Ensure the integrity and longevity of your research peptides with Peptide Hubs' premium Bacteriostatic Water. This sterile, pyrogen-free solution contains 0.9% benzyl alcohol as a preservative, specifically formulated for the reconstitution and preservation of lyophilized peptides. Our Bacteriostatic Water meets USP (United States Pharmacopeia) standards, guaranteeing the highest quality for your research needs.
Bacteriostatic Water is not simply sterile water—it's a carefully engineered solution designed to maintain peptide stability while preventing microbial growth. The 0.9% benzyl alcohol concentration is specifically calibrated to inhibit bacterial growth without compromising peptide integrity. This concentration has been established through extensive research as the optimal balance between antimicrobial efficacy and peptide compatibility.
According to guidelines from the United States Pharmacopeia, bacteriostatic water containing 0.9% benzyl alcohol is the recommended diluent for multi-dose parenteral preparations. The benzyl alcohol acts through multiple mechanisms: disrupting microbial cell membranes, inhibiting enzyme systems, and preventing the growth of bacteria, fungi, and other microorganisms that could degrade your valuable peptides.
Prevents bacterial and fungal contamination in reconstituted peptides, ensuring product stability and safety.
Allows reconstituted peptides to maintain potency for 4-6 weeks when properly refrigerated.
Specifically formulated to maintain peptide stability without degrading molecular structure.
Enables accurate dosing through consistent dilution ratios and maintained sterility.
For optimal peptide research results, pair with our Ultra-Fine Insulin Syringes which allow for precise measurement and administration of reconstituted peptides.
Always follow aseptic technique when reconstituting peptides. Clean the rubber stopper of both the peptide vial and bacteriostatic water with alcohol swabs. Draw 1-2 mL of bacteriostatic water into a sterile syringe, then slowly inject it into the peptide vial, aiming the stream against the glass wall to minimize foaming. Gently swirl the vial until the peptide is completely dissolved—do not shake vigorously. Store reconstituted peptides in the refrigerator and use within 4-6 weeks for optimal potency.
Peptide Type | Recommended Volume | Storage After Reconstitution | Stability Period |
---|---|---|---|
Growth Hormone Releasing Peptides (GHRPs) | 1-2 mL | Refrigerated (36-46°F) | 4-6 weeks |
Growth Hormone Releasing Hormones (GHRHs) | 1-2 mL | Refrigerated (36-46°F) | 4-6 weeks |
Healing Peptides (BPC-157, TB-500) | 2-3 mL | Refrigerated (36-46°F) | 4-6 weeks |
Metabolic Peptides (MT2, PT-141) | 1-2 mL | Refrigerated (36-46°F) | 4-6 weeks |
Important: This product is intended for research purposes only. Not for human consumption. Always follow proper sterile technique when handling and storing bacteriostatic water and reconstituted peptides.
Our Bacteriostatic Water undergoes rigorous quality control testing to ensure sterility, pyrogen-free status, and precise benzyl alcohol concentration. Each batch is manufactured in ISO-certified facilities using pharmaceutical-grade ingredients and advanced filtration technology. The result is a premium diluent product that maintains the integrity of your research peptides while preventing microbial contamination.
Peptide Hubs remains committed to providing the highest quality research materials to the scientific community. Our Bacteriostatic Water represents an essential component of proper peptide research methodology, ensuring that your valuable compounds remain stable, sterile, and effective throughout your research timeline.
The key difference is the presence of benzyl alcohol as a preservative. Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits microbial growth and allows reconstituted peptides to be used multiple times over 4-6 weeks when refrigerated. Sterile water has no preservatives and is intended for single-use applications only, as it provides no protection against bacterial growth once opened. For peptide research, bacteriostatic water is generally preferred as it extends the usable life of reconstituted peptides.
An unopened vial of bacteriostatic water typically has a shelf life of 1-2 years when stored at room temperature away from direct light. Once the rubber stopper has been punctured, the vial should be used within 28 days for optimal preservative efficacy, even if refrigerated. The benzyl alcohol concentration gradually decreases after opening, reducing its effectiveness against microbial growth over time. Always mark the date of first use on the vial.
Bacteriostatic water is suitable for most research peptides, but there are exceptions. The majority of growth hormone releasing peptides (GHRPs), growth hormone releasing hormones (GHRHs), and healing peptides are compatible with bacteriostatic water. However, some particularly fragile peptides or those with specific molecular structures may require alternative reconstitution solutions. Always consult the specific storage requirements for each peptide compound. For peptides known to be sensitive to benzyl alcohol, sterile water without preservatives may be recommended for immediate single-use applications.
Unopened bacteriostatic water should be stored at room temperature (68-77°F) away from direct light. After opening, it can be stored at room temperature or refrigerated, but should be used within 28 days. Reconstituted peptides should always be refrigerated (36-46°F) and protected from light. Avoid freezing reconstituted peptides unless specifically indicated, as freeze-thaw cycles can degrade peptide structure. Never expose peptides to excessive heat or direct sunlight, as this can rapidly degrade their molecular integrity.
The 0.9% concentration represents the optimal balance between antimicrobial efficacy and peptide compatibility established through extensive pharmaceutical research. This concentration is sufficient to inhibit microbial growth (bacteria, fungi, and other contaminants) while being low enough to avoid potential interactions with peptide structures. Higher concentrations could potentially affect peptide stability or cause precipitation, while lower concentrations might not provide adequate protection against microbial contamination. This 0.9% standard is consistent with USP guidelines for bacteriostatic water for injection.
