Overview
DSIP, or delta sleep-inducing peptide, is a nine-amino-acid peptide. Early experimental work identified the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu and established DSIP as a named research peptide.
Each vial contains 10 mg of DSIP peptide. The material is supplied for research use only and is not a medicine or a product intended for human or animal use.
Mechanism and research
The original DSIP publication characterised the nonapeptide and examined EEG activity in an animal model. It compared the synthesised sequence with related fragments and analogues, making molecular identity an important part of interpreting the experiment. The historical name comes from this early line of research.
DSIP research concerns experimental neurophysiology. The name does not establish a sleep benefit for the material offered here, and results from a particular experimental model cannot be transferred directly to people.
Strength and packs
Choose one vial for 10 mg total content, two vials for 20 mg, or three vials for 30 mg. Each individual vial remains 10 mg.
The strength identifies the contents of one vial. Pack count identifies the number of vials selected for the laboratory inventory.
