Bacteriostatic Water vs Sterile Water
What is bacteriostatic water?
Bacteriostatic water is a highly purified and sterilised tye of water that is used to dilute medications meant for injection. It contains 0.9% benzyl alcohol. The benzyl alcohol is added to ensure that bacteria does not grow in the water as diluting medications with tainted water can have some severe consequences. The addition of the benzyl alcohol is what makes bacteriostatic water ideal for injection either intramuscularly, intravenously or subcutaneously.
Once a vial of bacteriostatic water is opened, the benzyl alcohol will usually prevent the growth of bacteria for up to 28 days.
Are there any side effects to using bacteriostatic water?
Although bacteriostatic water is mostly safe, there are some side effects associated with its use. That said, the side effects are very rare but you ought to be aware of them. One caveat though, you should never inject bacteriostatic water without mixing in any medications. This is because the benzyl alcohol in it causes the break down of red blood cells. Other reported side effects of using bacteriostatic water include tissue death, venous thrombosis, infection at the injection site, fever, abscess formation as well as a febrile response.
It goes without saying that if you use bacteriostatic water and experience any side effects, it would be better to discontinue its use and consult a doctor.
What is sterile water?
As with bacteriostatic water, sterile water is highly purified and as the name implies, sterile. There are no additives or preservatives added to it. Once a vial of sterile water is open, it ought to be used completely at once or used once and discarded. This is one of the reasons that vials of sterile water usually contain a few millilitres of the liquid.
Are there any side effects to using sterile water?
For the most part, no. That said, a small percentage of people report inflammation at the injection site if sterile water is used to dilute peptides that are to be injected intramuscularly. Other side effects include low blood sodium also known as hyponatremia, fluid overload, allergic reactions(tightness in the chest, swelling of the mouth, face and lips) fever, redness at the site of injection as well as electrolyte imbalance. As with bacteriostatic water, should you experience any side effects, you are advised to stop using sterile water for injections and talk to a doctor immediately.
Which is better, bacteriostatic water or sterile water?
For the most art, bacteriostatic water is better when diluting any medication. This is because it offers better solubility for the most part. It is also advised that if you are experimenting with new peptides, it is always best to use bacteriostatic water to dilute the peptides.
If you have any issue diluting any peptides in bacteriostatic water, you are advised to add a small amount of 10% aqueous acetic acid for basic peptides and aqueous ammonia for acidic peptides.
Most peptide packages contain mixing instruction. It is always best to read those before trying to reconstitute the peptides. It could be potentially harmful to try to reconstitute a peptide meant for mixing with bacteriostatic water with sterile water and vice versa. See our consumables here
