TB-500

TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide involved in tissue repair and cell migration. It promotes healing, reduces inflammation, and can improve flexibility and range of motion after injuries.

The typical protocol is 2 to 5 mg injected subcutaneously, usually twice a week during a loading phase, then dropping to a maintenance dose. It's commonly used for muscle tears, tendinitis, and joint injuries.

TB-500 works through a different mechanism than BPC-157, which is why they're frequently combined. BPC-157 promotes angiogenesis (new blood vessel formation) while TB-500 focuses on cell migration and differentiation.

TB-500 tends to be slower than BPC-157. Most people start noticing reduced stiffness and improved mobility around weeks 2 to 4. A typical loading phase runs 4 to 6 weeks with twice-weekly injections, then maintenance at once weekly or less.

For acute injuries, the response is usually faster. For chronic issues like long-standing tendinitis, give it the full loading phase before judging whether it's working.

Generally well tolerated. The most common report is a temporary head rush or slight lethargy after injection. Some people get mild headaches. Injection site redness or irritation can happen.

Like BPC-157, there's a theoretical angiogenesis concern. The original Thymosin Beta-4 research flagged potential interactions with certain cancers, though this hasn't been definitively established with TB-500. Worth discussing with your provider if you have a relevant history.

Refrigerate after reconstitution at 36 to 46°F. Powder form can be stored at room temperature. Once reconstituted with bacteriostatic water, use within 28 days.

TB-500 doses are larger than most peptides (milligrams rather than micrograms), so you'll go through vials faster. Plan your water volume accordingly so you're not drawing huge volumes per injection.
