- Lyophilised Powder Appearance
- Fine white/off-white crystals, loose texture
- Clumped, caked, or yellowed powder
- Clumping indicates moisture exposure and hydrolysis onset. Do not use
- Reconstitution Behavior
- Dissolves completely within 60 seconds with gentle swirling
- Slow dissolution, residue remains, or cloudiness persists
- Incomplete dissolution = compromised peptide structure. Discard vial
- Solution Clarity (Post-Mix)
- Crystal clear, colorless, water-like viscosity
- Cloudy, particulate matter, yellow/amber tint, or precipitate
- Any visible turbidity or color = definitive failure. Do not administer
- Storage Temperature History
- −20°C pre-reconstitution, 2–8°C post-reconstitution
- Room temp exposure >4hrs, freeze-thaw cycles, or >8°C storage
- Temperature excursions above 8°C cause irreversible denaturation
- pH Range (Reconstituted)
- 6.5–7.5 (neutral bacteriostatic water)
- <5.0 or >8.0 (contamination or degradation byproducts)
- pH strips can verify. Deviations beyond 6.0–8.0 range indicate breakdown
- Timeframe Since Reconstitution
- Used within 28 days, refrigerated continuously
- >28 days old or stored inconsistently
- Even clear solutions lose potency after 4 weeks. Adhere to 28-day limit
