DSIP 5mg

DSIP 5 mg: research material

Buy DSIP 5 mg for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial.

DSIP stands for delta sleep-inducing peptide. It is a nonapeptide, meaning it contains nine amino-acid residues, used in experimental neurophysiology research.

Choose the material and presentation

The reference sequence is Trp–Ala–Gly–Gly–Asp–Ala–Ser–Gly–Glu, abbreviated WAGGDASGE. Sequence variants and modified analogues are separate materials. This product is supplied as dry powder, not as a prepared nasal spray or a sleep medication.

Other presentations: DSIP 10 mg.

DSIP research: the measured endpoint matters

The original characterization compared synthetic DSIP with related peptides in blinded rabbit experiments and reported changes in EEG activity. EEG records electrical activity; that endpoint needs to be distinguished from a broad claim about sleep quality.

A later blinded rabbit study, using a different administration method and slow-sleep assessment, found no statistically significant difference from its comparison conditions. These studies illustrate why the name alone cannot establish a reliable effect across models. Neither is evidence that this product treats human insomnia.
