TB-500 50s Age Protocol: Peptide Comparison
TB-500 (Thymosin Beta-4) Actin-binding, angiogenesis, cell migration 2.5–5mg 2×/week loading 1.5–2mg every 72–96h loading Daily BP first 4 weeks, weekly weight Effective for tendon/ligament repair in 50+ if dosed conservatively; higher side effect risk than BP
This comparison does not assign a generated winner or score.
- TB-500 (Thymosin Beta-4)
- Actin-binding, angiogenesis, cell migration
- 2.5–5mg 2×/week loading
- 1.5–2mg every 72–96h loading
- Daily BP first 4 weeks, weekly weight
- Effective for tendon/ligament repair in 50+ if dosed conservatively; higher side effect risk than BPC-157 due to systemic angiogenic effects
- BPC-157
- Gastric mucosa-derived, VEGF modulation, NO pathway
- 250–500mcg daily
- 250mcg daily (no reduction needed)
- Minimal. Spot-check BP weekly
- Generally better tolerated in 50+ populations; more localised action, less systemic vascular impact; slower subjective improvement timeline
- GHK-Cu
- Copper peptide, collagen synthesis, anti-inflammatory
- 1–2mg 3×/week
- 1mg 3×/week
- None required for most users
- Minimal cardiovascular interaction; primarily dermal and subcutaneous effects; slower onset but excellent safety profile for 50+
- Thymalin
- Thymus-derived, immune modulation
- 5–10mg 2×/week
- 5mg 2×/week (monitor immune markers)
- None for CV; immune panel at weeks 4 and 8
- Immune system stimulation may interact with autoimmune conditions more common in 50+; requires baseline immune function assessment
