What water should I use to reconstitute a peptide?

Bacteriostatic water is the usual choice. It has a preservative, so one vial can be used over several weeks. Sterile water also works, but it has no preservative, so it is best for one use. Do not use tap water, spring water, or plain distilled water. They are not sterile and are not meant for this.
