Semax / Selank prices

19 sellers, 22 listings, 4 vial sizes, read from each store's public product feed on 2026-09-30. A seller with a recent certificate from a named lab ranks above a cheaper one without. Every card says why it sits where it does. The price is the total for the vial. A blend is not priced per milligram of one peptide inside it.

2 public certificate files we opened name Semax / Selank. That is a count of files, not a grade, and compounds are not ranked against one another. A seller-published certificate is not a blind test. Certificate search.

Some seller links may pay this site when you buy through them. A payment never changes a seller's tier or rank, and no seller has a say in any page.

How the ranking works

LC
Lab-confirmed: the issuing laboratory echoed this certificate back
A
Current certificate, independent laboratory named, laboratory not yet checked
B
Certificate published, but no laboratory link, older than a year, or the laboratory did not recognise the published lookup
C
No certificate could be read
  • Grade first, then the total price of the vial within the grade. A cheap vial that is not the blend is not cheap, so no price moves a seller above a better certificate. Sort by vial price if you want price alone. The grade stays on the card.
  • The grade is what we could read on the seller's site on the date shown, not what the seller claims. If a login page or a robot block hid the certificates, the card says so. A later check in a normal browser may raise that grade.
  • Prices are list prices before any discount code, shipping, tax or customs. A pack that can be read is counted at its total milligrams. The figure on the card is the price of that amount, not a price per milligram of one peptide.
  • The dot on each card shows where that vial price sits between the cheapest and the priciest seller of the same size. The tick is the middle price. Compare the same size. A blend is not given a price per milligram.
  • Every seller links to its own page: the company behind it, address, store platform, labs named, a sample certificate, shipping and payment terms, and every warning sign we found.

We never charge for knowledge. No vendor has a say in what a page says. Sellers are ranked by the certificate they publish, then by price. Every seller, graded · Laboratories named · How this is counted
