DSIP
DSIP is a peptide that is research only, not approved for human use in the US.
Also known as Delta sleep-inducing peptide, Emideltide
DSIP is a nine-amino-acid peptide first isolated from rabbits in the 1970s and named for its apparent effect on deep sleep. It is sold as a research peptide for insomnia and stress.
Not approved for human useNot approved for human use in the US. We list it so you can learn what it is, but we do not link to anyone selling it. If you are considering it, a clinician can talk through approved alternatives.
Is DSIP legal in the US?
Not approved for human use in the US. We list it so you can learn what it is, but we do not link to anyone selling it. Not FDA-approved. It left the Category 2 compounding list in April 2026, but FDA's advisory committee voted 6-7 against adding it to the 503A bulks list in July 2026, so no lawful compounding route is expected.
As of September 23, 2026.
Key takeaways
- DSIP is a "sleep peptide" first found in rabbits in the 1970s. It is not approved for human use.
- Human sleep studies were small and inconclusive.
- In July 2026, the FDA advisory committee voted against adding it to the compounding list, the only peptide rejected at that meeting.
- FDA reviewers flagged a possible addiction risk and drops in blood pressure.
How does DSIP work?
Proposed from lab and animal studiesPreclinical only: in animals, DSIP seems to promote sleep in a way that depends on the body's opioid system. It does not bind opioid receptors directly but appears to trigger endorphin release.
Decades after its discovery, its natural role in human sleep is still unclear.
What does the evidence say about DSIP?
Animal & lab studies onlyMostly animal work; a small number of human studies decades ago gave inconsistent results, and its natural role in sleep is still unclear.
Why are clinicians and regulators cautious about DSIP?
Regulators concluded the evidence does not support DSIP, and flagged risks that are specific to how it seems to work.
FDA's July 2026 briefing document described the insomnia studies as inconclusive and at best preliminary, with small samples and poor controls.
FDA briefing document for the July 2026 advisory committee: emideltide (DSIP)FDA reviewers noted that stimulating the opioid system could lead to addiction, and no studies have tested its addictive potential.
FDA briefing document for the July 2026 advisory committee: emideltide (DSIP)Older human studies reported headache, nausea, vertigo and falling blood pressure. FDA also flagged a possible risk of immune reactions.

Who should avoid DSIP?
Especially important to avoid if
- Anyone taking opioids, sedatives or sleep medication, or with a history of substance use disorder
- People with low blood pressure
- Anyone considering buying it online: it is not made to drug standards
- Pregnancy or breastfeeding: there are no data
What are the risks and side effects of DSIP?
- Not approved for human use. Products sold online as "research chemicals" are not made to drug standards, so identity, purity, sterility and dose are unverified.
- FDA flagged immunogenicity risks and insufficient safety information.
- Unregulated injectables carry a risk of infection and contamination.
What should you ask a clinician about DSIP?
- What proven treatments, including CBT for insomnia, fit my situation?
- Should I be screened for sleep apnea or another sleep disorder?
These save with the compound when you add it to My Journal, so they’re on the printout for your visit.
Where can I get DSIP?
DSIP is not approved for human use, so DiscoverMedica links to no seller.
We don’t link to sellers of research-only compounds. Products sold “for research use only” are not made for people and are not held to pharmaceutical quality standards.
Compare and learn
DSIP: questions, answered
Does DSIP help insomnia?
The human evidence is small, old and inconclusive. Proven options include cognitive behavioral therapy for insomnia and treating conditions like sleep apnea.
Could it become available through compounding?
It looks unlikely. The FDA advisory committee voted against it in July 2026.
Can I get it from a telehealth provider?
No. DSIP is not FDA-approved and has no lawful compounding route, so there is nothing a licensed telehealth provider can legitimately prescribe. If a site offers it, treat that as a warning sign. DiscoverMedica does not link to anyone selling it.
What does "research use only" mean?
It means the product is not made or tested for people. FDA has sent warning letters to sellers who use that label while making health claims, and says it judges a product by how it is marketed, not by the disclaimer.
