What's Inside

Inside the vial is 10ml of sterile water containing 0.9% benzyl alcohol. USP grade means the product satisfies United States Pharmacopeia criteria regarding purity, composition, and manufacturing quality. Benzyl alcohol at this concentration prevents the growth of microorganisms while allowing for the results of various peptide assays to remain unaffected.

The glass bottle is inactive and it does not release chemicals into the water. The aluminum crimp closure holds a rubber plug in position, allowing needle entry while preserving the integrity of the bottle through the sampling process.

How to Store and Handle

Keep the vials in unused condition inside at room temperature, protected from sunlight. No refrigeration is necessary. After the first needle puncture, the preservative benzyl alcohol makes it possible to extract through the needle many times during 28 days. After that period, throw away the vial.

Prior to each use, we recommend that you clean the rubber stopper with isopropyl alcohol. In addition, always use a new syringe. When adding water during the peptide reconstitution process, inject it at an angle so that it runs down the wall of the peptide vial without shaking the peptide powder. If the water looks cloudy or discolored or contains any particles, make sure to discard it as soon as possible.

Real Peptides Bacteriostatic Water is a 10ml vial of sterile, USP-grade water with 0.9% benzyl alcohol as a preservative, costing $4.80. It is the standard solvent for the reconstitution of lyophilized peptide vials. This product is not important for encapsulation. However, researchers using BPC-157 vials will require it. Below we review the specifications, packaging, and practical aspects of the product.

Overview

Bacteriostatic water does have a special distinction from sterile water: Sterile water contains no preservatives and is intended for single use. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits bacterial growth, enabling multi-dose use from one vial for up to 28 days. Bacteriostatic water is also appropriate for any type of multi–dose peptide vials.

The product is identified by SKU RP-BAC10V and is shipped together with peptide orders from Real Peptides' warehouses in Florida and California. Bacteriostatic water is not needed if you order BPC-157 capsules. The capsules are ingested in an unchanged form.

Our Verdict

Real Peptides Bacteriostatic Water can be bought at a price of $4.80 for a vial of 10mls, which makes it a mere commodity product. It follows the standard USP requirements and comes in glass packaging while its benzyl alcohol concentration is at the normal 0.9%.

Each 10ml vial contains sufficient solvent to be used in the reconstitution of several peptide vials, depending on how much solvent is used for each reconstitution. For example, if 1ml is added to a 10mg peptide vial, this creates a 10mg/ml solution and 9ml of solvent remains. Researchers who wish to purchase the Real Peptides BPC-157 10mg vial should request it at the same time as their peptide order to reduce shipping fees.

FAQ

Do I need bacteriostatic water for BPC-157 capsules?

No. Capsules are oral forms that do not require reconstitution. Bacteriostatic water is only required for lyophilized vials that are required to be dissolved before being used.

How long does bacteriostatic water last after opening?

For a maximum of 28 days. The preservative benzyl alcohol functions to suppress bacterial growth for this duration. Subsequent to 28 days, dispose of the vial even if there are still contents left.

Can I use regular sterile water instead?

Sterile water can be used for one-time draws where the complete solution will be consumed right away. In the case of multiple-draw vials, the requirement for bacteriostatic water arises as this kind of water holds preservatives which will help prevent the growth of microorganisms between draws.
