What "bacteriostatic" means
A bacteriostatic substance stops bacteria from multiplying, rather than killing every one. In bacteriostatic water the preservative is benzyl alcohol. One manufacturer's labelling lists it at 0.9% (9 mg/mL) or 1.1% (11 mg/mL), with a pH of about 5.7 (range 4.5 to 7.0).
Because of the preservative, the container is labelled multiple-dose: it is designed to be opened more than once.
What sterile water is
Sterile water is sterile, nonpyrogenic water with no bacteriostat, antimicrobial agent or added buffer. The labelling says it is supplied only in single-dose containers and that any unused portion should be discarded, because nothing in it holds back contamination once it is opened.

The liquid has to suit the compound
The bacteriostatic water labelling warns that some substances may be incompatible with a given liquid. A preservative, a pH or a salt can change how a compound dissolves or how stable it is. Which liquid suits a material is a question for the manufacturer's or the lab's own data. Research peptides are for laboratory research only and are not approved medicines.
