Your TB-500 is compounded by a state-licensed U.S. pharmacy and prescribed only after a licensed clinician reviews your intake, health history and medications. Research-chemical vials have none of that oversight. Compounded medications are not FDA-approved.
A typical protocol is once daily, 5 days on and 2 days off, for 3 months, followed by 1 month off. Your clinician sets your exact directions.
Some people pair the two because they have been studied for tissue repair through different pathways. Tell your clinician during the intake; they decide what's right for you.
TB-500 is a subcutaneous injection with a very small needle. Users typically describe it as a brief pinch, similar to a small insulin injection.
Individual response varies, and most research on TB-500 is preclinical, so we can't promise a timeline or a result. Your care team checks in during your plan and your clinician can adjust it.
Mild injection-site reactions such as redness or irritation are possible. Your clinician reviews known and potential risks with you during the intake before prescribing.
Keep your vial refrigerated between 36°F and 46°F. Store it in its original packaging, protected from heat and light. If you notice changes in color or clarity, contact the clinical team.
Your vial ships cold-packed on your refill schedule. You can pause or cancel anytime from your dashboard. TB-500 can't be shipped to California or South Carolina.
