Kiwi Peps — research peptides NZ, verified batch by batch
WHAT KIWI PEPS DOES
A New Zealand peptide supplier that shows its working
Most of the research peptides New Zealand labs can buy arrive from offshore with a generic certificate attached and no way to trace the lot. Kiwi Peps works the other way around. Stock sits here in New Zealand. Each lot — Retatrutide, Tirzepatide, Semaglutide, BPC-157, GHK-Cu, MOTS-C, CJC-1295/Ipamorelin and the rest — is sampled, independently HPLC-MS verified, and published in The Batch Book before a single vial goes out. Priced in NZD, paid by bank transfer, couriered tracked from Auckland to Invercargill.

WHY KIWI PEPS
Six reasons NZ researchers switch their supply here
Local stock, local testing, local courier. No customs queue, no mystery lot numbers, no card processor skimming the order.
Bench-Ready Dispatch
Transfer cleared by 2pm NZT and your parcel is scanned into CourierPost that afternoon with tracking emailed straight through.
The KP-99 Purity Standard
Independent HPLC-MS on every lot. Anything reading under 99% is quarantined and never listed — no exceptions, no quiet substitutions.
No surcharges, ever
Straight New Zealand bank transfer from ANZ, ASB, BNZ, Westpac or Kiwibank. What the cart says is what leaves your account.
Stock that is actually here
Vials sit in our New Zealand facility, not a warehouse offshore. Nothing you order is waiting on a border clearance or an international relabel.
Lyophilised and nitrogen sealed
Freeze-dried, capped under inert nitrogen and stored cold, so the material you reconstitute behaves the same way the certificate says it should.
Support that reads the COA
Email support@kiwipeps.co.nz and a New Zealander who knows the compound, the lot history and the courier run answers you.
CHECKOUT

THE BATCH BOOK
Every lot Kiwi Peps ships has a certificate you can read first
One generic certificate per product, uploaded once and never touched again, tells you nothing about the vial in your hand. So we keep The Batch Book instead: each new lot of Retatrutide, BPC-157, GHK-Cu, Semaglutide and every other compound is sampled, sent for independent HPLC-MS analysis, given a traceable lot reference, and published with its test date before it goes on sale.
Open The Batch BookIndependent HPLC-MS
Identity, purity and mass confirmation from a third-party laboratory, not an in-house claim.
Traceable lot codes
The reference printed on your vial matches a dated entry in The Batch Book.
Published before release
Linked from the product page and the index — read it, then decide.
KP-99 release floor
Below 99% and the lot is quarantined rather than discounted.

KIWI PEPS FAQ
Straight answers before you order
Who are Kiwi Peps?
+
Kiwi Peps Limited is a New Zealand-owned research peptide supplier. Stock is held and packed here in New Zealand, every lot is independently HPLC-MS verified before release, and the certificate of analysis goes straight into The Batch Book for anyone to read.
Why does Retatrutide lead the range?
+
Retatrutide is the compound New Zealand labs reorder most from us, so we hold the deepest stock in it across 10mg to 50mg. Every Retatrutide lot clears the KP-99 Purity Standard and ships with its own dated analytical certificate.
How fast will my order reach me?
+
Bench-Ready Dispatch means a transfer cleared by 2pm NZT leaves us the same working day on tracked NZ Post CourierPost. Most main-centre addresses land next working day; rural delivery adds one to two days.
How do I pay, and are there surcharges?
+
New Zealand bank transfer through your normal online banking — ANZ, ASB, BNZ, Westpac, Kiwibank and the rest. You get an account number and a Kiwi Peps Reference Number at checkout. No card processors, no surcharges, no minimum beyond the NZD $100 order floor.
Can I see the certificate of analysis before I buy?
+
Yes. The Batch Book is public. Look up the lot, read the HPLC-MS result and the test date, then order. If a lot has not been published yet, it has not been released.
What are these products actually for?
+
In-vitro laboratory research only. Kiwi Peps supplies materials to researchers, not consumers. Nothing we sell is a medicine, supplement or therapeutic product, and none of it is intended for human or animal consumption.
