What's the Difference Between Bacteriostatic Water and Sterile Water?

Both are USP-grade sterile water bases — the difference is entirely the added 0.9% benzyl alcohol in bacteriostatic water, which is what gives it its name (bacteriostatic meaning it inhibits bacterial growth rather than being sterile in itself, since both start sterile).

For most of REVIVE LAB UAE's peptide catalog — BPC-157, TB-500, MOTS-c, Semax, Retatrutide, Tesamorelin, NAD+ — bacteriostatic water is the standard reconstitution diluent specifically because research protocols typically draw from the same vial multiple times over days or weeks. GHK-Cu is the notable exception in the catalog, reconstituted with plain sterile water instead, per its own product documentation.

This is a general research-handling comparison, not administration guidance — REVIVE LAB UAE does not provide dosing or protocol instructions for any product.
