DSIP
DSIP (Delta Sleep-Inducing Peptide) is a physician-prescribed neuropeptide therapy designed to support deeper, more restorative sleep and promote a calmer stress response, without the grogginess or dependency risks associated with conventional sleep medications.

DSIP is a naturally occurring neuropeptide that works with your body's own sleep systems rather than overriding them. Unlike sedatives that chemically suppress the nervous system to force unconsciousness, DSIP appears to modulate the neurotransmitter activity that governs deep, slow-wave sleep, the most physically restorative phase of the sleep cycle. It also interacts with the stress hormone axis, helping to reduce the elevated cortisol levels that can fragment sleep and keep the nervous system on high alert at night. The result is sleep that feels genuinely restorative, with clearer thinking and better physical recovery the following day.
DSIP was first isolated in 1974 by Swiss researchers from the cerebral venous blood of rabbits in an induced state of deep sleep. Early studies confirmed that it promoted slow-wave, or delta-wave, brain activity, the signature of the body's most restorative sleep phase. Research interest expanded significantly through the 1980s, with studies conducted in both Europe and Russia examining its effects on sleep disorders, stress response, and neuroendocrine regulation.
A double-blind trial in chronic insomnia patients found improvements in sleep efficiency and reductions in the time it took to fall asleep compared to placebo. The majority of existing research is preclinical or early-stage, and large-scale human trials remain limited. What is established is that DSIP is endogenous, meaning the body produces it naturally, and that its effects appear to be modulatory rather than sedating, making it a distinct category from conventional sleep aids.
Reported side effects of DSIP are generally mild and infrequent, based on available clinical and research data. The most commonly noted include mild headache, transient fatigue, and occasional dizziness following administration. As with all physician-prescribed therapies at AIRA, your clinician will review your health history and monitor your response to minimize any risk.

Frequently asked questions
DSIP has not been approved by the U.S. Food and Drug Administration. It can only be prescribed through licensed clinicians where state law allows.
Yes, though the evidence base is still developing. A double-blind clinical study in patients with chronic insomnia found that DSIP improved sleep efficiency and shortened the time needed to fall asleep compared to placebo. Additional human studies have examined its effects on the stress hormone system and neuroendocrine regulation. Most of the broader research on DSIP comes from preclinical work and early-stage European and Russian studies conducted primarily in the 1980s and 1990s.
DSIP appears to support deeper, more restorative sleep by modulating the brain activity associated with slow-wave sleep, the phase where the body does most of its physical repair. It also appears to interact with the body's stress hormone system, helping to reduce nighttime cortisol elevations that can disrupt sleep quality and leave you feeling wired when you should be winding down. Its effects are regulatory rather than sedating, meaning it works with your body's natural processes rather than forcing sleep artificially.
Based on available research, DSIP appears to be well-tolerated at clinical doses, with a mild side effect profile. Because research is still evolving, use under the guidance of a licensed physician is essential. Your AIRA clinician will assess your health history before prescribing and can adjust your protocol based on your individual response.
DSIP is not recommended for individuals who are pregnant or breastfeeding. It may also be unsuitable for those with certain hormonal conditions, a history of hormone-sensitive conditions, or known sensitivities to peptide compounds. Your prescribing clinician will review your full health history to determine whether DSIP is appropriate for you.
DSIP is administered via subcutaneous injection, typically in the evening. Your AIRA clinician will determine the appropriate protocol based on your individual health goals and response. AIRA does not provide specific dosing guidance on this page; all protocols are determined by your prescribing physician.
DSIP may be used alongside other peptide therapies, depending on your overall protocol and health goals. It is sometimes considered alongside compounds that address related concerns, such as stress regulation or hormonal balance. Your AIRA clinician will evaluate whether any combination is appropriate for your specific situation and health history.
