New Zealand's Research Peptide Supplier
Stock held in New Zealand, batch-tested by an independent lab, and dispatched same day — every vial traceable back to its own Certificate of Analysis.
WHY NZ PEPS EXISTS
A local answer to a slow, opaque market.
Before NZ Peps, Kiwi researchers were stuck choosing between overseas sellers with unpredictable customs timelines and vague paperwork, or paying inflated reagent-catalogue prices for compounds that arrived with no batch-level documentation at all. We started NZ Peps to close that gap: peptides held in New Zealand, priced in NZD, and backed by a Certificate of Analysis you can actually check.
Every vial we dispatch is tied to a batch number that resolves to a public COA. Nothing ships without its chromatogram on file, and nothing leaves our Auckland dispatch point without CourierPost tracking attached.

HOW WE OPERATE
Four things we won't compromise on.
Verified, not claimed
Purity figures come from independent third-party HPLC-MS reports, never from a supplier datasheet we can't check ourselves.
A COA per batch
Every batch code on the label maps to a downloadable Certificate of Analysis. If the numbers don't line up, the vial doesn't ship.
Local accountability
New Zealand stock, a New Zealand support inbox, New Zealand bank accounts. Any issue is resolved here, not offshore.
Fast NZ-wide dispatch
Orders paid before 2pm NZST are picked, packed and lodged with CourierPost the same day, tracked door to door.
THE TESTING WORKFLOW
From contract lab to your bench.
Every production run is split prior to lyophilisation. A sample goes to an independent analytical lab for reverse-phase HPLC and LC-MS confirmation, while the remainder sits in quarantine until the results clear our 99% purity floor. Anything short of spec is rejected outright — not relabelled, not blended into another lot.
Cleared batches are filled, sealed under nitrogen, and logged into our Lab Results portal with a batch number, assay date and the full report attached, so you can cross-check any vial we send you.
What every release file includes
- Reverse-phase HPLC chromatogram
- LC-MS mass confirmation
- Net peptide content & purity %
- Batch ID, fill date, lot size
- Storage instructions for lyophilised stock
FULFILMENT
Dispatched from inside New Zealand.
Orders are picked, packed and lodged with NZ Post CourierPost from our New Zealand dispatch point — no customs holds, no international relays, no surprise duties. Auckland, Wellington and Christchurch typically see next-business-day delivery; rural addresses add roughly one extra business day.
