What is Bacteriostatic Water?
Bacteriostatic water is composed of sterile water and benzyl alcohol, an organically-derived preservative. The solution’s 0.9% benzyl alcohol content prevents the growth of microbes to resist contamination .
It is commonly applied as a solute or dilutant to therapeutic substances in powder form, enabling aqueous injection. Its pH level rests between 4-5 and 7, averaging at a pH level of 5.7, which makes it an ideal solvent for most parenteral injection routes, namely subcutaneous, intravenous, and intramuscular [1, 2].
Bacteriostatic water is the preferred solvent among most qualified researchers, both easier to produce and more readily available than common alternatives .
A major benefit of bacteriostatic water is its resistance to contamination for up to four weeks (28 days) after its primary use. Thus, single vials can provide multiple doses, and solutions containing the solvent have extended shelf lives with proper storage. Unopened containers remain sterile for up to several years .
It is a go-to choice not only due to the convenience and safety afforded by its preservative content, but because it has low toxicity and mixes favorably with a wide range of compounds [3, 5]. Common solutes include medications, research peptides, and hormones. Specialists in the latter two areas, in particular, tend to recommend bacteriostatic water as the best solvent. It is ideally suited to safety and research purposes and does not interfere with the integrity of most therapeutic compounds [6, 7].
Bacteriostatic water is cautioned for use in some cases, such as in newborns, subjects on certain medications, or those who are allergic to benzyl alcohol [3, 5]. It is not to be injected without a solute mixed in, as this risks the development of hemolysis. Additionally, experts advise against its use for cerebrospinal fluid injections [8, 9].
What is Bacteriostatic Water Used For?
The main applications of bacteriostatic water are as follows:
- It is a solvent that is used to reconstitute lyophilized compounds before injection. These include medications, hormones, and peptides [1, 7, 10].
- It is also mixed with liquid medications to dilute them to the proper concentration before injection .
- Because of its preservative content (0.9% benzyl alcohol), vials of bacteriostatic water can be used to source multiple doses without contamination for up to 28 days, reducing the incidence of infection. This extends the shelf life of properly stored solutions made with bacteriostatic water .
- The solvent does not interfere with most medications and therapeutic substances while providing good solubility .
- Depending on the solute, subject needs, and ideal rate of metabolization, bacteriostatic water is suitable for the following injection routes: subcutaneous, intravenous, and intramuscular .
The proper procedure for reconstituting peptides for injection is as follows :
- Gather the needed materials, including lyophilized peptide powder, bacteriostatic water, a sterile syringe, and alcohol swabs.
- Wipe down the vials with the alcohol swabs to disinfect them.
- Access the bacteriostatic water with the sterile syringe and withdraw approximately 1 mL of the solution.
- Transfer it into the peptide vial gradually, allowing the liquid and powder to properly mix.
- Avoid shaking and stirring to mix the solution, as this can damage the peptides. The liquid will appear transparent when the peptide is fully dissolved.
- If the peptide does not fully dissolve, try a stronger solvent.
- For exact dosage, quantities, and storage, closely adhere to the manufacturer's indications.
The reconstitution of lyophilized hormones, such as GH and HCH, follows a similar method . Particular dosage and storage requirements of reconstituted solutions will vary.
Discontinue use if adverse reactions appear. These include infection, blood clots, and fever .
Benefits of Bacteriostatic Water
Bacteriostatic water for injection is the go-to solvent among many researchers in the scientific community. Here, we will explore the reasons for its popularity.
- The organic bacteriostat agent (09% benzyl alcohol) in bacteriostatic water prevents bacterial growth to fight contamination.
- A single vial of bacteriostatic water is good for multiple doses for 28 days after the initial use, as the preservative content maintains sterility to prevent infection.
- Bacteriostatic water does not require refrigeration.
- An unopened vial can last for several years without contamination.
