Score is Finnrick's score for TB-500 at that vendor, with the number of tests; "overall" means Finnrick has no TB-500 score there, so the vendor's overall score is shown. Not listed: Finnrick doesn't list the domain for the brand it uses. vs median: 0.50x is half the median price per mg. Likely listing error: far outside the normal range, or out of line with the store's own sizes. * The listing gives no vial count; counted as 10 because the store sells it as a kit or sells only 10-vial kits.
