- Bacteriostatic Water (0.9% benzyl alcohol)
- 28 days refrigerated
- 2–8°C
- Yes. Up to 20 punctures
- ~290
- Industry standard for multi-dose peptide protocols. Longest validated stability window with documented safety profile
- Sterile Water for Injection (preservative-free)
- Single use only (no inhibition)
- No. Discard after single draw
- ~285
- Required for large single-dose reconstitutions or patients with benzyl alcohol sensitivity. Zero contamination protection after opening
- 0.9% Sodium Chloride (preservative-free)
- Single use only
- No
- ~308
- Isotonic advantage for some peptides but no bacteriostatic protection. Suitable only for immediate single-dose use
- Bacteriostatic Saline (0.9% NaCl + 0.9% benzyl alcohol)
- ~310
- Combines isotonicity with bacteriostatic properties. Preferred for peptides sensitive to hypotonic solutions but functionally equivalent to bacteriostatic water for most compounds
