Real Peptides Bacteriostatic Water Review
Real Peptides bacteriostatic water 10 ml reviewed. $4.80 per vial, USP-grade, 0.9% benzyl alcohol. Why you need it for reconstituting BPC-157 vials.
Key Features
- Volume: 10ml per vial
- Price: $4.80 (sale from $9.60)
- Grade: USP
- Preservative: 0.9% benzyl alcohol
- Packaging: Sealed glass vial
- Stock: 656 units available
- Shelf life after first puncture: 28 days
- Storage: Room temperature (20-25C), protect from light
At $4.80, this is a low-cost addition to any peptide order. Bundling it with a peptide purchase from the same vendor saves on separate shipping costs.
What's Inside
- Water: USP-grade sterile water
- Preservative: 0.9% benzyl alcohol
- Volume: 10ml
- Container: Glass vial with sealed stopper
There are no active research compounds in this product. It is strictly a solvent and diluent. The benzyl alcohol concentration at 0.9% is the industry standard for bacteriostatic applications. It is sufficient to prevent microbial growth between draws without interfering with most peptide assays. One 10ml vial can reconstitute multiple peptide vials depending on the dilution volume selected.

How to Store and Handle
Store unopened vials at room temperature between 20-25C. Keep them away from direct sunlight. Refrigeration is not required. After the first needle puncture, the benzyl alcohol preservative maintains sterility for up to 28 days, provided proper technique is followed.
Wipe the rubber stopper with an isopropyl alcohol pad before each draw. Use a fresh syringe every time to minimize contamination risk. When reconstituting a peptide vial, inject the bacteriostatic water slowly along the inner wall of the peptide container. Do not spray it directly onto the lyophilized cake. Allow the powder to dissolve on its own. Discard the bacteriostatic water vial after 28 days from first use or if the liquid appears cloudy, discolored, or contains visible particles.
Bacteriostatic Water by Real Peptides is a 10ml sealed glass vial priced at $4.80, marked down from $9.60. The product meets USP grade standards and contains 0.9% benzyl alcohol as a preservative. With 656 units currently in stock, availability is not a concern. We checked the listing details, verified the specifications, and compared this against the handful of competing bacteriostatic water products we track.
Overview
Bacteriostatic water is the standard solvent for reconstituting lyophilized peptides in a laboratory setting. The 0.9% benzyl alcohol concentration inhibits microbial growth, which allows the vial to be punctured multiple times over a period of days or weeks without the contamination risk that plain sterile water carries. This is a commodity product, but the differences between vendors come down to grade, packaging, and price.
Real Peptides packages this in a sealed glass vial rather than plastic. Glass is inert and does not leach compounds into the water, which matters when the solvent will be mixed with sensitive research materials. The USP designation means the product was manufactured according to United States Pharmacopeia specifications for purity and composition.
Our Verdict
We rated Real Peptides Bacteriostatic Water at 4.7 out of 5. Sub-scores: Testing 4.8, Purity 4.8, Labeling 4.5, Value 4.8. The value score is the standout because $4.80 for a USP-grade glass vial is genuinely inexpensive. The high stock count of 656 units means back-orders are unlikely.
There is not much to critique here. Bacteriostatic water is a straightforward product, and Real Peptides delivers it at the right grade, in the right packaging, at a fair price. For researchers already ordering peptides from Real Peptides, adding this to the cart is a no-brainer. One vial of bacteriostatic water at 1ml per reconstitution covers roughly 10 peptide vials, making it one of the most efficient ancillary purchases in the lab supply chain.
FAQ
What is bacteriostatic water used for?
It is used to reconstitute lyophilized (freeze-dried) peptides and other dry research compounds into solution. The 0.9% benzyl alcohol preservative allows the vial to be drawn from multiple times while inhibiting bacterial growth, unlike plain sterile water which is single-use only.
How long does the vial last after the first puncture?
The recommended shelf life after first use is 28 days. After that period, the preservative may no longer guarantee sterility. Always clean the stopper with alcohol and use a fresh syringe for each draw to maximize the usable window.
Does this need to be refrigerated?
No. Store at room temperature between 20-25C and protect from direct sunlight. Refrigeration is not necessary for bacteriostatic water. This is different from reconstituted peptide solutions, which do require refrigeration at 2-8C.
How many peptide vials can one bottle reconstitute?
That depends on the volume of water used per reconstitution. At a standard 1ml per peptide vial, a single 10ml bottle of bacteriostatic water can reconstitute approximately 10 vials. Using 2ml per vial cuts that to 5. Calculate based on your desired concentration.
Can I use regular sterile water instead?
Plain sterile water works for single-use draws where the entire solution is consumed immediately. However, without a preservative, an opened vial of sterile water is vulnerable to bacterial contamination. For multi-dose peptide vials that will be drawn from over days or weeks, bacteriostatic water is the appropriate choice.
