Sequence, molecular data, research status and testing standards for DSIP, written for Canadian researchers.
DSIP (delta sleep-inducing peptide) is a nine-amino-acid neuropeptide first isolated from rabbit brain in the 1970s. It was named after the delta-wave sleep pattern seen in the original experiments.
DSIP was discovered by Swiss researchers in 1977 and has since been studied in sleep and stress research. Its exact role in the body is still not well understood, and results across studies have been mixed.
What it is: A short natural chain first found in rabbit brains.
The plain-English story: First found in rabbit brains during sleep experiments and named for sleep. It is a short chain, and a famous mystery: nobody is quite sure what role it plays. Small studies on sleep and stress have given mixed results, so treat the legend with a pinch of salt.
What it does in the body: It was named for a link to deep sleep, but how it works is not clear.
What researchers are looking at: Small studies on sleep and stress, with mixed results.
The catch (where it stands in Canada): Not an approved medicine in Canada, so nobody can legally sell it to you as one.

DSIP (delta sleep-inducing peptide) is a nine-amino-acid neuropeptide first isolated from rabbit brain in the 1970s. It was named after the delta-wave sleep pattern seen in the original experiments. It is also known as Delta Sleep-Inducing Peptide.
DSIP is not authorized by Health Canada as a drug, so it cannot legally be sold for human or animal use in Canada. This is general information, not legal advice.
It is not authorized for human or animal use in Canada, and products sold online cannot be verified without a lot-matched third-party Certificate of Analysis.
All three are neuropeptides studied in brain and stress research, but they are different molecules. Selank is derived from tuftsin and Semax from a fragment of ACTH, while DSIP was first isolated from rabbit brain.
