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 SRY Labs. Their purity results ranged from 99.6% 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.
On the actual amount per vial, the labs were close (10.5 to 12.1 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.
Retatrutide from SRY Labs vendor batch label "F21750628" · 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: Same product — batch identity not established
Grouped by the vendor's batch label, but the records span 2 different labeled dose products. A batch label that covers multiple SKUs is a weak identifier — these are probably different physical lots, not one batch.
⚠ 1 record in this group failed QC.
Flagged "FAILED QC" in the table below with the specific reason. Failure markers are categorical, not continuous measurements — they're excluded from the agreement / outlier math (a vial that failed isn't an "unusually low purity"). They remain visible because a buyer should know a vial in this batch failed.
⇄ Weak-lot label — multiple products grouped together.
This page groups records by the vendor's batch label, but the records span 2 distinct labeled dose products (10mg, 30mg). The aggregate Content Mean / Range / CV stats above mix different products; the per-dose breakdown below is what to read instead. Vendor batch labels like calendar dates often cover multiple physical lots and SKUs.
Per-dose breakdown — the meaningful view
Within each labeled dose, content should cluster tightly around the labeled amount (with some overfill). Cross-dose averages aren't a meaningful summary of this group.

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.
