  • BPC-157
  • −20°C, 18–24 months
  • 2–8°C, 28 days
  • Moderate. Up to 2 cycles tolerated
  • Cloudiness, visible particulate
  • Most stable component in the stack. Tolerates minor storage errors better than TB-500
  • TB-500 (Thymosin Beta-4)
  • −20°C, 12–18 months
  • 2–8°C, 21 days
  • Low. Single freeze-thaw maximum
  • Loss of clarity, slight yellowing
  • Highly sensitive to oxidation. Store in amber vials if possible and use within 3 weeks of reconstitution
  • GHRP-2
  • Cloudiness, pH shift
  • Requires strict adherence to 2–8°C range. Temperature excursions above 10°C cause rapid degradation
  • Bacteriostatic Water
  • Room temp, 2 years sealed
  • 2–8°C, 28 days after opening
  • N/A
  • Cloudiness, bacterial growth
  • The preservative degrades faster than the peptides. Replace every 28 days regardless of peptide stability
