Questions about TB-500

Why would I take it?

Your body repairs itself more slowly as you get older. Fewer repair cells arrive, and they arrive later. That is why strains linger longer than they used to and old injuries keep flaring. TB-500 is taken to get repair cells moving again, alongside the rest and rehab that do the heavy lifting.

What is the history?

Thymosin beta-4 was first found in the thymus gland, which gave it its name. It has been studied for decades for wound, eye and heart repair. The full protein has been tested in human trials as eye drops and as a skin gel. TB-500 itself, the lab-made fragment, has been studied in animals only. It is prescribed off-label and compounded for you.

How do I monitor it, and what happens when I stop?

No routine blood work is needed for TB-500 itself; your clinician reviews how you respond. When you stop, nothing rebounds, and your own thymosin beta-4 keeps working as before.

How is it different from BPC-157?

BPC-157 is best known for growing new blood vessels into an injury. TB-500 is best known for moving repair cells to it. Some men take both, as two separate prescriptions.

Can I go on and off it?

Yes. TB-500 is taken in cycles: a cycle while you recover, a pause, then another cycle if an injury flares. Your clinician sets the length of each.

How soon will I notice a difference?

It depends on the injury. Muscle responds sooner than tendon, so give a cycle several weeks before you judge it.

Important safety information

TB-500 is a compounded medication. Compounded drugs are permitted to be prescribed under federal law, but are not FDA-approved and do not undergo FDA safety, effectiveness, or manufacturing review. Prescriptions are issued only if a licensed clinician finds treatment appropriate. Use only the dose and schedule your clinician sets. Common side effects include redness or soreness at the injection site, headache, tiredness and a brief light-headed feeling after the injection. Do not use if you have or have had cancer, since TB-500 encourages new blood vessel growth and cell movement, or if you are pregnant or breastfeeding. TB-500 is prohibited in tested sport under the World Anti-Doping Code. Tell your clinician about all medications and supplements you take. Store as your pharmacy label says. This is not a complete list; your clinician will review risks with you.
