PT-141 Storage Methods: Lyophilised vs Reconstituted Comparison
Lyophilised (powder) −20°C to −80°C 24–36 months Minimal. Peptide bonds stable in dry state High. Multiple cycles acceptable None. Sealed sterile vial Reconstituted (bacteriostatic water) 2–8°C (refrigerated) 28 days Thermal denaturation + oxidation Zero. Sing

- Lyophilised (powder)
- −20°C to −80°C
- 24–36 months
- Minimal. Peptide bonds stable in dry state
- High. Multiple cycles acceptable
- None. Sealed sterile vial
- Reconstituted (bacteriostatic water)
- 2–8°C (refrigerated)
- 28 days
- Thermal denaturation + oxidation
- Zero. Single freeze destroys bioactivity
- Low. Benzyl alcohol suppresses bacteria
- Reconstituted (sterile saline)
- 7–10 days
- High. No antimicrobial preservative
- Room temperature (reconstituted)
- 20–25°C
- 24–72 hours before significant loss
- Accelerated thermal denaturation
- N/A. Already degrading
- High. Bacterial growth accelerates
- Frozen (reconstituted)
- −20°C or below
- Not recommended. Immediate potency loss
- Ice crystal shear stress on peptide structure
- Destructive. 60–85% activity loss per cycle
- N/A. Peptide is already inactive
