TB-500 for Ligament Tear: Dosing & Timeline Comparison

This comparison does not assign a generated winner or score.
- Acute Inflammation
- Days 0–7
- Peak swelling, pain, limited mobility
- Reduced inflammatory duration by 2–3 days via M2 macrophage shift
- TB-500 accelerates transition from inflammatory to proliferative phase
- Modest benefit. Inflammation reduction is measurable but not dramatic
- Fibroblast Infiltration
- Days 3–14
- Random cell migration, disorganized matrix
- Enhanced directional migration, 47% higher collagen density (animal data)
- Actin polymerization guides fibroblast movement toward injury centre
- Strongest evidence window. This is where TB-500 shows clearest benefit
- Collagen Deposition
- Days 14–42
- Type III collagen predominates, 40–60% tensile strength
- More organized type I/III ratio, 70–85% strength potential
- VEGF upregulation supports vascularization during remodeling
- Promising but highly dependent on mechanical loading and rehab protocol
- Remodeling Phase
- Months 2–12
- Gradual type III to type I conversion, risk of re-tear if loaded too early
- Potentially faster remodeling if vascular supply was established early
- Mature collagen cross-linking continues long after peptide clears
- TB-500 effect here is indirect. Early vascular gains may support later remodeling
- Return to Activity
- Months 3–6
- 50–70% return to pre-injury function typical
- Anecdotal reports suggest 10–20% faster return, lower re-injury rates
- Not TB-500 alone. Combined effect with structured rehab
- No controlled human data. Promising signals but not definitive
- This table reflects animal model data and extrapolated human dosing. Human ligament tears (ACL, MCL, ankle ligaments) have longer total healing timelines than rat Achilles tendons. The percentages shown are conservative estimates based on mechanistic plausibility.
