What to Expect
Week 1 – 2
Improved cellular energy efficiency and a noticeable lift in physical stamina. AMPK activation begins shifting metabolism toward fat utilization and mitochondrial efficiency. Some users notice improved workout performance and faster recovery within the first two weeks of weekly dosing.
Week 3 – 6
Insulin sensitivity improves and metabolic flexibility builds. The body becomes more efficient at switching between fat and carbohydrate fuel sources. Physical endurance and resilience under stress improve meaningfully. Mood and vitality stabilize as mitochondrial function normalizes.
Month 2+
Long-term mitochondrial protection and anti-aging benefits accumulate. Oxidative stress decreases, cellular stress adaptation improves, and the metabolic optimization effects of consistent MOTS-c signaling compound over time as part of an ongoing longevity protocol.

What It Does
A naturally occurring peptide encoded within your own mitochondrial DNA — functioning as a metabolic master switch and exercise-mimetic that regulates cellular energy, insulin sensitivity, and stress adaptation. MOTS-c levels decline significantly with age, making supplementation an increasingly central longevity strategy.
A Peptide Encoded in Your Own Mitochondrial DNA
Unlike synthetic peptides developed in a lab, MOTS-c is a naturally occurring peptide your body already produces — encoded within the mitochondrial genome itself. This makes it one of the only known peptide hormones with a mitochondrial origin, functioning as a fundamental communication signal between mitochondria and the rest of the body. Supplementing MOTS-c restores a signaling system your cells are already designed to respond to.
MOTS-c activates AMPK — the cell's primary energy-sensing enzyme and metabolic master switch. AMPK activation shifts cells into an energy-efficiency mode: increasing glucose uptake, enhancing fat oxidation, and upregulating mitochondrial biogenesis. The result is more energy produced per unit of fuel consumed — improved cellular efficiency that translates directly into sustained physical and mental energy throughout the day.
MOTS-c encourages fatty acid oxidation — shifting the body's energy preference toward stored fat as fuel while also regulating glucose metabolism. This dual fuel optimization supports healthier body composition, improved metabolic balance, and more efficient energy utilization during both exercise and rest. Research shows MOTS-c reverses age-related and diet-induced metabolic dysregulation that drives fat accumulation despite adequate exercise.
Often called an "exercise-mimetic," MOTS-c mimics many of the metabolic adaptations produced by physical training — increasing mitochondrial efficiency, improving fat utilization during activity, and reducing exercise-induced oxidative stress. Studies demonstrate meaningful improvements in endurance, stamina, and recovery in subjects treated with MOTS-c — making it valuable both as a performance-enhancing tool and as a recovery accelerator between training sessions.
MOTS-c significantly improves insulin sensitivity — enhancing glucose uptake in skeletal muscle and reducing the insulin resistance that drives metabolic syndrome, pre-diabetes, and obesity-related disease. Research has shown MOTS-c reverses age-related and diet-induced insulin resistance. Its mechanism is distinct from and complementary to GLP-1 based approaches — working at the mitochondrial and cellular metabolism level rather than through appetite suppression.
MOTS-c levels decline progressively with age — mirroring the metabolic and physical decline associated with aging — and are significantly higher in long-lived individuals including centenarians. In aging animal models, MOTS-c supplementation extends lifespan, improves healthspan markers, and reverses multiple age-related metabolic dysfunctions. It protects against oxidative stress and age-related mitochondrial decline — two of the primary hallmarks of biological aging.
Beyond physical performance, MOTS-c supports the cellular stress adaptation pathways that govern mood, mental resilience, and overall vitality. By activating the integrated stress response and upregulating antioxidant defense, MOTS-c helps cells adapt to and recover from physiological and environmental stressors — translating into improved mood stability, sustained mental energy, and greater overall resilience under the physical and psychological demands of daily life.

The Science
MOTS-c is released by your own mitochondria in response to metabolic stress — acting as an intercellular signal that coordinates a body-wide metabolic adaptation response. Supplementing MOTS-c amplifies this signaling system, producing the metabolic benefits of intense exercise without the physical demand.
Inject 0.1mL to 0.2mL (dial to 10 or 20) subcutaneously into the abdomen or upper thigh. Rotate injection sites weekly. Slight burning or tingling at the injection site is normal and reflects MOTS-c's activity at local tissue. MOTS-c is administered weekly or monthly as part of a metabolic optimization or longevity program — with frequency determined by your physician based on goals and response.
Once in circulation, MOTS-c translocates to the nucleus and activates AMPK — the cell's primary energy-sensing kinase that functions as the metabolic master switch. AMPK activation triggers a cascade: mitochondrial biogenesis increases, fatty acid oxidation accelerates, glucose uptake in muscle tissue improves, and unnecessary anabolic processes that consume energy are downregulated. This is the same metabolic shift that occurs during sustained aerobic exercise — produced at the cellular signaling level without the physical demand.
MOTS-c functions as a mitochondrial stress signal — activating the integrated stress response (ISR) that coordinates cellular adaptation to metabolic, oxidative, and physical stressors. This includes upregulation of antioxidant defense pathways, improvement of mitochondrial quality control, and enhancement of the cell's ability to survive and function efficiently under demanding conditions. The net effect is greater systemic resilience — metabolically, physically, and immunologically.
With consistent weekly or monthly dosing as part of a metabolic or longevity program, MOTS-c's effects compound over time — progressively improving insulin sensitivity, mitochondrial function, and cellular stress resilience. MOTS-c levels are significantly higher in centenarians than in average aging adults, and animal studies show lifespan extension with supplementation. The long-term protocol is designed to maintain the mitochondrial signaling that naturally declines with age, supporting healthspan alongside lifespan.
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

"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.
