What Is TB-500?
Thymosin beta-4 is a naturally occurring protein involved in how cells move and organize, especially where tissue is under repair. TB-500 is a synthetic peptide modeled on the active region of that protein. The form prescribed at Evolve Health is TB-500 acetate.
What Researchers Are Studying
Research on TB-500 is still early and comes mostly from laboratory and animal work. Areas of interest include:
- Supporting the body's natural tissue-recovery processes after strain or training
- Flexibility and mobility
- Recovery and return to activity as part of a broader plan
Active adults, weekend athletes, people who train hard, and anyone frustrated by slow recovery, are the patients who ask us about TB-500 most often.
How It's Prescribed at Evolve Health
TB-500 acetate is prescribed as a subcutaneous or intramuscular injection. It is always prescribed as a single-ingredient formulation and is never combined with another peptide.
Prescriptions are written for one patient and filled by a LegitScript-certified 503A compounding pharmacy using ingredients from FDA-registered facilities with a certificate of analysis.
Is TB-500 Right for You?
Your provider decides that with you during a comprehensive consultation that covers your health history, medications, activity level, goals, and labs. TB-500 may not be appropriate during pregnancy or breastfeeding, or with an active cancer or one under evaluation.
What to Expect
After your consultation and labs, your provider builds a plan, shows you how to administer your medication, and schedules an early check-in. Follow-up visits track how you're feeling and whether the plan should change.
