TB-500 was recently removed from the FDA's Category 2 restricted list and is under review for inclusion on the FDA's 503A Bulk Drug Substances List following the agency's July 2026 advisory committee meeting. Until that determination is final, this page is educational only and does not represent a treatment currently available through Zvia.

When Your Body Can't Keep Up with Your Life

Whether it's a nagging injury that won't fully resolve, recovery that takes longer than it used to, or tissue damage that's limiting your movement and quality of life — your body has the machinery to heal. Sometimes it just needs a stronger signal. TB-500 provides exactly that: a targeted peptide that amplifies your body's own repair mechanisms, helping you get back to the life you're working so hard to live.

What Is TB-500?

TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring 43-amino acid peptide found in nearly every human cell. Your body already produces it — it plays a central role in tissue repair, cell migration, and the formation of new blood vessels. The therapeutic form amplifies these signals, giving your body a clearer, stronger directive to heal.

Where TB-500 stands apart is its mechanism: it upregulates actin, a cell-building protein that’s essential for cell movement and tissue reconstruction. When tissue is damaged, cells need to migrate to the injury site and rebuild. TB-500 accelerates that entire process — promoting the movement of repair cells, reducing inflammation, and supporting the formation of new blood vessels to nourish healing tissue.

Who Is This For?

TB-500 is particularly relevant if you’re dealing with:

  • Slow-healing soft tissue injuries — tendons, ligaments, and muscle strains that linger
  • Post-surgical recovery — supporting your body’s repair timeline after a procedure
  • Chronic inflammation — persistent low-grade inflammation that impairs healing
  • Age-related recovery decline — when your body’s natural repair mechanisms have slowed

This isn’t a shortcut around the healing process. It’s a way to ensure your biology is running that process at full capacity — with a provider-directed protocol monitoring every step.

Zvia’s Approach to Tissue Repair and Recovery Peptides

At Zvia Weight Loss & MedSpa in Lakewood, Colorado, no recovery protocol is ever built in isolation. Your provider starts with a comprehensive picture — labs, history, current condition — before any plan takes shape, with dosing, timing, and delivery calibrated to you rather than pulled from a standard formula, and progress tracked through regular check-ins so the plan can adapt as your body responds. That’s the same rigor we’d bring to TB-500 the moment it’s available to offer, and it’s the standard we hold across every peptide in the tissue repair and recovery category today.

The full deep-dive on TB-500 — including mechanism of action, clinical evidence, and what to expect — is coming soon. In the meantime, if you’re curious about how provider-directed recovery protocols work, your Zvia care team is ready to talk it through with you.

FAQ

Common questions about TB-500

Is TB-500 safe?
TB-500 is a synthetic version of Thymosin Beta-4, a peptide naturally found in nearly every human cell. A provider-directed protocol would evaluate your full health picture before prescribing and include monitoring throughout to help ensure safety.
How long does TB-500 take to work?
Based on published research, most people can expect to notice improvements in recovery and inflammation within two to four weeks, though results vary depending on the nature and severity of the condition being treated. A provider-directed protocol would track progress and adjust as needed.
What are the side effects of TB-500?
Reported side effects are generally mild and uncommon — some individuals may experience temporary redness at the injection site or brief lightheadedness. A provider-directed protocol would include monitoring for any concerns and adjusting accordingly.
How is TB-500 administered?
TB-500 is typically administered via subcutaneous injection. Your provider determines the optimal dosing schedule and injection sites based on your specific condition and therapeutic goals.
Who is a good candidate for TB-500?
TB-500 may be a good fit for individuals dealing with slow-healing soft tissue injuries, post-surgical recovery, chronic inflammation, or age-related decline in recovery capacity. Your Zvia provider would assess your labs, history, and goals to determine if TB-500 is appropriate for your situation.
