Express Shipping Only
Every order ships via Australia Post Express with tracking — no other shipping methods are offered. Secure, professional packaging and same-day dispatch keep transit time to a minimum.
Shipping Method
All orders are shipped exclusively via Australia Post Express. No other shipping methods are offered.
Delivery is typically 1–3 business days from dispatch via Australia Post Express. WA, SA, TAS, NT and regional areas can take longer.
Delivery times are estimates from the dispatch date and may vary depending on location.
Dispatch Schedule
Orders placed Monday–Friday before 12pm AEST are dispatched the same day. Orders after 12pm ship the next business day, and weekend orders ship Monday morning. Public holidays ship the next business day.
Dispatch begins once payment is cleared — instant for card and wallet payments; bank transfer and crypto can add around one business day.
Packaging
3.1 Secure Packaging
All orders are packaged using professional, laboratory-appropriate packaging to maintain product integrity during transit.
3.2 Temperature-Sensitive Products
Where required, temperature-sensitive materials are packaged using appropriate protective measures to help maintain integrity during transit. Express dispatch is used to minimise transit time.
Delivery Areas
We ship to all Australian states and territories. Express Post transit estimates from our dispatch facility:
Metro/CBD figures; regional addresses within each state run longer. International shipping is not offered.
Pre-Orders & Mixed Orders
Pre-order items are clearly marked and typically ship within 1–2 weeks.
If an order contains both in-stock and pre-order items, the full order will be dispatched together once all items are available.
Need in-stock items sooner?If you require in-stock items urgently, we recommend placing separate orders so they are not held back by pre-order items.
Order Tracking
All Australia Post Express shipments include tracking. Tracking details are provided via email once your order has been dispatched.
Delivery Instructions
During checkout, you can choose from two delivery handling options:
The carrier is authorised to leave your parcel at the delivery address (e.g. front door, porch) without a signature. This is the default option and applies unless you add Signature on Delivery.
Adds a small fee of $4.95 (free on orders over $350). The carrier must obtain a signature from a person at the delivery address before releasing the parcel.
Authority to Leave disclaimerBy proceeding with Authority to Leave (the default), you accept full responsibility for the parcel once it has been delivered to your address. PeptideX is not liable for any loss, theft, or damage to parcels left unattended. Your acceptance is recorded with your order as proof of consent. If you are concerned about parcel security, we strongly recommend adding Signature on Delivery at checkout.
Signature on Delivery
For added security, you can add Signature on Delivery at checkout for a small additional fee of $4.95. Orders over $350 include Signature on Delivery automatically at no extra cost. This requires the carrier to obtain a signature from a person at the delivery address before releasing the parcel.
Why choose Signature on Delivery?
- Provides proof your parcel was received by a person
- Prevents the carrier from leaving parcels unattended
- Strongest protection against lost or stolen parcels
What happens if no one is home?
The carrier will leave a notification card and your parcel will be held at the nearest Australia Post office for collection. You can collect it using your tracking number and valid ID.
Recommended for all ordersWe strongly recommend Signature on Delivery if you are concerned about parcel security. Without it, PeptideX is not obligated to investigate or resolve claims for parcels that tracking shows as delivered.
Lost or Missing Parcels
What to do if your parcel has not arrived or you believe it is missing:
If you used Authority to Leave (default): You accepted responsibility for the parcel once delivered. Check around your property, with neighbours, and in any safe spots. PeptideX is not liable for parcels left unattended per your authorisation.
If you selected Signature on Delivery: Check your tracking for the signature record. If no valid signature was obtained, please lodge a formal investigation with Australia Post directly. PeptideX will work with you toward a resolution if the carrier confirms a fault.
If your tracking has not updated for an extended period and the parcel does not show as delivered, please contact us within 14 days of the estimated delivery date. We will lodge an investigation with Australia Post on your behalf. If the carrier confirms the parcel is lost, store credit equal to the order value will be applied to your PeptideX account.
