Bacteriostatic Water 3mL
3mL sterile bacteriostatic water — the essential reconstitution solvent for all peptide vials.
1–3 mL per peptide vial
Key Benefits
compatible with virtually all lyophilized peptides for reliable reconstitution
0.9% benzyl alcohol prevents bacterial growth for up to 28 days after opening
3mL is the perfect size for single-vial peptide reconstitution (1–3 mL per peptide)
sterile, pyrogen-free, meets USP standards for bacteriostatic water for injection
Recommended Injection Sites
Optimal injection locations for Bacteriostatic Water 3mL based on its route (For reconstitution only — not for direct injection) and pharmacokinetic profile.

Tap a zone to inject
Always inject BAC water slowly down the inner wall of the peptide vial — not directly onto the powder.
N/A — for reconstitution use only.
- Direct injection without dilution
- Shaking the vial after adding BAC water
- Freezing after opening
Active Signaling Pathway
How long will one vial last?
Based on standard research protocols, here's exactly what to expect from a single 3mL vial — and when to plan your next order.
Actual duration may vary based on your specific protocol. Always consult your research guidelines for precise dosing schedules.
Scientific Background
Mechanism of Action
Bacteriostatic Water contains 0.9% benzyl alcohol as a bacteriostatic agent, which disrupts bacterial cell membranes and prevents microbial growth in the reconstituted solution. Unlike sterile water for injection (SWFI), BAC water allows for multiple draws from the same vial without contamination risk. The pH is adjusted to 4.5–7.0 to maintain compatibility with most peptide formulations.
Clinical Context
BAC Water is an essential supply for any peptide research protocol. The 3mL vial size is specifically designed for reconstituting individual peptide vials — add 1–3 mL to your peptide vial depending on desired concentration. Always draw BAC water first, inject slowly down the vial wall, and gently swirl (never shake) to dissolve the lyophilized powder.
Research Highlights
- 0.9% benzyl alcohol concentration is the USP standard for bacteriostatic preservation
- Maintains sterility for up to 28 days after first puncture when stored at 2–8°C
- Compatible with the vast majority of lyophilized peptides — the universal reconstitution standard
- 3mL volume is optimal for single-vial reconstitution of most peptide sizes (2–10mg)
Storage & Reconstitution
Store at room temperature (15–30°C) before opening. After first use, store at 2–8°C. Use within 28 days of first puncture. For peptide reconstitution: draw desired volume into syringe, inject slowly down the vial wall of the peptide vial, gently swirl to dissolve — do not shake.
Add 1–3 mL to lyophilized peptide vial depending on desired concentration. Inject slowly down vial wall. Gently swirl to dissolve. Never shake.
