Research Overview

Bacteriostatic Water (BAC Water) is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It is widely used in research laboratories as the standard solvent for reconstituting lyophilised peptide compounds. The benzyl alcohol inhibits microbial growth, allowing reconstituted solutions to be used over multiple sessions without rapid contamination — typically remaining stable for up to 28 days when stored at 2–8°C. BAC Water is compatible with the vast majority of research peptides and is the recommended reconstitution solvent unless a specific alternative is indicated by the peptide's solubility profile. It should be stored at room temperature prior to use and handled under sterile conditions.

Verified order4 September 2026
Extremely pleasant experience for my first order.
I’ve researched products from many different websites across the internet in search for a reliable and trustworthy source and came across this website by pure chance after checking forums and reddit. I was quite novice in my knowledge of peptides and was hoping to find out a bit more before i commited to my first order. Every question i had was answered quickly and perfectly and in all honesty it was far above the level of any customer service i’ve experienced elsewhere. Not only was the ordering process and customer service easy and high quality, but so were the products. This was my first order on this website but since then i’ve returned time and again. Just wanted to share my experience, there’s not many businesses who are so transparent and helpful!
