- TB-4 (Thymosin Beta-4)
- Actin-binding protein. Promotes cell migration, angiogenesis, reduces inflammation
- 2.5–5mg/mL
- Bacteriostatic water pH 5.5–6.5
- 28 days maximum
- Gold standard for tissue repair and regenerative models. Fragile structure requires careful handling but unmatched efficacy in wound healing studies
- BPC-157
- Gastric pentadecapeptide. Angiogenic, protects endothelium, modulates growth factor expression
- 0.5–1mg/mL
- Bacteriostatic water or saline (less pH-sensitive)
- 60 days if stored correctly
- More stable than TB-4 post-reconstitution but narrower mechanism. Best for GI and tendon models rather than systemic regeneration
- GHK-Cu (Copper Peptide)
- Copper-binding tripeptide. Collagen synthesis, antioxidant, metalloproteinase modulation
- 1–2mg/mL
- Bacteriostatic water (copper complexation requires controlled pH)
- 14–21 days (copper oxidation limits shelf life)
- High efficacy in dermal models but shortest post-mix stability. Requires fresh reconstitution every 2–3 weeks for reliable results
- The comparison underscores why TB-4 research strength considerations demand more rigorous protocols than more stable peptides like BPC-157. The 28-day post-reconstitution window isn't conservative. It's the outer limit before degradation becomes statistically significant.
