Albert's Verdict
Proper reconstitution starts with proper BAC water. USP-grade, 0.9% benzyl alcohol — the right vehicle preserves peptide integrity from the moment you reconstitute.

Bacteriostatic Water is a research compound. Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a preservative, inhibiting bacterial growth for 28-day multiple-use vial compatibility in laboratory peptide reconstitution applications. Common synonyms in the literature include BAC water and Sterile water with benzyl alcohol.
Investigation of Bacteriostatic Water to date is sparse, with the majority of citations concentrated in animal models and in-vitro assays rather than randomized controlled human trials. Published work referencing Bacteriostatic Water spans peptide reconstitution, multiple-use vial compatibility, and laboratory standard. None of this material describes therapeutic outcomes in humans, and BioInfinity does not sell, market, or provide dosing guidance for Bacteriostatic Water outside laboratory research.
Because this SKU is used as a reconstitution vehicle rather than a peptide, storage is straightforward: keep the sealed vial refrigerated (2–8 °C) prior to first draw, and once punctured discard after 28 days per USP recommendations for benzyl-alcohol-preserved sterile water. Do not freeze — freezing can compromise the vial seal and permit contamination on thaw. Every draw should use a fresh sterile needle to preserve the bacteriostatic action of the 0.9% benzyl alcohol preservative.
Bacteriostatic water is not a peptide, so third-party HPLC purity is not applicable. Instead every lot ships with a Certificate of Analysis documenting sterility, endotoxin (LAL) testing, and preservative concentration confirming the labelled 0.9 % benzyl alcohol level. The COA is uploaded to the public /coa-library and cross-referenced by lot number on the outer label.

Easy reconstitution, excellent quality and purity. Well packaged.
I have ordered from Bioinfinity Lab several times now and they are awesome. Products arrive quickly and purity is easily verifiable through coa's. Highly recommend them if you are looking for a good consistent source.
Worked as it should so no complaints!
I have been using this to mix the GPL3R for 3 months - this company is great to deal with.
Showed up quickly and did what it needed to do. Works well!
