The order is the editors' score, not the price, because the cheapest untested vial is not a bargain. The listing shown is each shop's 10 mg single-vial price, the size most shops carry; where a shop does not stock that size we show its nearest listing and say so. Prices were read during our October 2026 check, before coupons and shipping. Every listing is sold for laboratory research use only.

Questions
Who is the best Semax supplier?
Licensed Peptides, on our formula: 8.2 out of 10, the highest score among the 38 shops that list it. Licensed Peptides names two accredited laboratories and keeps three separate document libraries, which puts it near the top of our index for paperwork. The score is the same one we give the shop everywhere on this site; nothing is reweighted for the peptide.
Who sells Semax cheapest at 10 mg?
Alpha Peptides, at $21.88 for 10 mg against a typical $38.09. It scores 6.7, so the saving comes from a shop we rate well. The price page lists every size and every shop.
Which Semax suppliers show a certificate on the product page?
16 of the 38: Ascension Peptides, Core Peptides, Paramount Peptides, Koi Peptides, Sports Technology Labs, Alpha Peptides, Alpha Labs Peptides and Peptide Warehouse and 8 more. A certificate on the page is the least a shop can do; a lot number on it that matches the vial is the thing to check, and our lab-report guide shows how in five minutes.
