Bacteriostatic Water (BAC Water) is a sterile water solution containing 0.9% benzyl alcohol as a preservative, commonly used to reconstitute lyophilized (freeze-dried) peptides, hormones (e.g., HGH, peptides like BPC-157 or TB-500), or other injectables. The 30ml volume is larger than typical vials (often 10ml or less), so it’s likely for bulk reconstitution or multiple doses—ensure your product specifies this.

Key Safety Notes

• Sterility First: Use alcohol swabs on vials/stops, sterile syringes/needles. Work in a clean environment.
• Dosage Precision: Always calculate based on your compound’s label (e.g., mg per vial). Over-dilution reduces potency; under-dilution risks high concentrations.
• Almacenamiento: Refrigerate reconstituted solution (2-8°C/36-46°F). Discard after 28 days due to benzyl alcohol limits. Do not freeze.
• Not for Drinking: Injection-only. Consult a doctor/pharmacist for medical use.

Standard Reconstitution Steps

1. Gather Supplies:

2. Calculate Volume:
   • Decide desired concentration. Common examples:

• Formula: Volume (ml) = Desired Conc. (mg/ml) / Total mg × Preference.
  • Example: For 5mg vial at 2mg/ml → 5mg / 2mg/ml = 2.5ml BAC Water.
• With 30ml BAC, you can reconstitute multiple vials (e.g., 10 × 3ml doses).

3. Step-by-Step Process:
   1. Swab BAC Water and powder vial tops with alcohol.
   2. Draw air into syringe equal to water volume needed (e.g., 2ml air).
   3. Inject air into BAC vial to equalize pressure.
   4. Draw exact water volume (e.g., 2ml)—avoid bubbles.
   5. Slowly inject water along powder vial wall (don’t blast center to avoid foaming).
   6. Gently swirl/roll vial—never shake. Let sit 5-10min if needed.
   7. Solution is ready when clear. Draw dose with new syringe.

Example for Common Peptides

Troubleshooting

• Cloudy/Foamy? Let settle; if persists, discard.
• Precipitate? Wrong pH or expired—discard.
• Pain on Inject? Too concentrated; dilute more next time.
