KIWI-OWNED · STOCKED IN NEW ZEALAND
Research peptides sourced, tested and shipped inside New Zealand
New Zealand Peptides exists because buying research compounds here used to mean gambling on an offshore parcel, an unverifiable COA and a month of waiting. We hold inventory locally, assay every lot by independent HPLC-MS, and hand parcels to NZ Post Courier the same business day your payment clears. From Retatrutide and Tirzepatide through to BPC-157, GHK-Cu, Cagrilintide and TB-500, every vial is lyophilised, nitrogen-sealed and traceable to a published certificate.

WHY RESEARCHERS SWITCH TO US
Four things an NZ supplier should get right
No import gamble, no mystery purity, no surcharge at the last step, no silence when you email.
Local stock, same-day dispatch
Everything listed is physically in New Zealand. Payment cleared by 2pm NZST leaves that afternoon with NZ Post Courier tracking sent straight to your inbox.
Purity you can actually check
Independent HPLC-MS on every lot with a release floor above 99%. The certificate is published against the batch ID before the vial is listed for sale.
Transparent NZD pricing
Prices are in NZD, GST-inclusive where applicable, with no card-processor surcharge and no minimum order. Bank transfer clears in minutes.
Cold-chain aware packing
Lyophilised under nitrogen, foil-wrapped, and shipped with insulated gel packs for temperature-sensitive compounds — included, not an upsell.
VERIFIED CUSTOMER FEEDBACK
Rated 4.9 out of 5 by New Zealand researchers
"Ordered at 11am on a Tuesday from Christchurch, courier dropped it Wednesday morning. COA matched the lot number on the vial exactly — that alone puts them ahead of everyone I'd used before."
"Retatrutide availability in NZ used to mean waiting on an offshore parcel and hoping. Having local stock with published mass-spec data has genuinely changed how we schedule work."
"Bank transfer cleared in about four minutes and the dispatch email came the same afternoon. No surcharge, no card nonsense, no chasing anyone for tracking."
Supplied for laboratory research only
Compounds sold by New Zealand Peptides are intended for in-vitro and laboratory research within New Zealand. They are not medicines, therapeutic goods or supplements, and are not for human or veterinary use.
BATCH-LEVEL TRANSPARENCY
One certificate per lot — not one per product page
A single generic COA reused across years of stock tells you nothing. Every batch we receive — Retatrutide, Tirzepatide, BPC-157, GHK-Cu and the rest — is sampled on arrival in New Zealand, sent for independent HPLC-MS identity and purity confirmation, given a traceable lot reference, and published in our open batch register before a single vial is sold.

BEFORE YOU ORDER
New Zealand Peptides questions, answered
Is New Zealand Peptides actually based in New Zealand?+
Yes. New Zealand Peptides Ltd is a Kiwi-owned company holding physical stock in New Zealand. Nothing is drop-shipped from offshore, so there is no border clearance step, no customs limbo and no three-week wait — your vials are already on a shelf here when you click order.
Why does Retatrutide lead your bestseller lineup?+
Retatrutide is the triple-agonist (GLP-1 / GIP / glucagon) reference compound that New Zealand research groups request more than anything else in our catalogue. We carry it in 10mg, 20mg and 30mg presentations, HPLC-MS verified above 99%, with the deepest local Retatrutide inventory available in NZ.
How quickly does an order reach my bench?+
Payment cleared before 2pm NZST on a business day means your parcel leaves the same afternoon on NZ Post Courier with tracking. Auckland, Hamilton, Wellington and Christchurch addresses typically receive next business day; rural delivery adds one to two days.
What does shipping cost in New Zealand?+
Orders over NZ$100 ship free nationwide, North and South Island. Below that a flat tracked-courier rate applies and is shown before you pay — nothing is added at the last screen. Rural delivery is included in the free threshold.
How do I pay, and are there surcharges?+
New Zealand bank transfer (online banking) settles within minutes and is our most-used method. Crypto (BTC, USDT) is available for overseas research groups. We add zero card-processor surcharges and there is no minimum spend.
Can I see the purity data before I buy?+
Yes — every lot is independently HPLC-MS assayed and the certificate is published openly on our Lab Results page against the batch ID printed on the vial. Check the paperwork first, then order.
Is the packaging discreet?+
Every parcel ships in plain, unbranded outer packaging with no compound names, no logos and a generic sender line. Cold-sensitive compounds travel with insulated gel packs at no extra charge.
