TB-500
A synthetic peptide — a fragment of thymosin beta-4 — studied for its role in supporting tissue recovery, flexibility, and the body’s response to inflammation.
A peptide studied for recovery and flexibility
TB-500 is a synthetic fragment of thymosin beta-4, a protein found naturally throughout the body’s tissues. In research settings it has been studied for its potential role in supporting tissue recovery, flexibility, and the regulation of inflammation. At Meridian it is offered as a compounded medication — meaning it is prepared by a licensed pharmacy — and is used only under a provider’s guidance.
Supporting the body’s repair signals
Research suggests TB-500 may influence the cellular processes involved in tissue repair — including the movement of repair cells toward areas of injury. It is typically administered as a subcutaneous dose, often weekly, over a defined cycle.
- ✓May support cell migration — the movement of repair cells to injured tissue
- ✓Studied in the context of muscle, tendon, and connective-tissue recovery
- ✓Delivered as a provider-guided weekly protocol over a set cycle
What people explore it for
Areas of interest reported in research and clinical use. Benefits vary by individual and are not guaranteed — your provider can set realistic expectations for you.
Tissue recovery
Studied for supporting the body’s natural repair of muscle and connective tissue after strain.
Flexibility & mobility
Explored by people seeking more comfortable movement and range through recovery.
Inflammation research
Investigated in the context of how the body regulates its inflammatory response.

People who may find it relevant
Recovering from strain
Working back from a soft-tissue injury, overuse, or a persistent nagging issue.
Training intensively
Placing heavy, repeated demand on muscles, tendons, and joints.
Seeking flexibility
Exploring options for mobility and range of motion alongside a provider.
This is general education, not medical advice. Whether TB-500 is appropriate for you is determined by a licensed provider.
Why oversight matters here
This is a compounded medication, so a licensed provider must confirm it’s appropriate for you before it can be dispensed. The review checks your health history, current medications, and goals to ensure it’s a safe fit.
This therapy requires review by a licensed provider before it can be dispensed. You’ll complete a short online visit; a provider evaluates whether it’s appropriate for you and, if so, authorizes it.
Your care journey, step by step
From first visit to follow-up — calm, transparent, and guided by a licensed provider throughout.
What the research explores
A plain-language look at the areas of study. Research is evolving and varies in strength — we present it honestly, not promotionally.
Preclinical studies have explored TB-500’s effects on muscle and connective-tissue repair. Human evidence remains limited and ongoing.
Much of the early research examined thymosin beta-4’s role in helping repair cells move toward injured tissue in animal models.
Studies have investigated its potential influence on how the body regulates its inflammatory response during healing.
TB-500 is not FDA-approved. It is a compounded medication; the research base is early and evolving.
Our Science Library — evidence summaries, mechanisms, limitations, and provider commentary — is expanding.
TB-500, answered
No. It is a compounded medication prepared by a licensed pharmacy, not an FDA-approved drug. It is provided only when a licensed provider determines it is appropriate for you.
Typically as a small subcutaneous injection, often weekly, over a defined cycle. Your provider will give you specific dosing guidance and everything needed to administer it.
Yes. This therapy requires provider review. You’ll complete a short free online visit, and a provider decides whether to authorize it.
For ongoing recovery goals, membership adds check-ins, tracking, and provider adjustments over time — but it isn’t required for a reviewed purchase.
Others in Recovery
Often considered alongside TB-500 as part of a personalized recovery strategy. Your provider determines whether any therapy is appropriate based on your goals and medical history.