- It is safely indicated for intravenous injection, subcutaneous injection, and intramuscular injection. This means it is adaptable to different target rates of diffusion and metabolization, as well as subjects with varying conditions.
- Bacteriostatic water can be used to perform injections with a wide range of substances.
- The chemical structure and pH level allow bacteriostatic water to effectively dissolve many types of medications, peptides, and hormones without compromising their integrity.
- Solutions made with bacteriostatic water have prolonged shelf lives.
- Bacteriostatic water is easily sourced from trusted manufacturers.

Bacteriostatic Water vs. Sterile Water
Another solvent that is often used in injections is sterile water. It is water that has undergone a thorough distillation, purification, and disinfection process to be free of contaminants. Unlike bacteriostatic water, sterile water has no added preservatives.
Here, we will examine the similarities and differences between bacteriostatic water and sterile water to help you select the best solvent for your research .
These are the common traits of bacteriostatic water and sterile water in three key areas—their formulations, uses, and precautions :
- Both are sterile solvents formulated for use in performing injections.
- Sterile water is present in both, as bacteriostatic water is composed of sterile water with added benzyl alcohol.
- The solutions have similar acidity levels. The average pH level of sterile water is 5.5, and the average pH level of bacteriostatic water is 5.7.
- Both substances are produced in regulated settings that meet USP (US Pharmacopeia) protocols and are classed as pharmacological-grade.
- Both substances are applied as solvents or dilutants to achieve aqueous suspension of compounds intended for intravenous, subcutaneous, and intramuscular injections.
- They are both commonly used with peptides, hormones, and medications as solutes.
- Both can cause hemolysis if injected without a solute.
- Neither substance is indicated for use in spinal injections, or subjects taking certain medications.
Now, let’s weigh their differences in these key areas :
- They are chemically distinct, as bacteriostatic water has a 0.9% benzyl alcohol content, while sterile water does not. Thus, sterile water has no bacteriostat agent to fight contamination.
- Their pH ranges differ. Bacteriostatic water has a pH of 4.5-7, and sterile water has a pH of 5.0-7.0.
- Sterile water is less readily available and more difficult to produce [13, 14].
- Bacteriostatic water is considered a more efficient solvent due to its benzyl alcohol content .
- Sterile water is contaminated after a single use and is available in mono-dose vials. On the contrary, bacteriostatic water remains sterile for weeks after initial use, allowing multiple doses to be drawn from a single vial [4, 5].
- Bacteriostatic water solutions are safe for use for an extended period of time, while sterile water solutions are to be thrown away with one use [12, 15].
- Subjects that are allergic to benzyl alcohol should not use bacteriostatic water.
- Some drugs interact differently with each solvent and they are not considered interchangeable.
This close comparison reveals that while these two solvents share some features, the benefits of bacteriostatic water exceed those of sterile water in most contexts.
Does Bacteriostatic Water Need to Be Refrigerated?
Bacteriostatic water does not require refrigeration. Its preservative content prevents contamination for approximately 28 days after opening, and sealed vials can be kept in proper storage for several years without going bad.
- Keep both opened and unopened vials at a temperature of 60-80° F.
- Store the vials in a low-lit area, such as a cabinet, away from sunlight.
- Do not place items on top of bacteriostatic water vials, as this can rupture them and damage the contents.
Storage conditions are subject to change when bacteriostatic water is mixed with various solutes. Closely follow all manufacturer indications for proper storage.
How to Make Bacteriostatic Water
While it may seem like a simple task to make bacteriostatic water, experts strongly warn against this practice. Attempting to produce bacteriostatic water outside of a regulated setting is likely to lead to contamination and infection. The home, for example, is a highly bioactive environment that is rife with fungi and microorganisms, such as the deadly MRSA bacteria .
Instead, it is best practice to source bacteriostatic water for injection from reputable producers who adhere to proper safety measures.
While one should always exercise caution, it is especially important to identify quality sources of materials destined for injection, as contamination could cause serious illness.
