What It Does
Six Reasons Clinicians Recommend DSIP
Delta Sleep-Inducing Peptide — a naturally occurring compound that works with your body's own rhythms to promote deep, restorative sleep without sedation or dependency.
Improves Sleep Quality
Enhances deep, restorative sleep and promotes healthy circadian rhythm regulation — so you wake up actually rested, not just having logged hours in bed.
Reduces Stress & Anxiety
Lowers cortisol levels and supports a calm nervous system response — helping your body and mind transition into a restful state naturally, without sedatives or dependency.
Supports Hormone Balance
May help normalize stress-related hormone activity, including cortisol and growth hormone regulation — supporting overall endocrine balance during sleep cycles.
Enhances Recovery
Promotes muscle and tissue repair during rest — making DSIP particularly valuable for active individuals, athletes, and anyone who needs their body to recover effectively overnight.
Improves Mood & Focus
Supports daytime alertness and mental clarity through better-quality sleep — because when your nights improve, your days follow. Customers report sharper focus and more stable mood after consistent use.
Neuroprotective Effects
Reduces oxidative stress and supports cognitive resilience — protecting neuronal health during the critical repair and consolidation processes that occur during deep sleep stages.

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.
Cortisol 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.
Deep 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.
Cumulative 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.
Why Lavi MD
Not All Peptide Brands Are Equal
Most peptide suppliers prioritize volume over patients. We were built differently — by a physician, for patients.

"Every product we offer is something I would prescribe to my own patients. Our formulations are designed for clinical outcomes — not marketing claims."
How We Operate
Built by a Physician, Not a Marketing Team
Lavi MD was founded under physician supervision. Every formulation, every dose, every protocol is reviewed by Dr. Moulavi before it reaches a patient — not outsourced to a contract manufacturer with no clinical input.
We Limit Shipping Days to Protect Your Product
We only ship Monday and Tuesday. That's a deliberate decision — it ensures your order arrives before the weekend and never sits in a carrier facility over two days without refrigeration. Most brands don't think that far ahead.
We Treat You Like a Patient, Not an Order Number
Our team includes clinical staff who understand what you're taking and why. If something goes wrong with your order — a warm shipment, a missing component, a question about your protocol — we fix it. No automated runaround.
Important — read before opening
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 the 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 prescribing physician. Most protocols call for 1 to 2 sprays per nostril once daily. Do not exceed the recommended dose without consulting your provider.
If anything appears to be missing from your order, do not discard the packaging. Contact support@lavimd.com and we will make it right.
