT20.99 mg

The reported net blend content is about 4.95% above the 20 mg label. The certificate lists the total as report-only and does not assign a content pass/fail specification.

WHAT THE HEADLINE DOES NOT SAY

Four limits that belong beside the score.

01

Identity is HPLC-based, not mass spectrometry

The lab confirms both named components by chromatographic retention-time comparison with reference standards. The report does not show LC-MS or high-resolution mass confirmation.

02

Component amounts are calculated

The 10.70 mg BPC-157 and 10.29 mg TB-500/TB-4 entries are calculated from measured total blend content using the manufacturer’s stated formulation ratio. They are not presented as independent component-content assays.

03

PCR is a rapid microbial screen

The “No Growth” result comes from PCR-based sterility testing. The certificate does not describe a traditional compendial USP <71> sterility study, so the exact method boundary should remain visible.

04

Seven categories still do not mean every possible test

The contaminant panel covers five metals and fentanyl, while the purity method excludes non-peptide process-related impurities from the percentage. Residual solvents and other unlisted analytes are not established by this report.

COMPOUND IQ VERDICT

Strong, current, lot-matched documentation—with clearly defined method limits.

This certificate earns full document-coverage marks because it reports identity, purity, measured total content, lot traceability, a PCR microbial screen, quantitative endotoxin, heavy metals, and a fentanyl screen. The product page also matches the certificate’s lot and access code. That makes this a strong public-document example, even though component quantities are calculated, identity is HPLC-based, and the result still applies only to the submitted sample.
