UTHER

TitrateLab does not rank or recommend vendors; it reports what independent labs measured. UTHER shows high measured purity (99.4% mean across 1160 positive purity measurements; 4 identity failures reported separately). Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 170 of 678 dose results were on target, 5 under label and 503 over; all time 260 of 1006 on target, 10 under and 736 over. These results describe tested batches, not every product or shipment.

99.4% mean measured purity across 1160 positive third-party lab results; 1156 were at or above 90% and 4 were below. In 4 additional tests, the labeled compound was not detected.

1485 third-party certificates from 2024-05-15 to 2026-08-31, covering 127 compounds. 5 duplicate certificates were excluded from the counts.

Dose accuracy is mixed and recent underfills are uncommon: in the last 12 months 170 of 678 dose results were on target, 5 under label and 503 over; all time 260 of 1006 on target, 10 under and 736 over. A dose result compares the measured amount with the amount printed on the label: under is more than 10% below, over is more than 10% above, on target is everything in between. Finnrick results are excluded because that lab measures against the vendor's batch claim. Missing values are never counted as passes.

Endotoxin was reported on 57 of 1480 counted records (3.9%). 12 of 57 classifiable results failed and 3 were borderline. Coverage is too limited for a vendor-wide conclusion.
