Research peptides for New Zealand laboratories

New Zealand's research peptide demand is driven by the country's strong academic life-sciences base across the University of Auckland, University of Otago, Victoria University of Wellington and the Crown Research Institutes, plus a growing private biotech sector. Domestic supply of specialist research peptides is extremely limited, so most NZ labs source from Australian or international research suppliers.

Peptx ships directly to New Zealand research addresses via tracked DHL Express, cutting out the typical reseller markup chain. Compounds are sourced from vetted factories (independent lab testing). Recent independent laboratory results are published in the COA Library.

Prices are shown in GBP; your bank or card provider handles any conversion.

Peptx ships to research and laboratory addresses across New Zealand via tracked DHL Express. Standard transit is 7 to 12 business days from dispatch, with Auckland, Wellington and Christchurch on the faster end of that range. All packages clear NZ Customs as research reagents.

Packages ship in plain, unbranded outer packaging with desiccant to maintain lyophilised powder stability through extended transit.

• 7 to 12 business day delivery New Zealand-wide
• Tracked via DHL Express with end-to-end visibility
• Cleared as research reagent for laboratory use
• Plain, unbranded outer packaging

Peptx stock is backed by independent laboratory results, at typically 99%+ purity (HPLC); the guaranteed minimum varies by compound. Our suppliers are not chosen on a single rating. We weigh independent lab testing.

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 one of the labs on our testing page (/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, raised within 14 days of delivery, is reviewed under our Purity Guarantee and, where verified, refunded or re-shipped.

All compounds are supplied as sterile lyophilised powder in sealed vials, packed with desiccant, and stored at controlled temperature throughout the supply chain.
