Mechanism of Action
Bacteriostatic Preservation
Benzyl alcohol at 0.9% inhibits bacterial growth by disrupting cell membrane integrity and membrane-associated enzyme systems. This preserves sterility across multiple draws from a single vial over 28 days — essential for any multi-day research protocol. Without this preservative, single-use sterile water would require a new vial with every reconstitution.
Research Findings
Peptide Reconstitution Standard
Bacteriostatic water is the universal standard for lyophilized peptide reconstitution. Compatible with all GLP-1 analogs (Semaglutide, Cagrilintide), structural peptides (BPC-157, TB-500), small peptides (Epithalon, SNAP-8), and copper complexes (GHK-Cu). pH 5.0–7.0 is within the physiological stability range of all listed compounds.
Pharmaceutical reconstitution guidelines
Preclinical Safety Data
Bacteriostatic water is a standard pharmaceutical excipient. Benzyl alcohol at 0.9% is the established bacteriostatic concentration used in countless injectable preparations. Not for use in neonates (benzyl alcohol toxicity in premature infants). Standard adult research use is without concern at this concentration.
Research Dosing Protocols
From published literature — for research reference only.
Standard Reconstitution
Varies by peptide vial size and target concentration
Per peptide reconstitution
For 10mg peptide at 1mg/mL: add 10mL BAC water. For 10mg at 2mg/mL: add 5mL. One 10mL vial typically covers 2–4 peptide reconstitutions.
Reconstitution Guide
- 1
No reconstitution needed — this is the reconstitution vehicle.
- 2
Use a fresh sterile syringe to draw from this vial.
- 3
Inject BAC water slowly down the side of the peptide vial — not directly onto the lyophilized powder.
- 4
Gently swirl the peptide vial — do not shake.
- 5
After first puncture: store at 2–8°C, use within 28 days.
Stacking Guide
All Lyophilized Peptides
Bacteriostatic water is required for every lyophilized peptide in this catalog. Order 1 BAC water vial per 2–3 peptide vials in your protocol.
Frequently Asked Questions
Why do I need bacteriostatic water instead of regular water?
Bacteriostatic water contains 0.9% benzyl alcohol which inhibits bacterial growth following needle insertion. Regular sterile water has no preservative — once punctured, it is considered single-use only. For any research protocol drawing from a vial over multiple days, bacteriostatic water is required.
How much BAC water per peptide vial?
Depends on target concentration. For a 10mg vial at 1mg/mL: add 10mL. For 2mg/mL: add 5mL. For 15mg at 1.5mg/mL: add 10mL. One 10mL BAC water vial typically covers 2–4 peptide reconstitutions.
How long does bacteriostatic water last?
Unopened: until printed expiration date. After first puncture: 28 days when stored at 2–8°C.
