The injection site should be the closest accessible subcutaneous tissue to the damaged structure

Bacteriostatic water, by contrast, is designed for the multi-dose case: a powdered product reconstituted into a solution drawn from over multiple days or weeks

The defining difference is the 0.9% benzyl alcohol preservative. Sterile water for injection contains only water no preservatives and is single-use after the vial is opened, because nothing inhibits microbial growth once the seal is broken. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth and allows the vial to be punctured multiple times across an extended period (typically 28 days from first puncture under standard handling). For multi-dose laboratory peptide reconstitution work, BAC water is the standard diluent

Treatment should be initiated under medical supervision to establish the underlying cause and appropriate dosing schedule
