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.

3 independent labs tested this batch of Ipamorelin from PurePeptides. Their purity results ranged from 71.1% to 80%.
Mixed results

The labs came back several points apart. Worth understanding why before leaning on any single number.

On the actual amount per vial, the labs were close (1.2 to 1.4 mg).

Heads up: our overall RV score may read these labs as close. That is because the score blends purity with other factors and compresses big differences. When you weigh this batch, the raw purity range above is what matters, not the smoothed score.

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.

Ipamorelin from PurePeptides
batch 2024-01-05 · cross-tested by 3 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.

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.
