BAC water

What is Bacteriostatic Water (BAC Water)?

Bacteriostatic Water is sterile water that includes a bacteriostatic agent (usually benzyl alcohol) to prevent the growth of bacteria in the solution once opened. Unlike sterile water for injection (SWFI), BAC Water is designed for use in multiple-dose vials because it inhibits bacterial contamination. This makes it ideal for reconstituting peptides or hormones that are stored in lyophilized (powder) form, such as peptides like Semax, BPC-157, or Melanotan 2.

Key Benefits and Uses:

• Prevents Bacterial Growth: The addition of benzyl alcohol allows the water to resist bacterial contamination after the vial is opened, making it safe to use over an extended period (typically 28 days after opening, but consult product specifics).

• Reconstitution of Peptides: BAC Water is commonly used to reconstitute peptide powders that are often sold in a lyophilized state, ensuring proper dilution and making them suitable for injection.

• Dilution of Medications: BAC Water can also be used to dilute other injectable medications or hormones, especially when precise dosages are required.

How to Use Bacteriostatic Water (BAC Water):

1. Reconstituting Peptides:

   • For peptides in lyophilized powder form (e.g., Melanotan 2, CJC-1295, PT-141), use BAC Water to dissolve the powder into a liquid form.

   • Use a sterile syringe to withdraw the required amount of BAC Water (usually a few milliliters) and inject it slowly into the vial with the peptide powder.

   • Gently swirl the vial to dissolve the powder completely. Do not shake it, as shaking may damage the peptide or cause foaming.

2. Storage:

   • After reconstitution, store peptides or medications in the refrigerator (2°C–8°C) to maintain stability and avoid degradation.

   • Bacteriostatic water is typically stable for up to 28 days once opened, but it’s always a good idea to check the specific product’s guidelines for expiration dates.

3. Injection:

   • After reconstitution, the peptide or medication can be drawn from the vial and injected using a sterile syringe and needle.
