Bacteriostatic water for injection is a pharmaceutical product designed to dilute or dissolve medications. In the field of bodybuilding, it is effectively used for growth hormones and peptides, which must be dissolved in an aqueous carrier prior to direct injection.
The bacteriostatic water contains the following components: sterile water, sodium chloride (0.9%), and benzyl alcohol (0.9%). These ingredients prevent the growth of all currently known bacteria.
Why dilute peptides and other medications with water?
Due to its extremely high biological activity, water for injection helps accelerate the absorption process of any substance and enhances its efficacy. Peptides diluted in the correct proportions can have a more pronounced and rapid effect.
It is better to purchase bacteriostatic water for injection rather than standard sterile water: why?
Sterile water does not contain bacteriostatic agents. This means the solution is only suitable for direct injection immediately after the drug has been diluted or dissolved. In contrast, bacteriostatic water extends the shelf life of peptides, thereby resolving the issue of storage after dissolution or dilution.
In sterile water, bacteria can begin to multiply once the rubber stopper of the container is pierced by a needle. This scenario is prevented in bacteriostatic water. Consequently, most peptides diluted with this water can be stored for nearly a month—up to 25–30 days—which is several times longer than when using sterile water or saline. Sealed bacteriostatic water for injection can be stored for at least 12 months without losing its properties or quality.
Application, Instructions
- To prepare the solution, carefully read the instructions for the peptide or other preparation.
- Then, clean the ampoule with alcohol or an antiseptic before adding the preparation and water.
- Use a new insulin syringe to draw the required amount of water and inject it into the vial. Be sure to wait for the drug to dissolve. Shaking the vial is not recommended.
The drug can be used for injection immediately after dissolution.
On average, the prepared solution based on this formulation can be stored at 2–8°C (typically on the top shelf of the refrigerator) for up to 28 days. - Do not heat or freeze the solution.
Are benzyl alcohol and sodium chloride harmful?
At the concentrations found in bacteriostatic water for injection, they are non-toxic and completely safe for injections and wound dressings. Solutions based on bacteriostatic water are equally suitable for intramuscular and subcutaneous injections.
Warning! To maximize the effectiveness of the injection, do not use bacteriostatic water for injection if the drug’s package insert specifies a different solvent. While there are no side effects associated with bacteriostatic water for injection, some medications are most effective when dissolved in other solvents.
