When more than one lab tests the same batch, we line up their results side by side. When they match, it is the strongest signal you can get. When they do not, that is information too. Here is what these labs found — you decide.
2 independent labs tested this batch of Retatrutide from The Research Protocol. Their purity results ranged from 99.8% to 99.8%.
The labs agree
Independent labs landed within 2 points of each other on purity. That is the strongest signal you can get on a batch.

The two badges above are our blended RV-score view: whether the scores agree, and the overall quality tier. The plain read at the top leads with the labs actual purity numbers, and the full per-lab table is below.
Retatrutide from The Research Protocol
vendor batch label "RT10 2605-08" · cross-tested by 2 independent labs
Labs differ by more than 3 RV-score points. Worth digging in — could be method gaps, batch heterogeneity, or one outlier test.
ⓘ Batch identity basis: Vendor-claimed batch: 'RT10 2605-08'
Grouped by the vendor's batch label. We don't independently verify lot identity — if multiple physical lots were sold under this label, they'd be lumped together here. Use the agreement signal with appropriate caution.
Disagreement, but method data is sparse. Disagreement detected but method data is missing on too many records to attribute the cause. Once more records in this group carry resolved method info, this verdict will sharpen.

Per-Lab Breakdown

|---|---|---|---|---|---|---|---|---|---|---|

Why this matters: A single COA is one lab's answer from one method on one sample. Multiple labs reveal the pattern. When labs converge on the same answer, that's strong cross-validation. When they diverge — especially on content while agreeing on purity — the difference is often method-driven (different quantitation basis) but sometimes signals real product variation. ResearchVerify is the only platform that surfaces both cases automatically across thousands of cross-tests.
