Buy Bacteriostatic Water for Peptide Reconstitution
Bacteriostatic Water is a sterile solution of water for injection containing a bacteriostatic component, intended for reconstitution of peptides and other lyophilized compounds before use.Provides solution stability and reduces the risk of bacterial growth during multiple withdrawals from the same vial.Used for preparation of injectable peptide solutions and other compounds.Allows reconstituted products to be stored for extended periods when proper storage conditions are maintained.Suitable for cycle-based use and multiple withdrawals from a single vial.

Customer Reviews
Giulia — ★★★★★
never had a contamination issue using peptex BAC water across dozens of reconstitutions over 18 months. that track record matters when youre injecting peptides
Javier K. — ★★★★★
my pharmacist background makes me particular about reconstitution solvents. peptex BAC water meets the standards id expect. no pyrogens, proper preservation, clean. exactly what it should be
Lina — ★★★★★
Quality BAC water is the foundation of proper peptide use. Cheap BAC water with inconsistent benzyl alcohol concentration can compromise your entire protocol. Peptex gets this right every time. Seven orders, all identical quality.
Jack V. — ★★★★
Good product, reasonable price. Wish the vials were slightly larger but the current size works fine for most peptide courses. Consistent quality across orders.
Ragnhild — ★★★★★
always order BAC water alongside my peptide orders. peptex version reconstitutes perfectly every time. no injection site irritation which ive had with cheaper BAC water from other sources

Frequently Asked Questions
What is bacteriostatic water and why is it needed?
Bacteriostatic water (BAC Water) is sterile water for injection with a bacteriostatic component (typically 0.9% benzyl alcohol), intended for reconstituting peptides and other lyophilized (dry) compounds before use. The bacteriostatic component inhibits bacterial growth, allowing multiple uses from a single vial over an extended period (up to 90 days) without loss of sterility.
How to properly use bacteriostatic water for peptide reconstitution?
Draw the required amount of BAC Water into a sterile syringe, slowly inject the water into the peptide vial along the inner wall (not directly onto the powder), gently swirl the vial in circular motions until fully dissolved — never shake or agitate. After reconstitution, store in the refrigerator at 2–8°C. The prepared solution is viable for up to 90 days.
Can regular water for injection be used instead of bacteriostatic water?
Regular water for injection (sterile water without preservative) can be used for peptide reconstitution, but it should only be used once — the entire solution must be used in a single session, as without the bacteriostatic component, the solution quickly loses sterility. Bacteriostatic water is the standard for multi-use peptide reconstitution, as it ensures stability and sterility for up to 90 days.
Where to buy bacteriostatic water?
Bacteriostatic water is available at peptex.shop with delivery across Europe. Recommended to purchase together with peptides for proper reconstitution and storage.
