What It Does
A calming peptide for stress resilience, emotional balance, and clear-headed focus, delivered via nasal spray for rapid absorption.
Selank interacts with the GABA system, which is involved in the body's stress response, to support a calmer, more balanced state without sedation or dependency.
Provides calming support without drowsiness or impaired alertness, so you stay clear-headed rather than foggy.
May support emotional stability and resilience through demanding periods, without the highs and crashes of stimulant-based options.
Studied for its role in supporting concentration and mental clarity, helping you stay composed and on task under pressure.
Helps the body adapt to everyday stress, supporting a steadier response to demanding situations over time.
A peptide-based approach studied for tolerability, absorbed through the nasal pathway without the jitters, crashes, or dependency of stimulants.

The Science
Nasal delivery bypasses the digestive system entirely, so active compounds reach the bloodstream faster and more efficiently than capsules or oral drops.
You administer 1 spray into each nostril. The nasal mucosa, a highly vascularized membrane, immediately begins absorbing the peptide. No swallowing, no waiting for digestion.
Selank enters the bloodstream directly through the nasal mucosa within minutes. Some is also absorbed via olfactory pathways, giving the central nervous system near-direct access, something oral formats cannot match.
Selank engages the GABA system, modulating the body's stress-response pathways and supporting a calm, balanced state at a molecular level, without sedation or dependency.
With consistent daily use over 4 to 8 weeks, peptide levels build for steady support. Most people notice initial effects within 1 to 2 weeks, with calm, stress resilience, and focus continuing to develop over time.
Why Lavi MD
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
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.
