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 HK Peptides.
Not enough data to compare
These labs did not report enough overlapping numbers to line up cleanly.
On the actual amount per vial, the labs were far apart (22.0 to 32.2 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 HK Peptides batch Rt30 · 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 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.
Purity agrees, content diverges. Labs converge on purity (spread 0.15pp) but disagree on the actual amount (range 22.0–32.2 mg, CV 18.8%). The compound is what it claims to be — but how much is in the vial varies measurably between labs.
⇄ 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 (20mg, 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.
