Research peptides delivered across Australia
Peptx supplies research-grade peptides to Australian laboratories, universities and group-buy collectives. Over 220 compounds in stock, manufacturer-stated 99%+ purity, tracked international shipping to every Australian state, and transparent pricing that converts to AUD live.
The Australian research peptide market
Australia has one of the most active research peptide communities outside of Europe and North America, driven by strong university research programmes in Sydney, Melbourne and Brisbane, plus a sizeable independent group-buy network. Demand for GLP-1 receptor agonists like Retatrutide, Tirzepatide and Semaglutide has accelerated sharply over the last 24 months.
Local Australian suppliers exist but typically run small catalogues at 2X to 4X our pricing because they buy through multiple distribution layers. Peptx ships directly from factory-aligned fulfilment so Australian researchers get the same wholesale economics as US and EU buyers.
Prices on this site can be displayed in AUD, USD or GBP, refreshed weekly against mid-market FX rates so what you see is what you pay.

Independent purity verification
Peptx stock is backed by manufacturer HPLC and Mass Spectrometry data plus independent spot checks, at typically 99%+ purity (HPLC); the guaranteed minimum varies by compound. Our suppliers are not chosen on a single rating. We weigh independent testing at accredited ISO 17025 labs.
Independent laboratories test our material on a rolling programme: random quality-control checks, tests on stock we buy in, and testing as part of vetting every new supplier. Certificates are published openly in the COA Library rather than issued per order, so you can read the laboratory's report before ordering, not after. Independent verification is expanding across the catalogue, with further tests in progress across September and October. If you want your specific batch independently checked, send a sample to an accredited ISO 17025 lab (see our Recommended Labs at /testing): a result you commission yourself carries more weight than one handed to you by a seller. Any independent lab result below the product's stated guaranteed minimum purity, or a sealed-vial endotoxin or sterility failure, is refunded or re-shipped within 14 days.
All compounds are supplied as sterile lyophilised powder in sealed vials, packed with desiccant, and stored at controlled temperature throughout the supply chain.

Independent retesting is encouraged; a 14-day refund window applies to any independently verified result below the product's stated guaranteed minimum purity.
Discreet, tracked shipping
Plain unbranded packaging with no external product references. Full tracking from dispatch to delivery.
Bulk research MOQs
Minimum order quantity is one box (10 vials or 3 tubs depending on format). Designed for laboratories and group buys, not individual consumers.
Australia FAQ
Is it legal to import research peptides into Australia?
Most research peptides we supply are not scheduled substances and can be lawfully imported for in-vitro laboratory research. Buyers are responsible for confirming the regulatory status of any specific compound in their state. All products supplied by Peptx are strictly for in-vitro laboratory research and are NOT for human or animal consumption.
Will my shipment clear Australian customs?
Yes in the vast majority of cases. Peptx pre-completes all customs paperwork with appropriate HS codes for laboratory reagents. We have not had a tracked shipment fail to clear in normal operating conditions.
How long does shipping to Australia take?
Typical transit is 7 to 12 business days from dispatch. Orders to Sydney, Melbourne and Brisbane usually arrive in the lower end of that range; Perth and remote areas closer to 12 days.
Can I pay in AUD?
Prices display in AUD when you select it in the currency switcher. Checkout charges in USD with the live converted AUD equivalent shown at the point of payment.
Do you ship to PO boxes?
We ship to a verified street address for laboratory or research delivery. PO box delivery is not supported because tracked international courier requires signature on delivery.
