What It Does
Six Reasons Clinicians Recommend TB-500
A synthetic fragment of Thymosin Beta-4 — a naturally occurring protein that regulates cell structure, promotes actin polymerization, and drives tissue repair. Widely used in regenerative medicine for accelerated recovery from musculoskeletal injuries and chronic tissue damage.
Accelerates Muscle, Tendon & Ligament Repair
TB-500 promotes the upregulation of actin — the structural protein essential for cell migration and tissue regeneration. This mechanism drives faster healing of damaged muscle fibers, tendons, and ligaments by recruiting repair cells to injury sites and accelerating the formation of new connective tissue. Particularly effective for injuries that have failed to heal through rest alone.
Promotes Angiogenesis & Blood Flow
TB-500 stimulates the formation of new blood vessels (angiogenesis) at injury and repair sites — improving oxygen and nutrient delivery to damaged tissue. This vascular support is critical for recovery in areas with naturally poor blood supply such as tendons and cartilage, where healing is typically slow due to limited circulation.
Reduces Inflammation & Scar Tissue
TB-500 modulates inflammatory cytokines at repair sites — reducing excessive inflammation that impairs healing and contributes to fibrosis. Unlike anti-inflammatory medications that can slow healing by suppressing the entire inflammatory cascade, TB-500 selectively reduces damaging inflammation while preserving the signaling needed for proper tissue regeneration and minimal scar formation.
Supports Joint & Cartilage Health
By promoting cell migration and tissue regeneration, TB-500 supports the repair of joint structures including cartilage, synovial tissue, and periarticular connective tissue. Research has shown meaningful improvements in joint pain and function in conditions involving degenerative joint disease and repetitive use injury — where conventional treatments offer limited regenerative benefit.
Neuroprotective & CNS Repair
Thymosin Beta-4 is expressed throughout the central nervous system and plays a role in neuronal survival and remyelination. TB-500 has been studied for its neuroprotective effects — supporting recovery from traumatic brain injury, promoting oligodendrocyte survival, and reducing neuroinflammation. These effects make it relevant in protocols addressing neurological injury and cognitive recovery.
Supports Cardiac Tissue Repair
Thymosin Beta-4 is one of the most highly expressed proteins in cardiac tissue. TB-500 has been researched for its role in cardiac repair following ischemic injury — stimulating cardiomyocyte survival, reducing myocardial fibrosis, and supporting the regeneration of heart tissue. Ongoing studies continue to explore its role in post-cardiac event recovery protocols.

Formulated by Dr. Sasson Moulavi
Every Lavi MD peptide is developed under the direction of Dr. Sasson Moulavi, the physician behind the brand. Formulations are built to clinical specification, not sourced from anonymous suppliers.
Dr. Moulavi earned his Doctor of Medicine from the University of Toronto and completed postgraduate training at McGill University in Montreal. He holds Board Certification in Anti-Aging Medicine and Bariatric Medicine, and is a member of the American Academy of Anti-Aging Medicine and the American Society of Bariatric Physicians. With over three decades of clinical experience in bariatric, family, and anti-aging medicine, he serves as Medical Director and prescribing physician for Lavi MD, overseeing formulation standards and clinical protocols.

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.
