Frequently Asked Questions

We currently ship within Australia only via Australia Post. All orders include tracking. We ship to all Australian states and territories including NSW, VIC, QLD, SA, WA, TAS, NT, and ACT.

Orders are dispatched next business day for all orders placed before 11PM AEST. Pre-order items are dispatched within 7–10 business days. Once dispatched, you will receive an Australia Post tracking number via email.

Yes — free shipping on all orders over $199 AUD. Orders under $199: Standard Post $11.99 (2–6 business days, tracked) or Express Post $15.99 (1–3 business days, priority tracked). All orders ship via Australia Post with full tracking.

We accept PayID (zero fees), Bank Transfer (zero fees), Credit/Debit Card via Stripe, and PayPal. PayID and Bank Transfer are the most cost-effective options as they attract zero processing fees. Card and PayPal payments may include a small processing fee.

Yes. All orders are dispatched with Australia Post tracking. You will receive a tracking number via email once your order has been dispatched. You can track your parcel at auspost.com.au.

Due to the nature of research chemicals, we do not accept returns on opened products. If your order arrives damaged or incorrect, please contact us within 48 hours at info@auspeptidewarehouse.com.au and we will arrange a replacement. All claims require photographic evidence.

All orders are shipped in discreet, plain sealed envelopes with no branding visible on the outside. This ensures privacy and protects the integrity of the product during transit.

Yes — for research institutions and laboratories requiring larger quantities, please contact us at info@auspeptidewarehouse.com.au for wholesale pricing and availability.

All peptides are ≥99% pure as measured by HPLC (High-Performance Liquid Chromatography). Our minimum accepted purity for any product is 99.0%. Many products exceed this at 99.1%, 99.2%, 99.3%, or higher.

Yes. Every batch comes with a Certificate of Analysis (COA) from an independent, accredited third-party laboratory. The COA includes: HPLC chromatogram, purity %, mass spectrometry identity confirmation, batch number, sterility results, and LAL endotoxin assay data (<1.0 EU/mg). All COAs are available in our COA Library.

High-Performance Liquid Chromatography (HPLC) is the gold standard analytical technique for determining peptide purity. It separates the components of a sample under high pressure through a chromatography column. The resulting chromatogram shows the relative percentage of each component — the target peptide peak versus any impurities. A 99%+ HPLC result means at least 99% of the detected material is the target compound.

Yes. All quality testing is performed by independent, accredited third-party laboratories — not in-house. This eliminates conflicts of interest and ensures that purity results are objective and traceable. We do not dispatch any batch that fails quality criteria.

The LAL (Limulus Amebocyte Lysate) assay is used to detect bacterial endotoxins in the product. Endotoxins can interfere with research results and indicate bacterial contamination. Our standard is <1.0 EU/mg. All batches are LAL tested before dispatch.

Yes. All batches undergo sterility screening as part of our quality control process. Only batches that pass sterility testing are approved for dispatch.

All peptides are sourced from GMP (Good Manufacturing Practice) certified manufacturing facilities. Full chain-of-custody documentation is maintained from synthesis through to our Melbourne warehouse. We do not source from uncertified suppliers.

GMP (Good Manufacturing Practice) certification means a facility meets internationally recognised standards for the production, testing, and quality control of pharmaceutical and research-grade compounds. GMP facilities have documented procedures, equipment validation, staff training requirements, and audit trails.

All peptides sold by Peptide Warehouse Australia are strictly for laboratory and in-vitro research use only. They are not intended for human consumption, therapeutic use, or veterinary application. Safety data for human use has not been established for most research peptides. All research should be conducted in accordance with applicable ethical and regulatory standards.

Yes. Research peptides are legal to purchase and possess in Australia for legitimate in-vitro laboratory and research purposes. Most synthetic research peptides are not listed as scheduled substances under the Poisons Standard (SUSMP) when sold for research use only. Purchasers must be 18+ and confirm research-only use. For specific legal questions, consult a qualified Australian legal professional.

Lyophilised (freeze-dried) peptides should be stored at −20°C for long-term stability (12–24 months). Once reconstituted with bacteriostatic water, store at 2–8°C and use within 4 weeks. Protect from light, moisture, and repeated freeze-thaw cycles. NAD+ is particularly moisture-sensitive — store desiccated.

Use bacteriostatic water (BAC water) as the standard diluent. Draw the desired volume with a clean 29G insulin syringe. Inject slowly into the peptide vial down the side of the glass — do not aim directly at the powder cake. Gently swirl to dissolve — do not shake or vortex. The resulting solution should be clear. Label with compound name, concentration, and date. Store at 2–8°C.

The reconstitution volume depends on your desired working concentration. Common ratios: 1mL into 10mg = 10mg/mL; 2mL into 10mg = 5mg/mL. One 10mL vial of BAC water is sufficient for multiple peptide reconstitutions. See our Reconstitution Guide blog post for a full concentration table.

Yes — we stock pharmaceutical-grade BAC Water 10mL and sterile 29G insulin needles in our Supplies category. These are also available as part of our Retatrutide Research Bundle for convenience.

Lyophilised (freeze-dried) peptides are the most stable form, with a shelf life of 12–24 months at −20°C. Liquid/pre-mixed peptides are less stable and degrade faster. We supply all peptides in lyophilised format for maximum stability and shelf life.

There is no minimum order. You can order a single product. Free shipping applies on orders over $199 AUD. For bulk or wholesale enquiries, contact us at info@auspeptidewarehouse.com.au.
