DSIP (delta sleep-inducing peptide, emideltide): does it help you sleep, and is it safe? The positive results come from small 1980s IV studies, the two independent placebo-controlled trials found little benefit, FDA found no human data for injection under the skin, and its compounding advisers voted against it.
DSIP is a nine-amino-acid peptide first described in 1977 by a Basel lab that infused it into rabbits’ brains and saw more deep-sleep brain waves.[8] It is now sold as an injection or nasal spray for sleep. In people, the encouraging results come from a handful of small intravenous studies in the 1980s, most by the group that discovered it, while the two independent placebo-controlled insomnia trials found little or weak benefit.[13][16][17][18] FDA called the insomnia evidence “inconclusive and at best preliminary,” found no human studies of injection under the skin, and recommended against letting pharmacies compound it; its advisory committee voted 6-7-1 against.[1][3][4] The honest answer: it has not been shown to help sleep, and its safety in the forms sold today is unknown.
Why this matters now
At FDA’s Pharmacy Compounding Advisory Committee meeting on July 23-24, 2026, DSIP (listed as emideltide) was the only one of the seven peptides on the agenda that the committee voted not to add to the list of substances pharmacies may compound. The tally was 6 yes, 7 no and 1 abstention for both forms, as transcribed from the webcast; FDA has not posted minutes.[3][4][2] By PeptideBase’s transcription, all six yes votes came from members newly seated in 2026, one of whom voted no, while the longer-standing members and representatives who voted cast the other six no votes and the abstention. That pattern is our reading of the transcription, and the stated reasons are in CSPI’s member-by-member table.[3][5] FDA’s own staff had recommended against it.[1] The final call is FDA’s, and FDA’s separate interim peptide compounding policy has been under White House review since October 14, 2026, with its peptide list not public.[7] Meanwhile DSIP is promoted online for deep sleep, stress and recovery. For the wider policy, see our FDA peptide compounding explainer.
Timeline
| Date | Event |
|---|---|
| 1977 | A Basel lab publishes the peptide’s sequence and reports that infusing it into rabbits’ brains increased delta (deep-sleep) brain waves.[8] |
| 1980 | A Zurich sleep lab reports no significant increase in sleep or delta power in rats.[9] |
| 1981 | First human studies: 6 healthy volunteers and 6 people with insomnia, given IV DSIP; the authors report better sleep.[12][13] |
| 1984 | Open-label reports in insomnia, a single case of narcolepsy and 107 inpatients in alcohol or opioid withdrawal.[14][19][20] |
| 1986-1987 | Further positive insomnia reports from the same clinical investigator, without a separate placebo group.[15][16] |
| 1987 | An independent randomized placebo-controlled crossover trial finds the sleep improvement “of little clinical significance.”[17] |
| 1992 | A second independent placebo-controlled trial finds weak effects, “not likely to be of major therapeutic benefit.”[18] |
| 2006 | A review calls DSIP “a still unresolved riddle”: no gene, precursor protein or receptor has been found.[10] |
| 2009 | The last human trial we found: IV DSIP during surgery raised heart rate and reduced delta rhythm.[22] |
| 2020 | A DSIP vial is among products in a voluntary sterility recall.[28] |
| July 24, 2026 | FDA staff recommend against listing emideltide; the committee votes 6-7-1 against.[1][3] |
| October 14, 2026 | FDA’s interim peptide compounding policy goes to White House review; its contents are not public.[7] |
What DSIP is
DSIP is a short peptide, Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, made synthetically. Its drug name is emideltide, and it is sold as the free base or the acetate salt.[8][1] Despite the name, it is not clear that the body makes it as a sleep signal. Decades on, no gene, precursor protein or receptor for it has been identified, and a 2006 review called the sleep-factor hypothesis “extremely poorly documented and still weak.”[10] FDA notes that it disappears from human blood within minutes, with a plasma half-life of about 8 minutes.[1] No country searched by FDA has registered it as a drug, and there is no USP monograph for it.[1] A Russian preparation, Deltaran, combines it with glycine.[25][1]
The evidence, rung by rung
- Animals. The discovering lab’s rabbit work was positive, but other labs got mixed results, and one rat study found no significant increase in sleep or delta power.[8][9][11][1]
- Insomnia, the main claim. Four positive reports in people with insomnia or healthy volunteers came from the discovering group or its clinical collaborator, with 6 to 18 participants each, and an open-label series of 7 was also positive.[12][13][15][16][14] The two independent double-blind placebo-controlled trials, with 6 and 16 patients, found effects that were not clinically meaningful or were weak.[17][18] FDA said the studies “did not reach the same conclusions” and called the results “inconclusive and at best preliminary.”[1]
- Narcolepsy. One case report, in one man.[19]
- Opioid and alcohol withdrawal. A 1984 open-label series of 107 inpatients reported rapid improvement, but there was no control group and its authors said nothing allowed a conclusion about maintenance treatment. A 1998 open-label study of 7 people found only two completed the schedule.[20][21][1]
- Hormones and heart rate. In 8 healthy women, IV DSIP had no effect on growth hormone. In a 2009 randomized study during anaesthesia, it raised heart rate, lowered heart rate variability and, unexpectedly, reduced delta rhythm.[23][22]
