- Bacteriostatic Water (Standard)
- 0.9% benzyl alcohol
- 60–90 seconds
- 28 days at 2–8°C
- Allergic reaction to benzyl alcohol (rare)
- Preferred method. Longest stability, lowest contamination risk, allows multi-dose use
- Sterile Water (Preservative-Free)
- Pure H₂O for injection
- 45–60 seconds
- 24 hours at 2–8°C
- Bacterial contamination after 24h
- Use only for single-dose immediate administration. Not suitable for research protocols requiring repeat dosing
- Sodium Chloride 0.9%
- Normal saline
- 90–120 seconds
- 14–21 days at 2–8°C
- Slower dissolution, higher ionic strength may affect some peptides
- Acceptable alternative if bacteriostatic water unavailable. Shorter shelf life than bacteriostatic
- Direct Injection (No Pre-Mixing)
- N/A
- Complete protocol failure
- Never inject lyophilised powder directly. Causes severe injection site reactions and zero bioavailability
