Picks come from vendors with Finnrick lab tests and leave out listings the store marks out of stock; a listing that doesn't state its stock can be picked. The table below has every listing. A lab score describes the purity and dose of past samples. It doesn't mean a product is safe or suitable for any use.

One row per vial size with a listing that can be ordered: likely listing errors, prices far above other stores and listings the store marks out of stock are left out (a listing that doesn't state its stock counts). Stores: how many sell that size in any pack. A kit's price is for the whole pack.

Which stores list LL-37: 22, 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 LL-37 score at that vendor and its number of tests. "overall": Finnrick has no LL-37 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. * Count assumed: the listing gives no vial count, so it is counted as 10 because it says "kit" or the store sells only 10-vial kits. Sale, was: the store's own listing marks the price as reduced; "was" is its regular price. Shown only for 5% to 50% off, when the regular price per mg is no higher than the highest price per mg any store here asks for that peptide and pack type, this store included. A store that marks over 4 in 5 of its listings reduced gets no tag, and nor does a group of 5 or more single vials, or of packs, with over 4 in 5 marked (exact rule).
