- The following table contrasts storage requirements and stability timelines for IGF-1 LR3 in lyophilised (unmixed) versus reconstituted (mixed) states.
- Lyophilised (Unmixed)
- −20°C (freezer)
- 24+ months when sealed
- Minimal. Desiccant packaging protects against moisture
- None until vial is opened
- Indefinite stability makes lyophilised IGF-1 LR3 the preferred form for long-term inventory; freeze once and leave frozen until ready to use
- Reconstituted in Bacteriostatic Water
- 2–8°C (refrigerator)
- 28 days maximum
- Not applicable. Already in aqueous solution
- High. Every needle draw introduces contamination risk
- 28-day window is a strict ceiling, not a guideline; peptide activity declines measurably after day 21 even under ideal conditions
- Reconstituted in Sterile Water (No Preservative)
- 72 hours maximum
- Not applicable
- Extreme. Bacterial growth begins within 24–48 hours without benzyl alcohol preservative
- Never use sterile water for IGF-1 LR3 intended for multi-day protocols; single-use only
- Room Temperature (Post-Reconstitution)
- 18–25°C
- 4–6 hours before significant degradation
- Contamination accelerates at warmer temperatures
- Acceptable only during active use; return to refrigeration immediately after drawing dose
