Reconstitution Water
A single-component research diluent supplied for controlled laboratory environments. Reconstitution Water is a sterile preparation of water for injection containing 0.9% benzyl alcohol as a bacteriostatic preservative, the same specification widely used to return lyophilized (freeze-dried) research peptides and proteins to a stable liquid state. It is intended strictly for research use in biochemical and pharmacological model systems, and is not for human or animal use.
Add Reconstitution Water to your order and reconstitute every vial the right way, the first time.
Composition
- Sterile water for injection
- 0.9% benzyl alcohol (bacteriostatic preservative)
- Available sizes: 3 mL and 10 mL sealed research vials
- Appearance: Clear, colorless solution
The benzyl alcohol inhibits bacterial growth rather than killing microbes outright, which is what allows a single vial to be accessed multiple times during a research protocol without rapid contamination. This "bacteriostatic" behavior is distinct from bactericidal action and is the reason it is the preferred diluent over plain sterile water for multi-withdrawal work.
Research Focus (non-clinical)
- Returning lyophilized research peptides and proteins to solution for in-vitro study
- Preparing multi-withdrawal stock solutions where repeated sterile access is required
- Solubility, stability, and reconstitution profiling under controlled storage conditions
- Assay preparation and dilution series for HPLC / LC-MS workflows
For qualified research professionals and institutional laboratories. Not for human use.
Why researchers choose bacteriostatic reconstitution water
When a peptide is manufactured it is freeze-dried into a dry powder for stability in transit. Before it can be studied it has to be dissolved, and the choice of diluent matters. Sterile water and bacteriostatic water for injection are both used, but only the bacteriostatic form supports repeated withdrawals from the same vial over an extended bench window. That makes it the standard diluent for research peptides that are studied across many samples from a single reconstituted vial, such as recovery compounds like BPC-157 or growth-hormone secretagogues like CJC-1295.
To reconstitute, the diluent is directed slowly down the inner wall of the vial rather than sprayed directly onto the powder, which protects the peptide structure while it goes into solution.
Order your Reconstitution Water alongside your peptides so every vial arrives ready to prepare.
Documentation & Quality Assurance
Each lot is sourced through our verified supply chain with an emphasis on traceability and quality control. Every product is third-party tested and GMP certified, and we work to obtain and maintain analytical documentation and a Certificate of Analysis (COA) for each batch as part of our ongoing quality process. These documents are reviewed internally and displayed as they become available. Independent third-party testing is performed on select lots to confirm identity, sterility, and alignment with our internal specifications.
Quality & Manufacturing
Materials are sourced from vetted manufacturing partners who follow quality systems consistent with ISO and cGMP principles. Each supplier is reviewed for reliability, documentation integrity, and transparency in testing. All research materials are sealed for integrity and packaged for stability during storage and transport. Peptides Please ships to the USA and Canada and backs every order with a 30-day guarantee.

Frequently Asked Questions
What is reconstitution water?
Reconstitution water is a sterile diluent used to dissolve lyophilized (freeze-dried) research peptides and proteins into a liquid solution. On this site it refers to bacteriostatic water for injection, sterile water containing 0.9% benzyl alcohol as a preservative.
Is reconstitution water the same as bacteriostatic water?
Yes. "Reconstitution water" is the name we use for bacteriostatic water for injection, the 0.9% benzyl alcohol sterile water that laboratories use as a multi-withdrawal diluent.
What sizes does reconstitution water come in?
Reconstitution Water is available in 3 mL and 10 mL sealed research vials, so you can match the volume to the number of peptide vials in your protocol.
Why use bacteriostatic water instead of plain sterile water?
Plain sterile water has no preservative, so a vial should be used once. The benzyl alcohol in bacteriostatic water inhibits bacterial growth, which supports repeated sterile access to a single reconstituted vial across a research protocol.
Is this product for human use?
No. All Peptides Please products, including Reconstitution Water, are supplied strictly for laboratory research use and are not for human or animal use.
Do you ship reconstitution water to Canada?
Yes. Peptides Please ships research materials to both the USA and Canada.
