What drives the Selank price
Selank is a seven-residue linear peptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, formula C33H57N11O9. It is built entirely from standard L-amino acids and carries no terminal modifications, so its cost is set mainly by synthesis scale and by its proline content: three prolines in seven positions mean several slower couplings onto a secondary amine. Purification is a single preparative HPLC run for a peptide of this size. In the UK market Selank is listed in 5 mg and 10 mg vials, and the 10 mg band sits clearly below the 5 mg band per mg. Every listing recorded in this edition was in stock, so the figures describe prices a buyer could pay on the check date. For a short, unmodified chain like this, a large spread between suppliers reflects their own margins and testing more than any difference in the molecule, which makes the median a sound anchor for judging any single Selank listing.
