TB-500
Also known as: Thymosin Beta-4, TB4
Systemic Healing Power
Often stacked with BPC-157 for comprehensive healing. TB-500 provides systemic tissue repair throughout the body.
How It Works
Simple Explanation
Promotes cell migration and blood vessel formation for widespread tissue repair.
Technical Details
Active fragment of Thymosin Beta-4. Upregulates actin for cell building, migration, and new blood vessel growth.
Pharmacokinetics & Storage
Half-Life
~2-3 hours in circulation, but effects persist due to tissue distribution
Duration in circulation
Storage Requirements
Reconstitute with bacteriostatic water. More fragile than BPC-157 - handle carefully to avoid degradation.
Research Timeline: What Studies Have Observed
Based on clinical trial data and published research. Individual responses may vary significantly.
Weeks 1-2 (Loading)
Research protocols used higher initial doses. Studies observed early anti-inflammatory effects and increased cellular mobility.
Weeks 3-4 (Loading)
Animal studies documented accelerated wound healing and tissue repair. Increased blood vessel formation noted in research.
Weeks 5-6 (Transition)
Studies showed continued healing benefits. Research protocols typically transitioned to maintenance dosing.
Maintenance Phase
Research suggests periodic dosing maintains tissue repair support. Some protocols used monthly boosters for ongoing benefits.
Benefits
- Systemic healing effects
- Reduced inflammation
- Improved flexibility
- Heart tissue protection
- Hair regrowth potential
Potential Side Effects

Known Interactions
Based on clinical research and pharmacological studies. Always consult a healthcare provider about potential interactions.
Anti-cancer Drugs
avoidTheoretical concern that pro-angiogenic effects could interfere with anti-cancer treatments. Research advises avoidance.
Immunosuppressants
monitorTB-500 may modulate immune function. Research suggests monitoring if combined with immunomodulating drugs.
BPC-157
monitorOften combined in research protocols with reportedly synergistic effects. No negative interactions documented.

How It Compares
Research-based comparisons with similar peptides. Individual responses and circumstances should guide decisions.
BPC-157 offers more localized, targeted healing with potentially better stability. Research suggests choosing based on injury type - localized vs. systemic issues.
GHK-Cu provides anti-aging and skin-focused benefits. TB-500 may be preferred for deeper tissue and musculoskeletal healing.