- The forms sold now. Every sleep study above gave DSIP into a vein. FDA found no human studies of injection under the skin, and the only nasal study we found measured a brain-wave response, not sleep.[1][24]
- Trials today. ClinicalTrials.gov lists none, and PubMed’s DSIP output peaked in the 1980s.[26][29]
Safety: what is and isn’t known
FDA counted 209 people given IV DSIP for 1 to 15 days in the studies it found.[1] In the 107-patient withdrawal study, FDA reports, nine had minor transient effects such as sweating, headache, nausea and vertigo, and three had serious effects: two had low blood pressure at the first injection, one of whom had “progressive hypotension” after a second, and one had repeated episodes of discomfort.[1][20] FDA searched its adverse event database through March 2024 and found zero reports, and our openFDA search found none either, but unapproved products bought online are rarely reported.[1][27]
The bigger gap is what has never been studied. FDA found no human data for injection under the skin, no repeat-dose toxicology, and no studies of addiction potential, even though animal work suggests DSIP acts partly through the body’s opioid system; it also flags a possible interaction with drugs such as the blood pressure medicine captopril, which could slow its breakdown.[1] FDA describes the substance as “not well characterized,” with no endotoxin testing for injection and a risk of immune reactions to impurities or clumped peptide.[1][6] A DSIP vial was part of a 2020 voluntary sterility recall.[28] The mouse study reporting fewer tumors with Deltaran is often cited online, but FDA says that finding may not be due to DSIP at all.[25][1]
Legal status
No DSIP product is approved by FDA, and Drugs@FDA lists none.[27][1] FDA lists emideltide among compounding nominations that were withdrawn, with safety concerns.[6] The nominations were withdrawn and FDA evaluated it anyway; its staff proposed not adding either form to the 503A bulks list, and the committee voted 6-7-1 against.[1][3][4] The committee’s vote is advisory and FDA has not announced a final decision. Bulk powders are registered in FDA’s NDC directory, but a listing is not approval.[28] FDA reports that clinics, med spas and online retailers sell DSIP injections and nasal sprays; whether any given product was legally compounded is a separate question.[1]
What a careful reader should notice
These points are our analysis of the sources cited.
- The core sleep claim rests mainly on one research group’s small studies; when other teams ran placebo-controlled trials, the benefit mostly disappeared.[16][17][18][1]
- Every human sleep study gave DSIP into a vein, while the products sold now are injected under the skin or sprayed into the nose.[1][24]
- A peptide that lasts about 8 minutes in the blood is being marketed for whole nights of deeper sleep, and the mechanism has never been pinned down.[1][10]
- Claims about growth hormone and heart rate do not match the human data we found: no growth hormone effect in one study, and a higher heart rate in another.[23][22]
- No new human trial has been registered or published for years.[26][29]
- Supporters at the July meeting made a historical case from the 1970s and 1980s studies; FDA and a majority of voting members found that record insufficient for today’s uses.[3][1]
Frequently asked questions
- Does DSIP help you sleep?
- It has not been shown to. Small IV studies in the 1980s, mostly from the group that discovered it, reported better sleep, but two independent placebo-controlled trials found little or weak benefit. FDA called the evidence “inconclusive and at best preliminary.”[16][17][18][1]
- Is DSIP safe?
- No one knows for the forms sold today. About 209 people received it by vein in older studies, and a few had low blood pressure or other effects. FDA found no human data for injection under the skin and no long-term toxicology.[1][20]
- Is DSIP FDA approved?
- No. There is no approved DSIP product in the United States, and FDA found it is not registered as a drug in any country it searched.[27][1]
- Can pharmacies compound DSIP?
- FDA’s staff recommended against adding it to the list of substances pharmacies may compound, and FDA’s advisory committee voted 6-7-1 against in July 2026. The vote is advisory and FDA has not announced a final decision.[1][3][4]
- Does DSIP work as a nasal spray?
- There is no evidence it helps sleep that way. The only nasal study we found measured a brain-wave response, and all sleep studies gave DSIP into a vein.[24][1]
- Does DSIP raise growth hormone or lower heart rate?
- The human data we found do not support those claims. One study found no growth hormone effect, and a randomized study during surgery found DSIP raised heart rate. A lower heart rate was seen in rats.[23][22][1]
- Is the body’s own DSIP a natural sleep hormone?
- That remains unproven. No gene, precursor protein or receptor for DSIP has been identified, and a 2006 review called the sleep-factor idea “extremely poorly documented and still weak.”[10]
Bottom line
DSIP earned its name from rabbit experiments in 1977 and a run of small, encouraging human studies in the 1980s.[8][13][16] When independent researchers tested it against placebo, the benefit was weak or clinically trivial, and in the decades since nobody has registered a new trial.[17][18][26] FDA found the evidence inconclusive, the substance poorly characterized and no human data for the injections now sold, and its advisers voted against compounding it.[1][3] Anyone using DSIP for sleep would be relying on unconfirmed 1980s IV data for a product given a different way. FDA notes that approved insomnia treatments exist, and the professional guideline it cites recommends cognitive behavioral therapy for insomnia first.[1]
