- The table below compares storage conditions, degradation timelines, and practical use windows for GHRP-2 acetate in lyophilised versus reconstituted form. Understanding these differences is critical for maintaining research consistency. A peptide stored incorrectly for even 48 hours can lose enough potency to invalidate dose-response data.
- Lyophilised, sealed, inert atmosphere
- −20°C to −80°C
- <1% degradation per year
- 24–36 months
- Gold standard for long-term storage; degradation effectively arrested. Open only when ready to reconstitute.
- Lyophilised, ambient (unopened)
- 20–25°C
- 3–5% degradation per month
- 6–9 months
- Acceptable for short-term storage if refrigeration unavailable, but significant potency loss occurs beyond 6 months.
- Reconstituted, refrigerated, amber vial
- 2–8°C
- 5–8% degradation per month
- 21–28 days
- Standard research storage; use within 28 days for >90% potency. Replace vials every 3 weeks for dose-critical studies.
- Reconstituted, refrigerated, clear vial
- 10–12% degradation per month
- 14–21 days
- UV exposure accelerates methionine oxidation; potency drops faster than amber-stored peptide. Switch to opaque vials.
- Reconstituted, room temperature
- 15–20% degradation in first 14 days
- 7–10 days maximum
- Degradation accelerates exponentially; avoid entirely unless refrigeration is genuinely unavailable. Data consistency suffers.
- Reconstituted, frozen post-mixing
- −20°C
- 8–12% degradation per freeze-thaw cycle
- Not recommended
- Freezing reconstituted peptides causes ice crystal formation that disrupts tertiary structure. One freeze-thaw cycle acceptable in emergencies; repeated cycles denature protein.
