- Acute injuries. Muscle strains, ligament sprains, surgical incisions. Respond to aggressive front-loading: 5–10mg twice weekly for two weeks, then 5mg weekly for four weeks. Chronic injuries. Tendinopathy, non-healing ulcers, scar tissue remodeling. Require sustained low-dose exposure: 2.5–5mg once or twice weekly for 8–12 weeks. The distinction isn't arbitrary. Acute injuries involve active inflammation and robust cellular turnover; chronic injuries involve fibrosis, reduced vascularity, and senescent cell populations that respond slowly to regenerative signals.
- For chronic tendon injuries, protocols often extend to 12–16 weeks at 2.5–5mg weekly because collagen remodeling operates on a much slower timeline than acute soft tissue repair. TB-4 stimulates matrix metalloproteinases (MMPs) that break down disorganized scar tissue while promoting organized collagen deposition. But this remodeling process takes months, not weeks. Stopping at week 6 leaves the tendon structurally improved but incompletely remodeled.
- In our experience working with researchers in this space, the biggest dosing error is abandoning the protocol too early. Acute injuries show visible improvement within 10–14 days, which tempts users to stop. Chronic injuries show minimal subjective change for the first 4–6 weeks, leading to the same premature discontinuation. The peptide's regenerative effects compound over time. Cutting the protocol short at week 4 instead of week 8 can mean the difference between partial recovery and full structural repair.
