Research peptides for New Zealand laboratories
Peptx supplies research-grade peptides to New Zealand universities, biotech laboratories and research groups. 220+ compounds including Retatrutide, Tirzepatide, Semaglutide, BPC-157 and TB-500, all at manufacturer-stated 99%+ purity, with tracked international shipping and transparent USD pricing. Strictly for in-vitro laboratory research, not for human or animal consumption.
New Zealand research peptide market
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 ISO 17025 lab testing), HPLC and Mass Spectrometry tested at the manufacturer (documentation not shipped with orders); certificates published in the COA Library where available.
Prices display in USD with optional NZD or AUD conversion, refreshed weekly against mid-market FX rates.

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.

New Zealand FAQ
Are research peptides legal to import into New Zealand?
Research peptides not classified as controlled drugs under the Misuse of Drugs Act 1975 can lawfully be imported as research reagents for in-vitro laboratory work. They are not approved by Medsafe for human use. All products supplied by Peptx are strictly for in-vitro laboratory research and are NOT for human or animal consumption.
How long does New Zealand delivery take?
7 to 12 business days from dispatch via tracked DHL Express. Customs clearance typically completes within 24 to 48 hours of arrival at the NZ border for research reagent shipments.
Do I pay customs duty or GST?
GST is generally applied to imported goods over the NZD 1000 threshold at the point of clearance. There is typically no customs duty on research peptides. Many academic and biotech buyers reclaim GST as a business input.
Can I pay in NZD?
Prices display in NZD with checkout in USD at the live mid-market FX rate. AUD display is also available.
What is the minimum order?
One box per dose, typically 10 vials for injectable peptides or 3 tubs for capsule formats.
