- Lyophilized powder (unreconstituted)
- −20°C (freezer)
- 24–36 months
- Low (minimal degradation in solid form)
- Moderate (avoid repeated cycles)
- Best for long-term storage. Most stable form with longest shelf life when kept frozen
- Reconstituted with bacteriostatic water
- 2–8°C (refrigerator)
- 28 days
- High (photochemical oxidation accelerates in solution)
- None (never refreeze reconstituted peptide)
- Use within 28 days. Potency drops measurably after 3–4 weeks even with proper refrigeration
- Room temperature (lyophilized)
- 20–25°C
- 6–12 months
- Moderate
- Low
- Acceptable for short-term pre-reconstitution storage but degrades 60–70% faster than frozen
- Room temperature (reconstituted)
- 24–48 hours
- Very high
- None
- Potency loss begins within hours. Only viable for same-day transport between refrigerators
