- TB-4 is a naturally occurring peptide that supports cell migration, controls inflammation, and promotes angiogenesis (new blood vessel growth). TB-500 is a smaller, synthetic fragment engineered for deeper tissue penetration, but it lacks several biological functions of the full TB-4 molecule.
- Injuries often stall due to poor blood flow, chronic inflammation, overuse, scar tissue buildup, and nutritional deficiencies. Understanding why your body isn't healing is the critical first step—before considering experimental peptides like TB-4 or TB-500.
- Because stalled healing can stem from many overlapping causes, guessing wrong can waste time and money—or worse, delay treatment for a serious underlying condition. A free, instant, online symptom check built by physicians can help you identify likely causes based on your specific symptoms and guide your next steps with confidence.
