The TB-500 guideUnderstand. Check. Ask. Bring your questions

Get oriented

Begin with the problem that needs care

Turn a search for an injection into a clear question about care.

In the US, medicines are reviewed by the Food and Drug Administration, known as the FDA.

Put your goal into words

  • What is bothering you? Use your own words.
  • When did it begin, and what makes it better or worse?
  • What have you tried, and what happened?
  • What matters most: daily comfort, movement, work, or sport?

A short note can give a visit a useful starting point. Describe the change you want, without choosing a treatment first.

Prepare for the conversation

Bring a small set of notes

Keep the visit focused. A page of notes is enough to hold your questions.

  • List your medicines and supplements as they appear on their labels.
  • Bring any records you already have.
  • Mark the claim you want a doctor or another licensed health professional to explain.
  • Leave room to write down options and next steps.

Keep a search result in perspective

A product page can make a claim sound settled. The evidence may tell a different story.

  • The FDA recorded online claims about TB-500 for injury repair, muscle growth, and other goals, but found no human study supporting those uses.
  • As of September 2026, TB-500 is not an FDA-approved treatment for an injury or any other condition in the United States.
  • Ask about the cause of the problem before asking for a named injection.
