Why Third-Party Testing Matters

PureBac sources from a GMP-compliant, FDA-registered manufacturing facility and requires independent laboratory verification before any lot is released. You get the actual results — not a self-certification.

Common Questions

Bacteriostatic water is sterile water preserved with 0.9% benzyl alcohol. The preservative inhibits bacterial growth after the vial is opened, making it safe for multi-dose use. It's the standard diluent for reconstituting lyophilized peptides and proteins for injection.

Once punctured, use the vial within 28 days. Store at room temperature (20–25°C) or refrigerated. Always use a new sterile needle for each draw to maintain the sterility of remaining contents.

Plain sterile water is single-use only — once opened, it can't safely be reused. Bacteriostatic water contains 0.9% benzyl alcohol which prevents bacterial growth after puncture, making it safe for multi-dose protocols over up to 28 days.
