  • 1mL bacteriostatic water (200mg/mL)
  • 0.9% benzyl alcohol
  • 28 days refrigerated
  • Low. Benzyl alcohol inhibits bacterial growth
  • High. Small volume allows precise fractional dosing
  • Preferred for most users: maximum potency with extended shelf life and minimal injection volume
  • 2mL bacteriostatic water (100mg/mL)
  • Low
  • Moderate. Larger volume makes fractional doses easier to measure but increases injection volume
  • Best for protocols requiring doses below 100mg or for users who struggle with small syringe measurements
  • 1mL sterile water
  • No preservative
  • 24 hours refrigerated
  • High. No antimicrobial agent present
  • High
  • Only viable if entire vial will be used within 24 hours; impractical for multi-dose protocols
  • Sodium chloride 0.9%
  • Saline solution
  • Variable. Depends on preservative presence
  • Moderate to high
  • Moderate
  • Not recommended: isotonicity doesn't compensate for lack of antimicrobial preservation in multi-dose vials
