What Is TB-500?
TB-500 is commonly described as a synthetic fragment related to thymosin beta-4, a naturally occurring peptide involved in actin binding, cell migration, angiogenesis, and tissue-repair signaling. It is not FDA-approved for human therapeutic use.
How It Works
TB-500-related claims are often based on thymosin beta-4 biology and preclinical wound-healing/tissue-repair research. TB-500 should not be presented as equivalent to all thymosin beta-4 clinical research; claims remain cautious and its mechanism is not an established human clinical effect.
What It’s Studied For
Thymosin beta-4 has published research in wound healing, tissue repair, angiogenesis, inflammation resolution, and dermal healing; TB-500 itself has limited human data, and current orthopedic and wellness claims are often extrapolated from preclinical or related-peptide studies. It is not FDA-approved for these uses.
Regulatory Status
TB-500-related substances have been part of FDA compounding-safety discussions (immunogenicity and peptide-impurity concerns), and TB-500 is prohibited for athletes under the WADA framework. Compounding availability is subject to that status.
What to Expect
Use is provider-directed only; no outcome or timeline is promised, and it does not replace standard care for injury.
Preferred Starting Options / Dosing Notes
Many patients begin with a lower starting option so a licensed clinician can evaluate tolerance, medical history, goals, and safety factors before any adjustments are considered. The starting option shown below is informational and reflects available program data, not self-directed dosing instructions. Final medication, dose, frequency, and treatment plan are determined by a licensed clinician.
Average starting option
- 10 mg
Available options
- 10 mg
Provider note: Do not change dose, frequency, or route of use unless directed by your clinician.
Safety Considerations
- Human exposure data are limited and long-term risk unknown.
- Possible concerns include injection-site and immune reactions and sterility/purity issues.
- No peptide is "safe" without qualification.
Important note
Some treatments may involve compounded medications when prescribed by a clinician. Compounded medications are not FDA-approved. The FDA does not evaluate compounded medications for safety, effectiveness, or quality before marketing.
Who Is Not a Candidate
A clinician reviews injury history, recovery goals, medications, immune status, pregnancy status, and cancer history, and whether standard care has been addressed, before considering TB-500.
How It Compares
Both are marketed for recovery but are different molecules with different proposed mechanisms; both are preclinical-evidence-dominant and not FDA-approved.
Frequently Asked Questions
Is TB-500 FDA-approved or WADA-banned?
Not FDA-approved for human therapeutic use, and prohibited for athletes under WADA.
How does it work?
Claims are based largely on thymosin beta-4 biology; TB-500's own human evidence is limited.
What is TB-500 used for?
It is discussed for recovery/tissue repair, but human clinical evidence is limited.
TB-500 vs BPC-157?
Different molecules and mechanisms; both preclinical-dominant and not FDA-approved.
Does payment guarantee a prescription?
No — a licensed clinician decides.
