For Research Use OnlyDSIP – 15mg
DSIP is a nine-residue peptide first isolated in the 1970s from work on sleep-related factors in rabbit cerebral venous blood. Supplied lyophilised at 15mg per vial, which is $4.00 per mg. Its literature is older than most of this catalogue and correspondingly sparse by modern standards, with much of the primary work predating the analytical methods now taken for granted — a reason to read specific claims carefully rather than to dismiss them outright. Nine residues is a short synthesis, so confirm identity by mass spectrometry and check the fill weight rather than hunting subtle impurities. Research use only.
