Get StartedDSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first isolated in 1977. It specifically targets delta-wave sleep, the deepest and most restorative phase of your sleep cycle. Unlike sedatives, DSIP works with your body's own sleep mechanisms to improve sleep architecture, reduce cortisol, and support recovery.
DSIP may support deeper, more restorative sleep; improved sleep efficiency and onset; reduced cortisol and stress hormones; and enhanced overnight recovery. In clinical studies, it increased total sleep time by 59% and benefits persisted months after treatment. All benefits are based on published research and individual results may vary.
DSIP is administered as a simple subcutaneous injection in the evening. Typical dosing includes one injection on a provider-determined schedule. PeRx ships it fully reconstituted and ready to use. No mixing required. Insulin syringes and a step-by-step guide are included.

Sleep that actually restores you. Every night.
You log 7 or 8 hours but wake up feeling like you got 3. Brain fog, low energy, poor recovery. The problem is not how long you sleep. It is how deep.
DSIP (Delta Sleep-Inducing Peptide) targets delta-wave sleep, the deepest phase where your body repairs tissue, consolidates memory, and resets your stress hormones. In clinical studies, it increased total sleep time by 59% without the grogginess or dependence of prescription sleep aids. And unlike most sleep treatments, the improvements can last months after you stop.
Why do people explore DSIP therapy?
May increase total sleep time by up to 59% by promoting genuine delta-wave sleep, not sedation. Your brain's own sleep signals, amplified.
May help normalize cortisol rhythms so your stress-response system stops firing when it should be winding down. Fall asleep faster and stay asleep longer.
May support overnight tissue repair and muscle recovery. Deep sleep is when your body does its most important restorative work.
In clinical trials, 6 out of 7 patients maintained normal sleep for 3 to 7 months after their last dose. DSIP resets the underlying system, not just the symptoms.
No dependence, no grogginess, no tolerance. DSIP works with your natural sleep mechanisms rather than forcing unconsciousness.

DSIP vs. Melatonin
Both target sleep, but they work in completely different ways.
DSIP
Deep sleep optimization
| DSIP | Melatonin | |
|---|---|---|
| Best For | Deep sleep optimization and stress recovery | Circadian timing (jet lag, shift work) |
| How It Works | Promotes delta-wave sleep directly | Signals "time to sleep" to the brain |
| Sleep Depth | Enhances deep sleep architecture | Does not improve sleep depth |
| Duration of Benefit | 3-7 months after treatment ends | Only while taking it |
| Dependence Risk | None documented in clinical studies | None, but requires ongoing use |
Why DSIP Is Different
Melatonin tells your brain it is time to sleep but does nothing for sleep depth or quality. DSIP directly promotes delta-wave sleep and normalizes stress hormones. In clinical trials, benefits lasted 3-7 months after treatment ended.

What to Expect: Your DSIP Timeline
Every body is different, but here's the typical progression.
What you may notice:
Falling asleep feels easier. You may notice a subtle sense of calm in the evening that you were not used to. Some people report more vivid dreams in the first few nights.
What's happening:
DSIP is beginning to modulate your stress hormones and promote delta-wave sleep. Your brain is recalibrating its sleep signals.
What you may notice:
Waking up feels different. Less groggy, more alert. You may start needing your alarm again instead of waking up early. Daytime energy improves.
What's happening:
Sleep architecture is shifting. More time in deep sleep means more physical recovery, better memory consolidation, and lower baseline cortisol.
What you may notice:
Sleep feels genuinely restorative. Stress tolerance improves. Recovery from training or long days is noticeably faster. Brain fog starts to clear.
What's happening:
Your sleep-wake cycle is normalizing at a deeper level. The benefits are compounding as your body gets consistent restorative rest.
What you may notice:
Sleep quality is consistent. Many patients maintain these improvements for months after completing their protocol. You feel like a different person.
What's happening:
DSIP appears to reset the underlying sleep system rather than just masking symptoms. Most people complete their protocol or move to maintenance dosing.
More from our patients
Real experiences. Individual results may vary.
First time in years I wake up actually rested
“I was sleeping 7-8 hours but always woke up exhausted. Brain fog, low energy, terrible recovery from workouts. After 2 weeks on DSIP, I started waking up before my alarm feeling genuinely refreshed. The difference is night and day.”
Michael T.
DSIP
Finally off Ambien after 4 years
“My doctor had me on Ambien and I hated the side effects. Grogginess, weird behavior, dependence. DSIP gave me real sleep without any of that. I have been off Ambien for 3 months now and sleeping better than I did on it.”
Karen L.
DSIP
My mind finally shuts off at night
“Racing thoughts kept me up every night. I was exhausted but wired. DSIP calmed that down within the first week. I fall asleep in 15 minutes now instead of lying there for 2 hours.”
James R.
DSIP
Legitimate process, real results
“I was skeptical about online peptide therapy but PeRx made it feel like a real medical process. Provider reviewed my screening carefully, medication arrived next day. The sleep improvement has been significant.”
David W.
DSIP
Recovery from training completely changed
“As a competitive CrossFitter, recovery is everything. DSIP gave me the deep sleep I was missing. My HRV scores improved, soreness went down, and I am hitting PRs again. This is the real deal.”

DSIP Injection
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first isolated from rabbit brain tissue in 1977. It specifically targets delta-wave sleep, the deepest and most restorative phase of your sleep cycle. Unlike sedatives, DSIP works with your body's own sleep mechanisms to improve sleep architecture without grogginess or dependence.
The most commonly reported side effects are mild: slight discomfort at the injection site, temporary drowsiness (expected, given its purpose), and occasionally vivid dreams during the first few nights. No dependence or withdrawal has been documented in clinical studies, even after repeated use.
DSIP is not recommended if you are pregnant or breastfeeding, have a known allergy to DSIP or its components, or have a condition that requires careful sleep monitoring. Always disclose your full medical history during screening.
Most patients notice initial improvements within the first few nights, with sleep onset becoming easier and mornings feeling more refreshed. Full effects typically develop over 1-2 weeks. The most remarkable finding from clinical studies is that benefits often persist for 3-7 months after completing a protocol.
PeRx ships DSIP fully reconstituted and ready to use. Store refrigerated at 36-46 degrees F (2-8 degrees C). Do not freeze. Keep the vial upright and away from direct light.
DSIP is not FDA-approved for any specific condition. It is available as a compounded medication prescribed by licensed providers and prepared at FDA-registered 503A pharmacies.
No. The entire process is done online. Complete a health screening, a licensed provider reviews your profile remotely, and your medication ships directly to your door via FedEx Overnight.
Every order includes a provider evaluation and prescription, pharmacy-grade DSIP from an FDA-registered 503A pharmacy, insulin syringes, alcohol swabs, a step-by-step injection guide, and FedEx Overnight shipping.
Yes. DSIP pairs well with Selank (for reducing anxiety that interferes with sleep), Epitalon (for circadian rhythm and longevity support), and Sermorelin (which is also taken at bedtime and supports GH release during sleep). Your provider can advise on combinations.
Melatonin is a circadian signal that tells your brain it is time to sleep, but it does not improve sleep depth or quality. DSIP directly promotes delta-wave sleep, the deepest phase where physical recovery and memory consolidation happen. Melatonin requires ongoing use. DSIP benefits have been shown to persist for months after treatment ends.
