ResearchVerify

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.

4 independent labs tested this batch of Semaglutide from Nuscience Peptides. Their purity results ranged from 95.9% to 99.9%.
Close, with minor variation

The labs are within a few points of each other, which is normal method-to-method variation.

On the actual amount per vial, the labs were nearly identical (5.0 to 5.4 mg).

⚠ One lab came back sharply different from the rest (flagged and highlighted in the table below). It counts toward the range above but is pulled out of the agreement math.

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.

Semaglutide from Nuscience Peptides
batch 00256 · cross-tested by 4 independent labs

Independent labs agree on this batch within 0.5 RV-score points. Strong cross-validation.

✓ Batch identity basis: Same physical sample (Finnrick multi-lab program)
All records carry Finnrick (FNR-*) task IDs, meaning one physical vial was routed by Finnrick to multiple labs and each lab tested it independently. This is the strongest basis for 'same batch' — there's no batch heterogeneity between labs because there's no batch difference: it's the same vial.

Outlier detected. One or more records in this group are statistically unusual (|z-score| > 2.0) compared to the others. Highlighted rows above show the flagged tests. Common causes: differing test methods, lab calibration drift, sample handling, or a genuinely heterogeneous batch.
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.
