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 with tracking, 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.

Factory Direct kits ship to New Zealand direct from our manufacturing partner, dispatched within 48 hours. Delivery usually takes 11 days or more, and tracking is emailed as soon as it is available.

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.
