Bacteriostatic Water: Why Correct Reconstitution Is Critical for Peptide Safety and Efficacy
Bacteriostatic Protection
0.9% benzyl alcohol prevents bacterial contamination for 28+ days after opening — essential for multi-use vials and repeated dosing.
Peptide Integrity
Correct reconstitution preserves the peptide's structure and potency. Wrong solutions can denature peptides, reducing efficacy and safety.
10mL Volume
A 10mL vial provides enough reconstitution solution for multiple peptide vials — practical for running multiple protocols simultaneously.
Same Source
Bacteriostatic water from Apollo Peptide Sciences — pharmaceutical-grade from the same trusted source as all your peptides.

Reconstituting and Dosing Bacteriostatic Water 10mL
Reconstitution Process:
1. Wipe vial tops with alcohol swab
2. Draw desired water volume into sterile syringe
3. Insert needle at angle into peptide vial
4. Inject water slowly against the glass wall (not onto powder)
5. Gently swirl until fully dissolved — never shake
6. Refrigerate immediately
Standard ratio: 1mL per 5mg peptide = 5,000mcg/mL concentration.

Common: 250mcg, 500mcg, 1000mcg
How to read IU: On a standard 1mL insulin syringe, 100 IU = 1mL. Draw to the IU mark shown above. Example: 10 IU = 0.1mL = 100μL.
How Bacteriostatic Water 10mL Works at the Molecular Level
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic agent. It is specifically designed for reconstituting lyophilized (freeze-dried) peptides and other compounds. Using the correct reconstitution solution is essential for maintaining peptide integrity, purity, and sterility.
▸Why Bacteriostatic Water, Not Sterile Water
Sterile water lacks a bacteriostatic preservative — meaning once opened, it can be contaminated within minutes. Bacteriostatic water's 0.9% benzyl alcohol prevents bacterial growth in multi-use vials, making it safe to use the same vial multiple times over 28 days after reconstitution.
For any peptide that requires multiple draws (which is most peptides), bacteriostatic water is essential.
▸Reconstitution Guidelines
Standard reconstitution for most peptides:
→5mg vial: Add 1mL bacteriostatic water = 5,000mcg/mL
→10mg vial: Add 2mL bacteriostatic water = 5,000mcg/mL
→Inject water slowly against the side of the vial (not directly onto the powder)
→Gently swirl — never shake — to dissolve
▸Storage
Reconstituted peptides stored with bacteriostatic water should be refrigerated at 2-8°C and used within 28-30 days.

Clearing Up Bacteriostatic Water 10mL
What is bacteriostatic water and why is it needed for peptides?+
Bacteriostatic water is sterile water containing 0.9% benzyl alcohol — a preservative preventing bacterial growth after opening. It is required for reconstituting lyophilized peptide powders. Unlike regular sterile water (single-use only), bacteriostatic water maintains sterility for 28 days after opening, making it practical for multi-dose peptide vials.
How much bacteriostatic water do I add to a peptide vial?+
Standard: add 1mL of bacteriostatic water to a 5mg peptide vial to create 5,000mcg/mL concentration. For a 250mcg dose, draw 0.05mL (50μL = 5 IU on a standard 1mL insulin syringe). Add water slowly down the inside wall of the vial — never inject directly onto the powder under pressure.
How long does reconstituted peptide last in the fridge?+
Reconstituted peptides in bacteriostatic water last 30 days at 2–8°C (standard refrigerator temperature). Keep away from light. For longer storage, freeze at -20°C where it lasts 6+ months. Avoid repeated freeze-thaw cycles — aliquot into single-use amounts if you need long-term storage.
Can I use regular water instead of bacteriostatic water?+
No — regular tap water is not sterile and will contaminate your peptide. Regular sterile water for injection can be used but only as a single-use reconstitution (the entire vial must be used immediately). Bacteriostatic water is the correct choice for any multi-dose peptide vial.
