- Bacteriostatic Water
- 0.9% benzyl alcohol
- 28 days at 2–8°C
- Excellent. Most peptides
- Multi-dose vials for research protocols lasting 2–4 weeks
- Gold standard for peptide reconstitution
- Sterile Water for Injection (SWFI)
- None
- 24 hours only
- Excellent. All peptides
- Single-dose immediate use or protocols requiring preservative-free formulation
- Use only when benzyl alcohol sensitivity is confirmed
- 0.9% Sodium Chloride (Saline)
- Good. Some peptides precipitate in saline
- Rare. Specific peptides requiring ionic stabilization
- Not recommended for most research peptides
- Acetic Acid Solution (0.1–1%)
- 7–14 days at 2–8°C
- Peptides requiring acidic pH for solubility
- Peptides that aggregate at neutral pH (e.g., some GLP-1 analogs)
- Specialty diluent. Consult synthesis documentation first
