Review of Real Peptides bacteriostatic water 10ml vial. USP-grade, 0.9% benzyl alcohol preservative, priced at $4.80. Essential supply for peptide reconstitution.

Exceptionally low price at $4.80 per vial
USP-grade with 0.9% benzyl alcohol preservative
Ships alongside peptide orders from US stock
Only available in 10ml size
Must be used within 28 days after opening
Key Features
  • Price: $4.80 per vial
  • Volume: 10ml
  • Grade: USP (United States Pharmacopeia)
  • Preservative: 0.9% benzyl alcohol
  • Availability: In stock, US warehouse
  • Multi-use: Yes, up to 28 days after first puncture

At $4.80, this is among the lowest-priced USP-grade bacteriostatic water options available domestically. The 10ml volume pairs directly with 5mg and 10mg peptide vials. Purchasing bacteriostatic water from the same vendor as the peptide allows single-shipment ordering.

What's Inside
  • Base: Sterile water for injection
  • Preservative: Benzyl alcohol at 0.9% concentration
  • Volume: 10ml
  • Standard: USP-grade manufacturing

The 0.9% benzyl alcohol concentration is the standard formulation used across the pharmaceutical industry. This concentration is sufficient to prevent bacterial growth without interfering with peptide stability. The vial uses a rubber stopper sealed with an aluminum crimp cap, allowing repeated needle access.

How to Store and Handle

Store unopened vials at room temperature, away from direct sunlight. No refrigeration is required before first use. After the first puncture, the vial can remain at room temperature for up to 28 days. Some users prefer to refrigerate after opening, though the benzyl alcohol preservative functions at room temperature.

To use, swab the rubber stopper with an alcohol pad. Draw the desired volume of bacteriostatic water into an insulin syringe. Inject the water slowly along the inner wall of the peptide vial. Do not inject directly onto the lyophilized cake. Allow the peptide to dissolve passively. Use a fresh alcohol swab on both the water vial and peptide vial stoppers before each draw.

Real Peptides sells bacteriostatic water in a 10ml vial for $4.80. The product is USP-grade and contains 0.9% benzyl alcohol as the bacteriostatic agent. It ships from US stock. This is the standard reconstitution solvent for lyophilized peptides including BPC-157 and TB-500. We reviewed the product specifications and compared them to industry standards.

Bacteriostatic Water Overview

Bacteriostatic water is sterile water with 0.9% benzyl alcohol added to inhibit microbial growth. The benzyl alcohol allows the water to remain usable for multiple draws over a period of up to 28 days after the vial is first punctured. Without this preservative, sterile water must be discarded after a single use because it has no mechanism to prevent bacterial contamination.

This product is manufactured to USP (United States Pharmacopeia) standards. USP designation confirms the water meets defined criteria for sterility, endotoxin levels, and benzyl alcohol concentration. The 10ml volume is sufficient to reconstitute multiple peptide vials depending on the desired concentration. For concentration calculations, use our BPC-157 reconstitution calculator.

Our Verdict

Real Peptides Bacteriostatic Water earns 4.6 out of 5. Sub-scores: Quality 5.0, Labeling 4.5, Value 4.5, Convenience 4.5. The USP-grade designation, standard 0.9% benzyl alcohol concentration, and $4.80 price point make this a straightforward purchase. There is little to differentiate bacteriostatic water between vendors as long as USP compliance is confirmed.

The $4.80 cost is negligible relative to peptide vial prices. A single 10ml vial can reconstitute multiple peptide vials. Sourcing it from Real Peptides alongside their BPC-157 10mg vial ($43.20) brings the total first-order cost to $48.00 for both components in a single shipment. The product does exactly what it needs to do.

FAQ - Bacteriostatic Water

Why use bacteriostatic water instead of sterile water?

Bacteriostatic water contains 0.9% benzyl alcohol, which prevents bacterial growth after the vial is punctured. Sterile water has no preservative and must be discarded after a single use. If you plan to draw from a reconstituted peptide vial more than once, bacteriostatic water is required. Sterile water is only appropriate for single-use protocols.

How long does an opened vial last?

Up to 28 days after the first needle puncture. The benzyl alcohol preservative maintains sterility for this period when the stopper is swabbed with alcohol before each draw. After 28 days, discard any remaining water and use a fresh vial.

How much water do I need per BPC-157 vial?

Common reconstitution volumes are 1ml or 2ml per peptide vial. The choice depends on the desired concentration. For a 5mg BPC-157 vial, 1ml of bacteriostatic water produces a concentration of 5mg/ml. For a 10mg vial, 2ml produces the same 5mg/ml concentration. A single 10ml water vial is sufficient for 5 to 10 peptide reconstitutions at these volumes.

Is this water USP grade?

Yes. The product is manufactured to United States Pharmacopeia standards. USP designation confirms the water meets defined specifications for sterility, endotoxin content, and preservative concentration. This is the same standard used by compounding pharmacies.
