What TB-500 Is Used For
TB-500 (also written TB500 or TB 500) is used for recovery, flexibility and soft-tissue support. Patients choose it after a muscle, tendon or ligament injury, during a heavy training block, or when a joint has stayed stiff longer than expected.
Typical patients are active adults and people rehabbing an injury who want recovery to move faster. Your provider confirms TB-500 fits your goal and sets the protocol.
TB-500 Benefits
TB-500's benefits are organized around three goals. Research is mostly in animal models; the points below are what patients commonly report and what that research supports.
- Soft-tissue recovery. Research supports faster repair of muscle, tendon and ligament tissue. Patients commonly report quicker bounce-back between sessions.
- Flexibility and mobility. TB-500 is associated with reduced stiffness and improved range of motion in recovering joints.
- Inflammation. Research supports lower inflammatory markers at injury sites, which is part of why recovery feels smoother.
Peptide therapy in general, including sermorelin, is prescribed off-label by a licensed provider. No outcome is guaranteed.
TB-500 vs BPC-157
The two most-searched recovery peptides work through different mechanisms, which is why providers often pair them rather than pick one. TB-500 binds actin and helps repair cells migrate into injured tissue, so it suits systemic soft-tissue recovery, flexibility and mobility across more than one area. BPC-157 works through growth-factor and blood-flow signaling and is the pick for a specific tendon or ligament and for gut health.
As a rule of thumb: a provider leans toward BPC-157 for a localized tendon repair, TB-500 for whole-body recovery after hard training or multiple nagging injuries, and both as separate prescriptions when the goal covers both.
How TB-500 Works
TB-500 is a synthetic seven-amino-acid fragment of thymosin beta-4, a protein found in nearly every human cell. It carries the section of thymosin beta-4 that binds actin, the structural protein cells use to move. That lets repair cells migrate into injured tissue faster and supports new blood-vessel growth around it, the two mechanisms research describes for its recovery effects.
How TB-500 Is Prescribed
Form prescribed (TB-500 acetate)
- Subcutaneous injection
Your provider sets strength and schedule and adjusts at follow-up. TB-500 is prescribed on its own; for a recovery stack, your provider can write a separate prescription for BPC-157.
TB-500 Cost
TB-500 is $299.99 for two vials, up to a 10-week supply depending on the dose your provider sets. The two vials can be the same peptide or one vial each of two different peptides. The price includes the provider consult, prescription review and cold-chain shipping. No insurance needed, HSA and FSA accepted, cancel anytime.
TB-500 · Injectable
$299.99

TB-500 Side Effects
TB-500 is well tolerated. Reports are limited to mild injection-site redness, occasional headache and a short period of tiredness after injection. Tell your provider about anything persistent.
Your provider will not prescribe TB-500 if you have
- Active cancer or a history of malignancy, because TB-500 supports blood-vessel growth
- Pregnancy or breastfeeding
- Under 18
- Athletes in tested sport: TB-500 is on the WADA prohibited list
Compounded TB-500: What to Know
- Available by prescription
- Compounded by a 503A pharmacy
- Not an FDA-approved product
- HHS policy, Oct 28, 2026
TB-500 is available by prescription under the October 2026 HHS enforcement discretion policy, compounded as an injection by a licensed 503A pharmacy. It is a compounded medication, not an FDA-approved product. TB-500 is on the World Anti-Doping Agency prohibited list, so athletes in tested sport should not use it.

TB-500 FAQ
It depends on the goal. TB-500 for whole-body soft-tissue recovery and mobility, BPC-157 for a specific tendon, ligament or gut issue, and often both as separate prescriptions. See the TB-500 vs BPC-157 comparison above.
Your provider sets the weekly amount and schedule based on your goal and history, as a subcutaneous injection, and adjusts it at follow-up.
Some patients report thicker hair, and thymosin beta-4 has been studied for hair-follicle activity in animal models. It is not what TB-500 is prescribed for, and results in people have not been established.
For a specific tendon, providers usually lean toward BPC-157, which has the larger body of tendon research. TB-500 is added when recovery is broader than one site.
Yes, as separate prescriptions when your provider recommends it. It is the most common recovery pairing in the program.
TB-500 is prohibited by WADA at all times, so athletes in tested sport should not use it. For everyone else it is available by prescription.
Yes, by prescription through a licensed 503A pharmacy under the October 2026 HHS policy. Research-grade vials sold online are not covered.
