What Is Bacteriostatic Water for Injection?
Bacteriostatic Water for Injection, USP is a sterile aqueous preparation of Water for Injection containing 0.9% (9 mg/mL) of benzyl alcohol added as a bacteriostatic preservative. Unlike sterile water for injection, which is intended for single use only, the benzyl alcohol preservative inhibits bacterial growth, allowing multiple sterile withdrawals from the same 30mL vial when proper aseptic technique is followed. buy bacteriostatic water 30mL Europe
This preparation is designed solely for parenteral use only after addition of drugs or research compounds that require dilution or must be dissolved in an aqueous vehicle prior to injection. It is supplied in a multiple-dose container from which repeated withdrawals may be made to dilute or dissolve lyophilized peptides for research. buy bacteriostatic water 30mL Europe

How It Works
Bacteriostatic Water for Injection serves as a sterile vehicle for reconstituting lyophilized (freeze-dried) research peptides and diluting concentrated injectable compounds. The 0.9% benzyl alcohol acts as a bacteriostatic agent, meaning it inhibits (but does not kill) bacterial growth in the solution. This preservative property allows a single 30mL vial to be used for multiple withdrawals under sterile technique, typically for up to 28 days after first use.
The water itself has no pharmacological effect — it simply provides a sterile, non-pyrogenic medium that is compatible with most peptide lyophilizates. When added to a vial of lyophilized research peptide powder, the water dissolves the peptide, creating a solution suitable for laboratory research.

Inspect vial to ensure solution is clear and seal is intact and undamaged
-
Swab rubber stopper with 70% isopropyl alcohol prior to each puncture
-
Allow alcohol to dry completely before inserting needle
-
Use a sterile syringe and needle for each withdrawal
-
Label vial with date of first use
Reconstitution Procedure for Research Peptides:
For a typical 5mg or 10mg lyophilized peptide vial:
-
Calculate required volume based on desired concentration
-
Using sterile syringe, draw calculated volume of Bacteriostatic Water
-
Inject solution slowly down the inner wall of the peptide vial (avoid aiming directly at lyophilized powder to prevent degradation)
-
Gently swirl — do not shake — until completely dissolved
-
Refrigerate reconstituted peptide at 2-8°C
-
Use within recommended time frame (typically 30 days for most research peptides)
Storage Recommendations
| Condition | Storage Method |
|---|---|
| Unopened Vial | Store at 20-25°C (68-77°F) controlled room temperature |
| After First Use | Refrigerate at 2-8°C (35.6-46.4°F) |
| Protection | Protect from freezing and excessive heat |
| Discard After | 28 days from first puncture |
| Expiration | See vial label; typically 24-36 months from manufacture |
| Signs of Deterioration | Discard if solution is cloudy, discolored, or contains particulates |
Reconstitution Guidelines
For research peptide reconstitution, here are common volume recommendations:
| Peptide Vial Size | Add Bacteriostatic Water | Resulting Concentration |
|---|---|---|
| 5mg vial | 1.0 mL | 5 mg/mL |
| 5mg vial | 2.0 mL | 2.5 mg/mL |
| 10mg vial | 1.0 mL | 10 mg/mL |
| 10mg vial | 2.0 mL | 5 mg/mL |
| 10mg vial | 3.0 mL | 3.33 mg/mL |
| 15mg vial | 1.5 mL | 10 mg/mL |
| 15mg vial | 3.0 mL | 5 mg/mL |
Safety Considerations and Warnings
Critical Safety Information:
-
NOT FOR USE IN NEONATES: Benzyl alcohol preservative is toxic to newborns and infants. Studies show even small volumes can cause serious adverse effects including gasping syndrome
-
Do Not Inject Alone: Bacteriostatic Water is hypotonic and should never be injected intravenously by itself as this can cause red blood cell hemolysis
-
For Research Use Only: This product is intended for laboratory research and pharmaceutical reconstitution only
-
Not for Epidural or Spinal Use: Should not be used for neuraxial injections
-
Pregnancy Risk Category C: Consult safety documentation before use in pregnancy-related research

Frequently Asked Questions (FAQ)
What is Bacteriostatic Water for Injection?
Bacteriostatic Water for Injection, USP is a sterile, non-pyrogenic preparation of water containing 0.9% (9 mg/mL) of benzyl alcohol as a bacteriostatic preservative. It is designed for diluting or dissolving drugs and research compounds for injection.
What is the difference between Sterile Water and Bacteriostatic Water?
Sterile Water for Injection contains no preservative and is intended for single use only. Bacteriostatic Water contains 0.9% benzyl alcohol, which inhibits bacterial growth and allows for multiple withdrawals from the same vial over up to 28 days.
How long does an opened vial of Bacteriostatic Water last?
Once opened and stored properly at 2-8°C (refrigerated), Bacteriostatic Water can be used for up to 28 days from first puncture. After 28 days, the vial must be discarded.
Why can’t Bacteriostatic Water be used in neonates?
The benzyl alcohol preservative is toxic to newborns and infants. It has been associated with gasping syndrome and other serious adverse effects in neonates. Preservative-free sterile water must be used for neonatal applications.
Can I inject Bacteriostatic Water by itself?
No. Bacteriostatic Water is hypotonic and should never be injected intravenously by itself as this can cause red blood cell hemolysis. It should only be used as a diluent or solvent for approved injectable drugs or research compounds.
How do I reconstitute a research peptide with Bacteriostatic Water?
Calculate the required volume based on your desired concentration. Using a sterile syringe, draw the calculated volume of Bacteriostatic Water and inject slowly down the inner wall of the peptide vial. Gently swirl until completely dissolved. Do not shake.
What is the shelf life of Bacteriostatic Water 30mL?
When stored unopened at controlled room temperature (20-25°C), Bacteriostatic Water typically has a shelf life of 24-36 months from the date of manufacture.
How should I store Bacteriostatic Water after opening?
After first use, refrigerate the vial at 2-8°C (35.6-46.4°F). Always swab the rubber stopper with 70% isopropyl alcohol before each puncture and allow to dry completely.
What concentration of benzyl alcohol is in Bacteriostatic Water?
Bacteriostatic Water for Injection contains 0.9% benzyl alcohol, which equals 9 mg per mL.
Is Bacteriostatic Water suitable for all research peptides?
Most research peptides, including BPC-157, TB-500, GLP-1 agonists (Semaglutide, Tirzepatide), and melanotan peptides, can be reconstituted with Bacteriostatic Water. Always follow specific peptide manufacturer recommendations.
What are the signs that Bacteriostatic Water should not be used?
Do not use if the solution is cloudy, discolored, contains visible particulates, or if the vial seal is broken or damaged.
Can Bacteriostatic Water be frozen?
