Which stores list FOXO4-DRI: 18, cheapest per mg first
#: rank by price per mg among the listings shown; a sort by another column keeps each listing's rank. Score: Finnrick's FOXO4-DRI score at that vendor and its number of tests. "overall": Finnrick has no FOXO4-DRI score there, so the vendor's overall score is shown. vs median: 0.50x is half the median price per mg. Likely listing error: far below the normal range, or out of line with the store's own sizes. Based in (Ships from column): the store's pages don't say where it ships from, so this is the location on the vendor's Finnrick profile. The "Ships from" filter counts it unless it ends in a question mark. US? (any place with a question mark): not confirmed. Finnrick gives the location with a question mark and the store's pages don't say where it ships from, so the "Ships from" filter leaves it out.
