DSIP 10mg research vial
DSIP is delta sleep-inducing peptide, a chain of 9 amino acids first found in rabbit blood in 1977; the 10mg vial sells for 2,400,000 VND ($95 USD). DSIP's price was checked on 11 October 2026; its two sleep studies and one review all link to PubMed.
What is DSIP?
A team in Basel, Switzerland, first found DSIP in 1977, in blood taken from the brain veins of rabbits.
Despite the name, its link to sleep is far from settled. The 2006 review below notes that no gene or receptor for it has been found.
Good to know
Its full name, delta sleep-inducing peptide, is a label from the 1970s. The 2006 review calls the peptide a still unresolved riddle.
DSIP in sleep studies since 1987
- Review, 2006. A review of what is known about DSIP. It calls the peptide a still unresolved riddle, partly because no gene or receptor for it has been found.
- Human trial, 1987. 14 middle-aged people with long-term insomnia slept in a lab for 7 nights, on DSIP and on a placebo. The study scored sleep and daytime alertness.
- Human trial, 1992. A double-blind study of 16 people with insomnia measured their sleep in the lab with DSIP. Its authors concluded that short-term DSIP is unlikely to matter much for insomnia.
A few small sleep studies from the 1980s and 1990s, and a role that is still unclear.
How to read this
DSIP is a good lesson in names. It is called a sleep-inducing peptide, but the research since it was found in 1977 has not pinned down a gene or a receptor for it. The two human sleep studies are small: 14 people in 1987 and 16 in 1992, and the 1992 study was double-blind. Studies that small cannot settle what the peptide does.
The DSIP paper trail
The 1987 study ran in European Neurology and measured sleep in a lab over 7 nights, in middle-aged people with long-term insomnia. The 1992 study, in Neuropsychobiology, was double-blind, and its authors judged short-term DSIP unlikely to matter much for insomnia. The 2006 review, in the Journal of Neurochemistry, called DSIP a riddle that is still unresolved.

Questions about DSIP
What has research on DSIP looked at?
Sleep, in a few small human studies from 1987 and 1992. Its role is still unclear.
Does the name DSIP mean it causes sleep?
No. Delta sleep-inducing peptide is a name from the 1970s, given when it was found. A 2006 review called its link to sleep weak, partly because no gene or receptor for it has been found.
What is DSIP used for?
DSIP is a research peptide. Small human sleep studies in 1987 and 1992 gave mixed results, and a 2006 review called its role an unresolved riddle. The vial here is sold for lab research, not as a sleep aid.
How big is the DSIP research record?
Our PubMed search on 18 October 2026 returned 518 records for delta sleep-inducing peptide. Only two human sleep studies are listed here, and together they cover just 30 people.
