Laboratory Supplies and Bacteriostatic Water
Our supplies category stocks the laboratory consumables that support peptide research work. Bacteriostatic Water is offered in 10 mL and 30 mL vials as a sterile diluent preserved with 0.9% benzyl alcohol, supplied for laboratory research use only and not for human or veterinary use.
Bacteriostatic water is the diluent most commonly specified in peptide research protocols, because the benzyl alcohol preservative inhibits bacterial growth and allows a reconstituted vial to be sampled more than once over a series of bench experiments. Lyophilized research peptides are reconstituted with a measured volume of diluent so that an investigator can calculate a working concentration for an in-vitro assay, and the choice of diluent affects both solubility and the stability of the sequence across the life of a study.
How researchers use this diluent
Laboratories generally pair bacteriostatic water with the lyophilized peptides in our cellular modulation, hormone signaling, metabolic and structural pathway categories. Common bench practice is to add diluent slowly against the wall of the vial rather than directly onto the peptide cake, to swirl rather than vortex, and to aliquot the resulting solution so repeated freeze-thaw cycles do not degrade the material. Unpreserved sterile water and saline solutions are alternatives, though neither resists microbial growth once a vial has been entered.
Vials ship from the United States, and the peptides this diluent is used with are manufactured to a minimum 99% HPLC purity specification, with batch certificates of analysis (COAs) published on many product pages. Consistent diluent quality matters for reproducibility: contamination or an unexpected preservative concentration introduces a variable that is very difficult to detect later in an experiment.
The bacteriostatic water sold here is a laboratory reagent. It is not a medicine, not a medical device and not for any use involving people or animals, and it is supplied only to research professionals, universities and commercial laboratories.

Frequently asked questions
What is bacteriostatic water and what does it contain?
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, an agent that inhibits bacterial growth inside the container after its seal has first been entered. That property is why laboratories select it as a diluent instead of plain sterile water when a container will be accessed more than once. True Form Peptides stocks it as a laboratory supply, sold for research use only.
What is the difference between the 10 mL and 30 mL bottles?
Only the volume differs between them. Both bottles hold the same 0.9% benzyl alcohol laboratory diluent, so the choice comes down to how much a laboratory expects to draw before the container is discarded. The smaller size limits how long a single container stays in use, while the 30 mL suits higher-throughput work. Neither presentation is supplied for human or veterinary use.
Do you provide instructions for mixing peptides with bacteriostatic water?
No. True Form Peptides does not provide dosing, reconstitution or administration guidance, because every product sold, laboratory diluents included, is supplied for research use only. The product page states the composition, the fill volume and the preservative concentration, and nothing further. Any handling procedure is determined by the receiving laboratory under its own standard operating procedures and the requirements of the study being conducted.
How should bacteriostatic water be stored, and how quickly does it ship?
General laboratory practice is to keep the sealed bottle upright at controlled room temperature, away from direct light, and to record the date its seal was first entered. Orders ship within the United States only and typically enter processing within one to two business days before tracking is issued. The item is stocked as a laboratory supply and is not intended for human or veterinary use.
