Best Semax prices
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.
Wholesale and bulk: 10-vial kits. 25 stores sell Semax in 10-vial kits. Lowest price per mg in a kit: 10 x 10 mg for $60.00 at Uther ($6.00 a vial, $0.60/mg).
Ships to Canada: 14 of these 43 stores (their own shipping pages say Canada or worldwide). Ships from the US: 22 stores (a US warehouse or origin).
The "same listings" line follows only listings present on consecutive days, so stores joining or leaving don't move it; it ends at today's median.
Which stores list Semax: 43, 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 Semax score at that vendor and its number of tests. "overall": Finnrick has no Semax 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. Size unclear: the listing's size is not stated, or its own page or store data gives a different one; treated like a likely listing error. 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. 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).

How these prices are calculated
Each price is the store's public list price on the day shown, divided by the total milligrams in the pack (milligrams per vial times vials), converted to US dollars at European Central Bank rates.
