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.
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 nearly identical (32.2 to 35.8 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.
