Sterile bacteriostatic water (0.9% benzyl alcohol) for reconstituting lyophilised research peptides. Multi-dose compatible, GMP-produced, 3ml vial.
Description
Bacteriostatic Water 3ml Vial for Research Use
Bacteriostatic Water (0.9% benzyl alcohol in sterile water for injection) is the standard reconstitution solvent used in peptide and protein research. The addition of 0.9% benzyl alcohol inhibits bacterial growth, allowing the solution to be used multiple times from a single vial without compromising sterility — making it the preferred choice for laboratory reconstitution of lyophilised research compounds.
Key Properties
- Sterile water preserved with 0.9% benzyl alcohol as a bacteriostatic agent
- Multi-dose compatible — inhibits microbial growth between uses
- Isotonic formulation suitable for dissolving lyophilised peptides and proteins
- Standard solvent for GLP-1 agonists, growth hormone peptides, and other research compounds
Quality & Documentation
Each 3ml vial of Bacteriostatic Water is produced under GMP conditions, supplied sterile and sealed for laboratory use. Suitable for reconstituting all lyophilised peptides in the Life Peptides catalogue.

Research Overview
Bacteriostatic Water is a pharmaceutical-grade sterile water preparation containing 0.9% benzyl alcohol as a preservative. Unlike standard sterile water for injection (which is single-use), bacteriostatic water is formulated for multi-dose use — the benzyl alcohol prevents bacterial contamination between withdrawals, making it the industry standard for laboratory reconstitution of lyophilised peptides and proteins.
In peptide research settings, bacteriostatic water is used to reconstitute lyophilised compounds including GLP-1 receptor agonists (Semaglutide, Tirzepatide, Retatrutide), growth hormone secretagogues (Ipamorelin, CJC-1295), tissue repair peptides (BPC-157, TB-500), and coenzymes such as NAD+. The neutral pH and isotonic composition of bacteriostatic water help preserve peptide integrity during and after reconstitution.
Reconstituted peptide solutions stored at 2–8°C in bacteriostatic water typically remain stable for 21–28 days, compared to shorter windows achievable with plain sterile water. This extended stability window is critical for research protocols requiring repeated sampling from the same vial.
Research Applications
- Reconstitution of lyophilised research peptides and proteins
- Multi-dose research protocols requiring repeated vial access
- Preparation of peptide stock solutions for in-vitro studies
- Compatible with all lyophilised compounds in the Life Peptides catalogue
