Certificate of Analysis
Every batch of our NAD+ Injection is third-party tested for identity, purity, and potency.
What to Expect
Week 1 – 2
Starting at 0.25mL once weekly — a noticeable energy lift within hours of the first injection as NAD⁺ restores ATP production. Subcutaneous delivery bypasses the conversion losses of oral precursors entirely. Many users report improved mental clarity and reduced fatigue within the first two doses.
Week 3 – 4
Titrate to 0.5mL weekly or twice weekly as tolerated. Cognitive clarity, mood stability, and physical stamina improve meaningfully. Mitochondrial function restores as NAD⁺ levels normalize across tissues, supporting the cellular energy production that declines with age.
Month 2+
Sustained cellular energy, long-term DNA repair support, and neuroprotection accumulate. Sirtuin activation and NAD⁺-driven longevity pathways compound over time. Consistent injection timing and site rotation maintains optimal plasma levels and sustained effectiveness.

What It Does
NAD⁺ is the coenzyme every cell depends on to turn fuel into usable energy. Levels fall steadily with age, and that decline tracks closely with the loss of energy, clarity, and resilience people notice in midlife. Subcutaneous injection restores it directly, bypassing the conversion losses that limit oral precursors.
NAD⁺ enhances ATP production, the energy currency powering every cell in the body. Restoring it via injection translates directly into improved stamina, vitality, and resistance to both physical and mental fatigue. This is the most immediately felt effect and often the first one users notice.
Neurons carry an enormous metabolic load, consuming a disproportionate share of the body's total energy relative to their mass. NAD⁺ fuels the mitochondrial output those cells depend on, supporting focus, memory, and mental clarity where the energy demand is highest.
NAD⁺ activates sirtuins and PARP enzymes, the primary regulators of DNA repair and cellular aging. Both consume NAD⁺ directly to do their work, which means falling NAD⁺ levels quietly reduce the body's own capacity to repair itself. Restoring it addresses aging at the cellular level.
Combats chronic fatigue and enhances recovery from both physical exertion and mental stress. NAD⁺ restores mitochondrial efficiency, addressing fatigue at its source in cellular energy production rather than masking it the way stimulants do.
Optimizes glucose metabolism, mitochondrial function, and overall energy efficiency. NAD⁺ is a required cofactor for the core enzymes that convert fuel into usable energy, improving how efficiently your body processes and uses the nutrients you give it.
NAD⁺ demonstrates neuroprotective properties, reducing oxidative stress, supporting long-term brain health, and helping defend neurons against age-related decline and environmental stressors over time.

Why Lavi MD
Most peptide suppliers prioritize volume over patients. We were built differently — by a physician, for patients.
Physician on Staff
Sasson Moulavi, MD
Dispensing Physician · Chayim Therapeutics, LLC
West Palm Beach, FL
"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.
We hold ourselves to the standards set by the bodies advancing peptide science, so you can have full confidence in every product you receive.
