All of our peptides are ≥99% purity, independently verified by third-party laboratories. Lab reports are added to product pages as they become available, and you can email us for a copy at any time.

Store unreconstituted (lyophilised) peptides at -20°C (freezer) for long-term storage, or 2–8°C (fridge) for short-term use within 1–3 months. Once reconstituted with BAC water, always refrigerate at 2–8°C and use within 30 days. Never freeze a reconstituted peptide. Avoid repeated freeze-thaw cycles.

Lyophilised peptides stored at -20°C are stable for 12–24 months depending on the specific compound. At 2–8°C (refrigerator), most peptides are stable for 3–6 months. At room temperature, stability is limited to short transit periods only (3–5 days).

Once reconstituted with bacteriostatic water, use within 28–30 days when stored at 2–8°C. The benzyl alcohol preservative in BAC water provides antimicrobial protection, but this degrades over time. If reconstituted with sterile water (no preservative), use within 24–48 hours.

BAC water is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. It's the standard solvent for reconstituting lyophilised peptide powders. The preservative prevents bacterial growth, allowing the vial to be used for multiple draws over up to 28 days after first puncture.

Add bacteriostatic water slowly against the inside wall of the vial — never directly onto the powder. Gently swirl until dissolved. Never shake. Refrigerate immediately after reconstitution. For detailed instructions with BAC water volumes specific to each peptide, see our Reconstitution Guide.
