TB-500 (Thymosin Beta-4) Standalone Protocol [2026]
Systemic tissue repair research using TB-500 actin-sequestering mechanism for injury recovery and cellular migration.
Compounds
TB-500
Dose: 2.5 mg
Freq: Twice weekly loading, then once weekly
Recon: 5mg + 2mL BAC
Conc: 2.5 mg/mL
Draw: 100 units (U-100)
Calculate TB-500 dose
Protocol Phases
Loading Phase
Weeks 1 to 4
2.5 mg SubQ twice weekly. Total 5 mg per week during loading. Systemic injection in abdomen is standard. TB-500 works systemically and does not need to be injected near the injury site.
Maintenance Phase
Weeks 5 to 12
2.5 mg SubQ once weekly. Some protocols use 5 mg once weekly throughout for acute injury recovery.
FAQ
Does TB-500 need to be injected near the injury site?
No. TB-500 works systemically through actin regulation and cell migration signaling. It can be injected subcutaneously in any convenient location, most commonly the abdomen. The systemic distribution means it reaches injured tissue regardless of injection site.
How long does TB-500 take to show effects?
Many research subjects report noticeable effects on recovery speed and injury pain within 2 to 3 weeks of loading doses. More significant structural repair typically requires a full 4 to 8 week loading phase for assessment.
What is the difference between TB-500 and BPC-157 for injury recovery?
BPC-157 primarily drives repair through growth factor upregulation and nitric oxide at specific injury sites. TB-500 promotes cell migration (particularly satellite cells, macrophages, and endothelial cells) throughout the body. TB-500 produces more systemic anti-inflammatory and repair signaling. They are commonly stacked because their mechanisms are complementary rather than redundant.
Research Notes
- TB-500 produces systemic effects. No need to inject near the injury.
- Reconstitute with bacteriostatic water. 5 mg vial in 2 mL BAC water gives 2.5 mg/mL.
- Some research subjects notice mild fatigue in the first week. This is transient.
