Bacteriostatic Water is a sterile diluent containing 0.9% benzyl alcohol, used in laboratories for reconstituting lyophilized peptides. The preservative prevents bacterial growth, allowing multiple withdrawals from a single vial during controlled experiments. Researchers rely on bacteriostatic water for safe, precise, and contamination-free reconstitution of peptides like BPC-157, TB-500, and CJC-1295.

Store lyophilized peptides in a cool, dry place away from light. For longer‑term storage, refrigerate or freeze. Minimize freeze‑thaw cycles and follow your lab’s SOPs.

Peptide powders are lyophilised to maximise stability and shelf life. Correct reconstitution preserves activity and helps prevent degradation, aggregation, or contamination.

Let both the vial and bacteriostatic water reach room temperature (15–20 minutes). Disinfect stoppers with alcohol. Using a sterile syringe, add 1–3 mL of bacteriostatic water slowly down the vial wall (avoid spraying the powder). Swirl gently until fully dissolved—do not shake. Store at 2–8 °C. For exact volumes, use the Bluewell Peptide Calculator.

Bacteriostatic water is the standard (preservative extends usability). Sterile Water for Injection is suitable for immediate single‑use preparations. Dilute acetic acid may help with peptides that dissolve poorly in water.

• Freezer (‑20 °C): best for long‑term storage (up to 4 years).
• Fridge (2–8 °C): suitable for 12–24 months.
• Room temperature: only a few days; stability drops quickly.
• Keep sealed: protect from light, moisture, and temperature swings. Minimise freezer door openings.

Refrigerate at 2–8 °C. For longer horizons, aliquot into sterile vials and freeze to avoid repeated freeze–thaw. Use a suitable cryoprotectant (e.g., glycerol) if storing frozen for extended periods.

Typical refrigerated stability is 3–6 weeks. 4 weeks is a practical sweet spot; beyond that, activity may decline. Frozen aliquots with cryoprotectant can last several months. Always follow your lab’s SOPs.

Yes. We include clear guides with first orders and have step‑by‑step resources on our website, including our Peptide Calculator and Reconstitution Guide.

• Using tap or boiled water.
• Vigorous shaking or vortexing (can denature peptides).

We provide a Certificate of Analysis for every product and batch. You can view them anytime on our Lab Certificates page, or access them directly on each product page.

All of our peptides undergo HPLC and mass spectrometry testing as part of our quality program. Selected lots are also independently verified by accredited third‑party labs.

Vials are sealed and lot‑coded, then packed in protective materials to maintain integrity during transit. Temperature‑sensitive products ship with appropriate safeguards.

We follow controlled SOPs, verify identity and purity for each lot, and only release batches that meet our specification thresholds.

• Appearance after reconstitution: should be a clear solution; avoid persistent cloudiness or unexpected color.
• Dissolution behavior: powder should dissolve with gentle swirling; stubborn clumping can indicate insolubility or moisture exposure.
• Particulates: visible particles are a red flag; do not filter unless your protocol allows and sterility is maintained.
• pH / solvent sanity: ensure your diluent and target pH match the protocol; extreme pH can degrade peptides.
• Documentation match: vial lot number should match the COA; verify sequence and mass data.
• Model response: unexpected irritation in test systems can signal impurities or incorrect solvent. Review method and materials before proceeding.

These checks complement—not replace—formal analytical testing.

Purity is the proportion of intended peptide vs. by‑products. Yield is how much peptide is obtained from synthesis. We prioritize high, batch‑consistent purity first, then yield.
