- TB-500 Peptide
- Promotes angiogenesis, actin-mediated cell migration, and ECM remodelling
- 4–12 weeks with consistent dosing
- 60–70% pain reduction in case series (no RCTs)
- Most promising for chronic cases resistant to conservative care—requires consistent subcutaneous administration and concurrent eccentric loading exercises
- Corticosteroid Injection
- Suppresses inflammation via glucocorticoid receptor binding
- Immediate (48–72 hours)
- 70–80% short-term relief; 40–50% at 6 months
- Fast symptom relief but associated with fascia weakening and rupture risk—degrades collagen structure over time
- Platelet-Rich Plasma (PRP)
- Delivers growth factors (PDGF, TGF-β, VEGF) from concentrated autologous platelets
- 6–12 weeks
- 65–75% at 6 months in meta-analyses
- Evidence stronger than TB-500 currently; requires proper preparation protocol (leukocyte-poor PRP preferred for tendinopathy)
- Eccentric Stretching Protocol
- Mechanically loads fascia to promote collagen realignment and tensile strength
- 8–12 weeks of daily execution
- 60–70% improvement in systematic reviews
- Gold standard conservative treatment—most effective when combined with load management and footwear modification
- Extracorporeal Shockwave Therapy (ESWT)
- Delivers acoustic waves to induce microtrauma, neovascularisation, and pain modulation
- 3–6 sessions over 3–6 weeks
- 60–65% at 3 months; 70–80% at 12 months
- Best evidence for recalcitrant cases—works by resetting chronic inflammation and stimulating repair signaling
- The table underscores a critical point: TB-500 addresses tissue repair mechanisms similar to PRP but without requiring blood draws or centrifugation. However, PRP has Level 1 clinical evidence from multiple RCTs, while TB-500 remains in the realm of experimental use. Corticosteroid injections provide the fastest symptom relief but carry documented risks of fascia rupture—a 2018 meta-analysis in Foot & Ankle International reported rupture rates of 2.4% following steroid injection versus 0.1% in conservative treatment groups.
- Eccentric stretching remains the foundation of any plantar fasciitis protocol. The Achilles-plantar fascia complex functions as a continuous kinetic chain—loading the Achilles through controlled eccentric lowering (heel drops off a step) transmits tensile forces through the fascia, promoting collagen realignment. TB-500 may accelerate this process by improving vascular supply to the damaged tissue, but it doesn't replace mechanical loading.
