Bacteriostatic Water
Buy More, Save More
Bacteriostatic Water is a sterile, nonpyrogenic solution containing 0.9% (9 mg/mL) benzyl alcohol as a bacteriostatic preservative.
Formulated specifically for peptide research, this Bacteriostatic Water prevents bacterial growth, reducing the risk of contamination that could interfere with research.
Supplied in a multi-dose vial with a self healing cap for repeated withdrawals to reconstitute peptides. Its pH ranges from 6.0 to .80
Ideally stored, this product remains effective for 28 days after opening. For best efficacy, store in a dark environment between 20 to 25°C (68 to 77°F) to preserve its quality.
Everything you need alongside your peptides.
From order to research in four simple steps.
Choose from 30+ research peptides, all independently tested at 99%+ purity. Select your quantity and checkout securely.
Orders placed before 2pm are dispatched same day via Royal Mail Tracked 24 in discreet packaging.
Dissolve the lyophilised powder with bacteriostatic water following our reconstitution guide. Store at 2–8°C for up to 6 weeks.
Every product has a Certificate of Analysis. Use our dosage calculator and educational guides to support your research protocols.
Every batch manufactured to pharmaceutical-grade standards with a minimum 99% purity verified by independent third-party HPLC analysis.
Independent laboratory testing via HPLC and mass spectrometry confirms identity and purity. No in-house-only testing — fully transparent.
Certificates of analysis available for every product. Full batch documentation available online for verification before you buy.

Everything you need to get the most from your peptides.
Every batch is independently tested by a third-party laboratory using HPLC (High-Performance Liquid Chromatography) and mass spectrometry. Our peptides consistently achieve ≥99% purity. Full Certificates of Analysis are available for every product.
Reconstitute with bacteriostatic water by slowly adding it down the inner wall of the vial, then gently swirling (never shaking). For step-by-step instructions with video, see our Reconstitution Guide. Use the Dosage Calculator to determine the correct volume.
Every order includes the lyophilised vial(s). You will need to add bacteriostatic water and any accessories necessary. Check out our bundles that include accessories.
Store lyophilised (unopened) peptides at -20°C for long-term storage or 2–8°C if reconstituting within a few weeks. Once reconstituted with bacteriostatic water, store at 2–8°C and use within 4–6 weeks. Keep away from direct light and avoid freeze-thaw cycles. See our storage guide for more detail. See product pages for peptide specific storage recommendations.
