Key Features
  • Price: $4.80 (sale)
  • Volume: 10 ml per vial
  • Grade: USP
  • Preservative: 0.9% benzyl alcohol
  • Multi-dose: Yes, up to 28 days after first puncture
  • Shipping: $9.95 standard; free over $250; 2-4 business days
  • Returns: All sales final

In terms of cost, $4.80 is a reasonable price for a supply. A 10 ml vial can provide enough amount of water for more than one peptide reconstitution since the amount of water selected for each reconstitution can vary. Using 2 ml water per peptide vial will mean one vial of bacteriostatic water will be sufficient for five reconstitutions.

What's Inside
  • Base: Sterile water for injection
  • Preservative: Benzyl alcohol at 0.9% concentration
  • Volume: 10 ml
  • Grade: USP (United States Pharmacopeia)

0.9% benzyl alcohol is the industry standard and is widely accepted in the pharmaceutical and research industry. Its antibacterial properties allow the solution to be safe to use repeatedly, while also not exceeding the threshold where it may impair some of the research operations.

How to Store and Handle

Store unopened vials at room temperature in a clean, dry environment away from direct sunlight. The product does not require refrigeration before first use. Once the stopper has been punctured, store the vial at room temperature or at 2-8C and use within 28 days.

Before each use, wipe the rubber stopper with an alcohol swab and allow it to dry for at least 10 seconds. Draw the desired volume with a sterile syringe. To reconstitute a peptide, inject the water slowly along the inner wall of the peptide vial. Do not aim directly at the lyophilized cake. Let the peptide dissolve passively without shaking. For a step-by-step walkthrough, see our reconstitution guide and calculator.

Real Peptides Bacteriostatic Water refers to a 10 ml vial of sterile purification water, stated as USP standard water with 0.9% benzyl alcohol, made available for $4.80 in current sale offers. This product is categorized under reconstitution supplies rather than a peptide. It helps dissolve lyophilized peptide powders into injectable forms for research purposes, including BPC-157 and TB-500. We examined information available about the product specifications, its prices, and how it is used in the context of the peptide research supply chain.

Bacteriostatic Water Overview

Bacteriostatic water is distilled water with a trace percentage of benzyl alcohol of about 0.9%, which prevents the growth of microorganisms. Using the preservative enables users to withdraw water from the vial multiple times within 28 days. In laboratory applications, it is the conventional solvent used in the process of making lyophilized peptides.

Understanding the difference from sterile water is essential. Sterile water does not contain any types of preservatives and shall be used in one session after opening the ampoule. While bacteriostatic water allows using it several times due to the antibacterial effect of benzyl alcohol. This product is considered USP-grade water meaning that it has the requirements of the United States Pharmacopeia. Please refer to our Real Peptides BPC-157 review for the information on the peptides which use this kind of water for reconstituting.

Our Verdict

Real Peptides Bacteriostatic Water has a solid score of 4.3 from a total of 5. It has high ratings in various categories: 4.5 for Quality, 4.5 for Labeling, 4.5 for Value and 3.5 for Availability. The name of USP-grade, its formula infused with 0.9% benzyl alcohol, and price of $4.80 make this water an excellent product. It is perfectly suited with the BPC-157 product of Real Peptides for a complete system of reconstitution.

The only notable limitation is the shipping cost structure. At $9.95 for standard shipping, ordering a single $4.80 vial of bacteriostatic water nearly triples the effective cost. The practical approach is to add it to a peptide order. Combining this vial with a BPC-157 10 mg vial at $43.20 brings the total to $48.00 before shipping. Free shipping requires $250 in orders, so multiple items or a larger peptide order would be needed to reach that threshold.

FAQ - Real Peptides Bacteriostatic Water

How many peptide vials can one bacteriostatic water vial reconstitute?

It depends on the amount of water that is used for the reconstitution process. It suffices to add 2 ml of water to each peptide vial, which means that one 10 ml bottle of bacteriostatic water will be sufficient for five reconstitutions. If you need only 1 ml in each vial, then one bottle will give ten applications. Make the changes according to the level of concentration required.

What is the difference between bacteriostatic water and sterile water?

Bacteriostatic water includes 0.9% benzyl alcohol, which acts as a preservative and prevents the growth of bacteria. Unlike sterile water, which has no preservative whatsoever and must be used in one session after opening, bacteriostatic water is the right option for multi-dose peptide vials to be drawn from for weeks.

Does bacteriostatic water expire?

As long as not yet opened, the shelf-life is indicated on the packaging. After the vial has been punctured, it is better to use it within 28 days. The benzyl alcohol used as a preservative is able to delay the development of microbiological contamination, but it does not assure sterility for an unlimited time. If the vial is not clear and has some particles in it, it is better to throw it away.

Can I use this with any lyophilized peptide?

For reconstituting research peptides like BPC-157 and TB-500, USP-grade bacteriostatic water containing 0.9% benzyl alcohol is normally the solvent used. It is essential to ensure that the solvent is compatible with the peptide prior to using it.
