DSIP Nasal Spray
Everything You Need to Know
DSIP -- Delta Sleep-Inducing Peptide -- is a naturally occurring compound that promotes deep, restorative sleep without sedation or dependency. It works with your body's own rhythms rather than overriding them.
- Reduces Stress & Anxiety - Supports focus, memory, and mental clarity.
- Reduces Stress and Anxiety - Lowers cortisol and supports a calm nervous system response.
- Supports Hormone Balance - May help normalize stress-related hormone activity.
- Enhances Recovery - Promotes muscle and tissue repair during rest.
- Improves Mood and Focus - Supports daytime alertness and mental clarity through better-quality sleep.
- Neuroprotective Effects - Reduces oxidative stress and supports cognitive resilience.
DSIP is ideal for anyone experiencing poor sleep quality, difficulty falling asleep, stress-related insomnia, or disrupted sleep cycles. Particularly well-suited for individuals who want to improve their sleep naturally -- without relying on melatonin, sedatives, or habit-forming sleep aids.
Melatonin signals your body that it's dark outside. Sedatives suppress your nervous system. DSIP does neither -- it works at a deeper level by reducing cortisol, supporting the HPA axis, and enhancing the quality of slow-wave sleep your body already produces. No rebound insomnia. No next-day grogginess. No dependency.
Yes. DrSeinfeld.com DSIP Nasal Spray is non-steroidal and contains no toxic fillers or preservatives. Each batch is micro-filtered in our SQF-certified, FDA-registered compounding facility under the oversight of Dr. Amy Seinfeld, D.O. - formulated for consistent purity and potency.
Administer 1 spray into each nostril approximately 30 to 60 minutes before bedtime. Lay down immediately after administration to enhance absorption. May be used up to twice nightly - max 4 total sprays per 24-hour period. Use consistently for best results.
DSIP nasal spray is generally well tolerated. Mild side effects may include temporary nasal irritation or dryness, mild drowsiness if taken too early in the evening, vivid dreams during the first few nights, or rarely a mild headache. These effects are typically short-lived and resolve without intervention.
Administration Protocol
Storage & Handling

The Science
How DSIP Works Inside Your Body
Unlike melatonin or sedatives that force sleep, DSIP works with your body's natural sleep-wake architecture -- enhancing the quality and depth of sleep you're already capable of.
Nasal Administration - 30 to 60 Minutes Before Bed
Administer 1 spray into each nostril approximately 30 to 60 minutes before bedtime. The nasal mucosa absorbs DSIP rapidly -- bypassing the digestive system and entering the bloodstream without first-pass metabolism. Lay down immediately after administration to maximize absorption.
Bypasses digestion -- faster onset than oral sleep aidsCortisol Reduction & Nervous System Calming
Once absorbed, DSIP helps lower cortisol -- the primary stress hormone that keeps the nervous system in an activated state. By modulating the HPA axis, DSIP supports the physiological transition your body needs to enter and sustain deep sleep stages.
Cortisol reduction -- nervous system regulationDeep Sleep Stage Enhancement
DSIP promotes deeper slow-wave sleep -- the stage where physical recovery, hormone regulation, and memory consolidation occur. Unlike sedatives that suppress sleep architecture, DSIP enhances its natural depth and quality without blunting REM cycles.
Slow-wave sleep -- no REM suppressionCumulative Sleep Regulation
With consistent nightly use over 4 to 8 weeks, DSIP helps recalibrate your body's circadian rhythm and sleep-wake cycle. Most customers report noticeable improvements within the first few nights, with sustained deeper sleep and improved daytime function building over the full protocol.

Before You Use Your Nasal Spray
Your spray ships in two parts. Take 60 seconds to assemble before first use.
Check Your Package Contents
Your nasal spray ships in two parts: the bottle and the pump mechanism. Both are inside the box, protected by inner packaging. Do not discard anything until you have located both pieces.
Do not throw away any packaging until you have fully assembled your spray.Remove the Protective Cap From the Pump
Locate the pump mechanism inside the box. It will have a small protective cap covering the nozzle tip. Remove it and set it aside - you will reuse it to seal the spray between doses.
Attach the Pump to the Bottle
Insert the pump stem into the top of the bottle and press down firmly until it clicks into place and sits flush with the bottle neck. The pump should feel secure and not wobble.
Prime Before First Use
Hold the bottle upright and depress the pump 3 to 5 times until a fine mist appears. This purges any air from the stem. Your spray is now ready to use.
Prime into a tissue - not toward yourself or others.Replace the Cap and Refrigerate
After each use, replace the protective cap over the nozzle. Refrigeration is required. Store upright in your refrigerator away from strong odors. Do not freeze.
Recommended Usage
Use only as directed by your healthcare provider. Most protocols call for 1 to 2 sprays per nostril once daily in the morning. Do not exceed the recommended dose without consulting your provider.
