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 Retatrutide from Injectify. Their purity results ranged from 97.3% to 99.8%.
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 (9.7 to 10.9 mg).

Retatrutide from Injectify
batch PE2401-630 · 3 independent measurements across 3 labs (after collapsing same-test duplicates)
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.
⚠ Same-test duplicates detected (2 records in 1 cluster).
Some rows share identical measurement tuples (content + purity + date) — these appear to be one test counted multiple times, not independent measurements. They're flagged "SAME TEST" in the table below and collapsed to one vote for the cross-lab agreement math. Cross-lab corroboration requires actually-independent tests.

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.
