Answers on reconstitution, storage, ordering, shipping, lab testing and compliance.

Ordering & Shipping

We ship worldwide — Australia, the United States, United Kingdom, and most international destinations. All orders are dispatched from Sydney, Australia.

Australian orders ship express and typically arrive in 2–5 business days. Due to current high order volume, all orders are arriving within approximately 2 weeks of the order date. A tracking number is provided once your order ships.

Yes. Orders ship in plain, protective packaging with no product details visible on the outside.

Yes. A tracking number is emailed to you once your order is dispatched.

Products & Quality

Yes. Each batch is analysed by reversed-phase HPLC to verify purity before it is dispatched.

It means the HPLC main-peak area is 99% or higher — the target compound makes up over 99% of the material, with only trace impurities.

A COA is a document showing the analytical results — HPLC purity, mass-spectrometry identity, and LAL endotoxin screening — for a specific production lot. Where available, the COA is linked for download on the product page and reflects the batch you receive.

Bacteriostatic water contains 0.9% benzyl alcohol, which inhibits microbial growth and allows multiple withdrawals from a vial over roughly 28 days. Sterile water has no preservative and is intended for single use. See the full comparison on the Bacteriostatic Water product page.

Store lyophilised (powder) vials below 25°C, away from light and moisture. Refrigerate or freeze for long-term storage. Once reconstituted, keep refrigerated.

Lyophilised peptides are generally stable for 18–24 months when stored cold and dry. Once reconstituted, use within the stability window described below.

Reconstitution

Add your reconstitution water slowly down the inside wall of the vial onto the powder, then swirl gently — do not shake — until fully dissolved.

This depends on the concentration your protocol requires; 1–3 mL per vial is common. Choose a volume that makes your measurements convenient.

Reconstituted with bacteriostatic water and refrigerated, peptides are typically stable for around 28 days. Reconstituted with sterile water, use immediately.

Tap or distilled water is neither sterile nor preservative-protected and risks contamination and degradation of the compound. Use bacteriostatic or sterile water.
