What to Expect
Days 1 – 3
A subtle sense of calm within 30–60 minutes of your first dose. Stress feels more manageable. Some users notice reduced mental chatter and a lighter emotional state almost immediately.
Week 1 – 2
Sharper focus and faster mental processing. Anxiety and stress responses feel more muted. Many users report improved mood stability and a greater sense of emotional resilience throughout the day.
Week 4 – 8
Sustained cognitive clarity, improved learning and memory retention, and significantly reduced baseline anxiety. BDNF-driven neuroplasticity accumulates — supporting long-term mental performance and neuroprotection.

What It Does
A dual-peptide formula engineered for cognitive performance, stress resilience, and neuroprotection — delivered via nasal spray for maximum bioavailability.
Semax stimulates BDNF — brain-derived neurotrophic factor — to support neuronal growth, plasticity, and memory consolidation. Expect sharper focus and faster recall.
Selank modulates the GABAergic system to reduce emotional tension and regulate the stress response — without sedation or dependency.
May improve emotional stability, mental resilience, and sustained motivation throughout the day — without the highs and crashes of stimulant-based supplements.
Promotes growth and maintenance of neural pathways involved in learning — particularly effective for information retention and mental performance under pressure.
Provides calming and cognitive benefits simultaneously — without drowsiness or impaired alertness. Designed for active, demanding periods of the day.
Protects neurons from oxidative stress, reduces neuroinflammation, and supports recovery from cognitive fatigue — promoting long-term brain health.

The Science
Nasal delivery bypasses the digestive system entirely — active compounds reach the bloodstream faster and more completely than any capsule or oral drop.
You administer 1 spray into each nostril. The nasal mucosa — a highly vascularized membrane — immediately begins absorbing the active peptide compounds. No swallowing, no waiting for digestion.
Peptide compounds enter the bloodstream directly through the nasal mucosa within minutes. Some are also absorbed via olfactory pathways, giving the CNS near-direct access — something oral formats simply cannot achieve.
Semax binds to neurotrophin receptors, triggering BDNF release and enhancing neuronal signaling. Selank engages the GABAergic system, modulating anxiety pathways and stabilizing the stress response at a molecular level.
With consistent daily use over 4 to 8 weeks, peptide concentrations build to therapeutic levels. Most customers notice initial effects within 1 to 2 weeks — with cognitive clarity, reduced stress response, and improved mood continuing to improve 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 Ship 2-Day Air, Monday & Tuesday Only
We only ship Monday and Tuesday, and every order placed in that window goes out 2-Day Air. That's a deliberate decision. It keeps your order moving quickly and arriving before the weekend, instead of sitting in a carrier facility for days. 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.
