Bacteriostatic Water 10mL
10mL sterile bacteriostatic water — ideal for multi-peptide protocols and extended research runs.
Key Benefits
one 10mL vial reconstitutes 3–10 individual peptide vials
0.9% benzyl alcohol prevents bacterial growth for up to 28 days after opening
ideal for researchers running stacked or extended protocols
sterile, pyrogen-free, meets USP standards for bacteriostatic water for injection
Active Signaling Pathway
Proposed Mechanism
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.
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
- 10mL volume supports reconstitution of 3–10 individual peptide vials from a single BAC water vial
- Ideal for researchers running stacked protocols requiring multiple simultaneous reconstitutions
Evidence is primarily from in vitro cell studies and animal models. Human data is limited or absent.

Based on standard research protocols, here's exactly what to expect from a single 10mL vial — and when to plan your next order.
Vial supply estimate is based on standard research protocol volumes. Actual duration will vary based on your specific protocol design.
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
The 10mL BAC water vial is the preferred choice for researchers running multi-peptide stacks or extended protocols. A single 10mL vial can reconstitute 3–10 peptide vials depending on desired concentration, making it the most cost-efficient option for active research programs.
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
- 10mL volume supports reconstitution of 3–10 individual peptide vials from a single BAC water vial
- Ideal for researchers running stacked protocols requiring multiple simultaneous reconstitutions
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.
Key Studies
USP standards for bacteriostatic water for injection
United States Pharmacopeia
0.9% benzyl alcohol concentration is the USP standard for bacteriostatic preservation, maintaining sterility for 28 days after first puncture.
FDA guidance on benzyl alcohol in injectable products
FDA
Benzyl alcohol at 0.9% is safe for adult use as a bacteriostatic preservative; contraindicated in neonates due to gasping syndrome.
Pharmacokinetics
Bioavailability indicates how much of the compound reaches systemic circulation. Peak plasma is when blood levels are highest. Half-life determines dosing frequency — compounds with short half-lives require more frequent dosing to maintain therapeutic levels.
The volume of distribution reflects how widely the compound distributes into tissues. A higher Vd means the compound concentrates in tissues rather than staying in plasma.
Receptor Binding Profile
No pharmacological receptor activity — used exclusively for peptide reconstitution
Side Effects & Adverse Events
- Injection site reactions if used incorrectly
- Benzyl alcohol sensitivity (rare)
- Benzyl alcohol toxicity in neonates/premature infants (gasping syndrome — do not use in newborns)
