Also known as: ACTH fragment, Met-Glu-His-Phe-Pro-Gly-Pro
Semax is a short synthetic peptide built on a fragment of a natural hormone sequence, which is why some vendors label it an ACTH fragment. It sits in the nootropic category and is sold strictly as a research-use-only chemical, a lyophilized powder measured in milligrams per vial. Semax is one of the most consistently stocked names on the nootropic shelf, usually listed right next to Selank, so shoppers can often find several vendors at once.
Like most nootropic peptides, Semax comes in small vials, so the milligram content matters more than the sticker. The table above normalizes every listing to landed cost per mg, price plus shipping divided by total milligrams, the only fair way to rank a 5 mg vial against a 10 mg one.
Semax is routinely compared with Selank, and the shelf also holds Dihexa and P021. See the coupons page for an active code.
