Continue§02 · VERIFICATION STANDARD
Batch-Level Verification — Not A Generic Claim.
Plenty of suppliers test one lot and reuse that certificate across every shipment that follows. Every batch that reaches NZ Peps is independently HPLC-MS tested by an independent laboratory, assigned its own batch identifier, and published with its own Certificate of Analysis on a public archive. If we dispatched it, you can look it up.
§02b · OUR APPROACH
A Transparent, Research-First Approach.
NZ Peps exists to support New Zealand laboratories, universities and independent researchers with documentation, traceability and unedited analytical results — not marketing spin.
Independent batch testing
Every lot ships with its own Certificate of Analysis from an independent laboratory — never a single certificate reused across multiple shipments.
Batch ID & traceability
Each batch carries a unique identifier from intake through to dispatch, linking your order to one specific, documented lot.
Controlled handling
Reference materials are lyophilised, sealed under nitrogen and stored under controlled conditions in tamper-evident packaging before dispatch.
Verified stock only
Only batches that clear our published purity threshold reach inventory. Anything under-spec is rejected before it ever ships.
Our focus is process, quality and clarity — not marketing claims.
§03 · METHODOLOGY
How We Verify Every Batch.
A four-stage protocol. No batch reaches the catalogue until every stage is documented.
Intake & quarantine
Every incoming batch is quarantined, barcoded and logged against its supplier and receipt date before independent testing begins.
Independent HPLC-MS
Samples go to an independent laboratory for HPLC-MS purity analysis. We publish exactly what the lab reports — unedited, with its signature.
COA published
Each Certificate of Analysis is uploaded to the public Lab Results page, tied to its batch number and archived for future reference.
Dispatched from NZ
Only batches with an in-spec, published COA leave our warehouse. Same-day dispatch on orders paid before 2pm NZST, with no customs delays.

§05 · FREQUENTLY ASKED
Research Questions, Answered.
Clear answers on testing, sourcing and traceability.
Q.01What does independent testing actually involve?＋
Every batch we receive is sampled and sent to an independent laboratory for HPLC-MS purity analysis. The lab issues a Certificate of Analysis directly, and we publish it on our Lab Results page against that batch's unique identifier — the testing lab is named on every result card.
Q.02How do I check the COA for the batch I received?＋
Your order confirmation and account both list the batch number allocated at dispatch. Enter that number on the Lab Results page to open the exact COA — purity, method and test date, tied to your specific lot.
Q.03What purity threshold do you enforce?＋
Our minimum acceptance threshold is 99% HPLC-MS purity. Any batch that doesn't clear this bar is rejected at intake and never reaches inventory. Every published COA shows the actual measured result.
Q.04Why is this positioned as research-only?＋
Everything listed is supplied strictly for in-vitro laboratory research and analytical reference use. We make no medical, therapeutic or performance claims, and materials are not for human or animal consumption.
Q.05Do you ship outside New Zealand?＋
NZ Peps dispatches nationwide from stock held within New Zealand. Because nothing crosses a border, there are no customs delays — orders paid before 2pm NZST go out same day.
Q.06What happens if a parcel is lost or damaged?＋
If your parcel is confirmed lost or arrives damaged, we issue store credit once the courier investigation is complete. Message support@nzpeps.co.nz with your order number and tracking, and we'll follow it through.
