What you receive
One formulation in one size: a 30 mL vial of sterile bacteriostatic water (bac water) preserved with 0.9% benzyl alcohol, sealed under an aluminium crimp with a flip-off cap. Packs differ only in how many vials ship — the vial itself never changes. Full product details.
How it is verified
Every production lot is tested by an independent laboratory for identity, benzyl alcohol concentration, sterility, endotoxins and pH before release. We don’t run those tests ourselves — we publish every laboratory certificate for the shipping lot in full, most recently reported September 4, 2026. Read the current lot’s COA.
How it ships
Orders placed by 2 PM ET, Monday to Friday leave the same business day. Orders ship within the United States via UPS or USPS with tracking, in plain, protective packaging. Shipping & returns policy.
