What is bacteriostatic water?

Bacteriostatic water is the sterile solvent used to reconstitute lyophilized (freeze-dried) peptides. It is water for injection with 0.9% benzyl alcohol added — a preservative that lets you draw from the same vial multiple times over several weeks.

What it is

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol. The benzyl alcohol is bacteriostatic — it stops bacteria from growing — which is what makes the vial safe to use across multiple draws, unlike plain sterile water (which is single-use). It is the standard diluent for reconstituting peptides supplied as a dry powder.

How to use it

You add bacteriostatic water to a lyophilized peptide vial to dissolve the powder into an injectable solution. How much you add sets the concentration — our free reconstitution calculator works out the exact draw volume for any vial and water combination.

Quality and sourcing

Every batch of Azzurri Wellness bacteriostatic water is compounded through a Registered 503B outsourcing facility under GMP-compliant processes, HPLC-tested for purity and potency, and third-party lab verified. Shipped cold-pack when needed to protect stability.

Store reviews — about service and delivery, not about Bacteriostatic Water.

Jul 4, 2026

Excellent experience! Shipping was incredibly fast, and everything arrived securely packaged and exactly as expected. What really stood out was the customer service—they were quick to respond, professional, and very helpful throughout the process. It’s refreshing to deal with a company that clearly values its customers, as I had many questions prior to purchase. I’ll definitely be ordering from them again and highly recommend them based on the outstanding service and fast delivery. Also the website maps out what each peptide does, just awesome all around
