- The following table compares ipamorelin stability across the most common storage conditions researchers encounter. The 'Degradation Rate' column reflects peptide bond cleavage and aggregation measured as percentage potency loss per month. The 'Use Timeline' column represents the maximum duration before potency drops below 90% of original concentration.
- Lyophilised, frozen
- −20°C
- <0.1% per month
- 24–36 months
- Gold standard for long-term storage of unreconstituted ipamorelin. Minimal thermal or oxidative degradation
- Lyophilised, refrigerated
- 2–8°C
- 1–2% per month
- 6–9 months
- Suboptimal but viable short-term. Use only if freezer unavailable and vial will be reconstituted within 90 days
- Lyophilised, room temp
- 20–25°C
- 3–5% per month
- 2–3 months
- High degradation risk. Acceptable only during brief shipping periods with cold packs, not for storage
- Reconstituted, refrigerated
- 3–4% per month
- 28 days
- Correct storage post-reconstitution. Aggregation accelerates beyond 30 days even with bacteriostatic water
- Reconstituted, room temp
- 150–240% per month
- 48–72 hours
- Rapid denaturation. Peptide bonds cleave and aggregates form within hours, not days
- Reconstituted, frozen
- Immediate upon thawing
- Not recommended
- Ice crystal formation physically disrupts peptide structure. Freezing reconstituted peptides causes irreversible aggregation
