Tissue Repair / RecoveryEvidence Grade: B (Animal + Preclinical)
TB-500 Protocol Guide
TB-500 is a synthetic version of the naturally occurring peptide thymosin beta-4, a 43-amino acid protein found in virtually all human and animal cells. It is researched for its ability to promote systemic tissue repair, reduce inflammation, enhance flexibility, and support cardiac tissue recovery. Unlike BPC-157 which works locally, TB-500 acts systemically by upregulating actin and promoting cell migration throughout the body.
Protocol Overview
- Compound
- TB-500 (Thymosin Beta-4 Fragment)
- Category
- Tissue Repair / Anti-inflammatory
- Mechanism
- Upregulates actin protein for cell building, migration, and proliferation. Promotes angiogenesis, reduces inflammation via TNF-alpha modulation, and supports stem cell differentiation
- Molecular Weight
- 4,963 Da
- Half-Life
- ~2-3 days
- Vial Size
- 10mg lyophilized powder
- Route
- Subcutaneous or intramuscular
- Frequency
- 2-3x per week
- Cycle Length
- 8-12 weeks (loading + maintenance)
Dosing Protocol
| Phase | Weeks | Dose/Week | Schedule | Route |
|---|---|---|---|---|
| Loading Phase | 1-4 | 5-10 mg/week | 2.5mg 2-3x/week | Subcutaneous |
| Maintenance | 5-12 | 2-5 mg/week | 2.5mg 1-2x/week | Subcutaneous |
Loading rationale: The loading phase saturates tissues with TB-500 to initiate repair cascades. After 4 weeks, the maintenance dose sustains these processes while reducing total peptide usage.
Reconstitution Instructions
Materials Needed
- TB-500 10mg lyophilized vial
- Bacteriostatic water
- 3mL syringe (18-20ga) for mixing
- Insulin syringes (29-31ga) for dosing
- Alcohol swabs
Steps
- Clean vial stopper with alcohol
- Draw 2mL bacteriostatic water
- Inject slowly down vial wall
- Gently swirl until dissolved
- Concentration: 5 mg/mL
- 2.5mg = 0.5mL = 50 units on insulin syringe
Administration Guide
Injection Sites
- Abdomen: Most common (TB-500 is systemic)
- Thigh: Front/outer mid-thigh
- Location does NOT need to be near injury
- Rotate sites between injections
Timing & Storage
- Timing: Any time of day, consistent schedule
- Schedule: Mon/Wed/Fri or Mon/Thu for 2x/week
- Storage: Refrigerate 2-8°C after reconstitution
- Shelf life: Use within 30 days of reconstitution
Expected Timeline
Week 1-2
Initial loading phase. Subtle reduction in inflammation and stiffness. Some subjects report improved flexibility and reduced pain within the first week.
Week 3-4
Significant anti-inflammatory effects. Enhanced blood flow to injured areas. Noticeable improvements in range of motion and soft tissue flexibility.
Week 5-8
Peak healing effects during transition to maintenance. Tendon, ligament, and muscle repair progressing. Hair and skin quality improvements reported by some subjects.
Week 9-12
Continued tissue remodeling and strengthening. Chronic injuries show significant improvement. Maintenance dose sustains repair processes.
Side Effects & Monitoring
Common Side Effects
- Injection site irritation (mild, temporary)
- Head rush or lightheadedness post-injection
- Mild lethargy (usually first week)
- Temporary flu-like symptoms (rare)
Precautions
- Avoid with active cancer (angiogenesis concern)
- Not recommended during pregnancy
- May interact with anticoagulants
- Discontinue if persistent adverse effects
Stacking Recommendations
Compatible Compounds
- BPC-157: #1 stack - systemic (TB-500) + local (BPC-157) healing
- GHK-Cu: Collagen and tissue remodeling
- Ipamorelin: GH release for recovery support
- Sermorelin: Additional GH axis support
Classic Healing Stack
- TB-500: 2.5mg 2x/week (subQ abdomen)
- BPC-157: 250mcg 2x/day (subQ near injury)
- Duration: 6-8 weeks
- This is the most researched healing peptide combination
Blood Work Recommendations
| Panel | Markers | Timing |
|---|---|---|
| Basic | CBC, CMP | Baseline, Week 6 |
| Inflammatory | CRP, ESR, TNF-alpha | Baseline, Week 4, 8 |
| Liver | ALT, AST | Baseline, Week 6 |
