Bacteriostatic Water

Street names: BAC water, Bacteriostatic water for injection

Bacteriostatic Water — 30 mL multi-dose vials with benzyl alcohol preservative

What it does

  • Sterile diluent for reconstituting lyophilized peptides and hormones
  • Benzyl alcohol keeps it usable ~28 days after first puncture

Key risks

  • NOT for neonates (benzyl alcohol toxicity)
  • Multi-dose vials contaminated by poor technique — the actual infection source in most peptide-user abscesses
  • Sharing vials spreads blood-borne infections
  • Confusing with plain sterile water (single-use) degrades peptides faster

Overdose signs

  • N/A — not active
  • Infection at injection site days later (contamination)
