Research Verify

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 KPV from Eros Peptides. Their purity results ranged from 99.3% to 99.4%.
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.

On the actual amount per vial, the labs were nearly identical (11.9 to 13.6 mg).

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.

KPV from Eros Peptides
vendor batch label "KPV29338A" · cross-tested by 2 independent labs

The blended RV scores land within 0.5 to 1.5 points of each other. The RV score mixes purity with other factors and can read as agreement even when raw purity does not — so weigh the raw purity range shown above.

ⓘ Batch identity basis: Vendor-claimed batch: 'KPV29338A'
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.
⇊ Canonical merge — Records using different spellings/names for the same compound were grouped under the canonical KPV. Source names: KPV, KPV10mg. Verified by the synonym resolver.
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.

These records lack parseable score, purity, and content fields. They're shown here for transparency but don't contribute to the cross-lab agreement statistics above.

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.
