Question 1

What exactly is a research peptide?

Accepted Answer

A research peptide is a short chain of amino acids supplied strictly for in-vitro laboratory and analytical research. NZ Peps products are not medicines, supplements or therapeutic goods, and are not intended for human or animal consumption.

Question 2

What purity does NZ Peps guarantee?

Accepted Answer

Every batch we release is verified at 99%+ purity by an independent third-party lab using HPLC-MS, with the full report published as a downloadable Certificate of Analysis.

Question 3

Where can I find the Certificate of Analysis for my order?

Accepted Answer

Every product page and vial batch code links through to our Lab Results portal, where you can look up the matching COA, assay date and chromatogram before or after you order.

Question 4

Why are some reference numbers redacted on a COA?

Accepted Answer

Submission IDs used by the analytical lab are redacted to protect supply-chain confidentiality and stop reports being lifted and reused elsewhere. Redaction never affects the purity result itself.

Question 5

How is NZ Peps stock sealed and preserved?

Accepted Answer

Stock is lyophilised and sealed under nitrogen at fill time, which is what keeps a vial stable in storage until it is reconstituted for laboratory use.

Question 6

Is NZ Peps stock held in New Zealand or shipped in from overseas per order?

Accepted Answer

Stock is held here in New Zealand ahead of time, which is exactly why we can dispatch the same day and avoid the customs delays that come with importing per order.

Question 7

Who is able to place an order with NZ Peps?

Accepted Answer

Any New Zealand resident aged 18 or over can order. By checking out you confirm the products are for laboratory research only and not for human or animal consumption.

Question 8

Do I need to show research credentials to buy?

Accepted Answer

No institutional verification is required at checkout, though we reserve the right to request more information on individual orders where needed.

Question 9

Is there a minimum order value?

Accepted Answer

Yes — the minimum order subtotal is $100 NZD before shipping. Orders below that threshold cannot be submitted through checkout.

Question 10

Can I combine an in-stock item with a pre-order item?

Accepted Answer

Yes, but the whole parcel ships together once the pre-order item lands, typically within 1–2 weeks. Place separate orders if you need in-stock items sooner.

Question 11

Do you offer store credit?

Accepted Answer

Yes. Store credit is issued once payment clears and is tied to the email address used at checkout — sign in with the same email to apply it to a future order.

Question 12

How do I get a bulk or trade quote?

Accepted Answer

Email support@nzpeps.co.nz with the compounds and quantities you're after and we'll come back with volume pricing.

Question 13

What payment methods does NZ Peps accept?

Accepted Answer

We accept direct NZ bank transfer from ANZ, ASB, BNZ, Kiwibank and Westpac, plus supported card and crypto options where shown at checkout. Bank transfers clear in minutes with zero surcharges.

Question 14

How does the bank transfer reference work?

Accepted Answer

At checkout you're issued a unique NZ account number and payment reference. Include that exact reference so your payment is matched to your order automatically.

Question 15

What happens if I underpay or the reference is missing?

Accepted Answer

Underpaid or unreferenced transfers leave the order pending until the balance and reference are confirmed. Orders unpaid within the checkout window are cancelled automatically.

Question 16

How fast does NZ Peps dispatch orders?

Accepted Answer

Orders paid before 2pm NZST are picked, packed and lodged with the courier the same business day.

Question 17

What courier do you use and is it tracked?

Accepted Answer

All parcels move on NZ Post CourierPost overnight tracked, with a tracking link emailed as soon as your order is lodged.

Question 18

Is shipping free?

Accepted Answer

Yes — nationwide tracked courier delivery is free on all orders over $100 NZD. A flat courier fee applies below that threshold.

Question 19

How long does delivery take to Auckland, Wellington or Christchurch?

Accepted Answer

Metro centres including Auckland, Wellington and Christchurch typically receive overnight tracked delivery the next business day after dispatch.

Question 20

What about rural delivery?

Accepted Answer

Rural New Zealand addresses are fully serviced by CourierPost; simply allow one extra business day on top of the standard metro timeframe.

Question 21

Will my order get held up in customs?

Accepted Answer

No — because stock is held and dispatched from within New Zealand, there are no customs delays or import duties to worry about.

Question 22

How is my parcel packaged?

Accepted Answer

Parcels are plain, unmarked and use insulated packaging with gel packs where a product is temperature sensitive, so contents stay protected and private in transit.

Question 23

How should I store lyophilised peptides?

Accepted Answer

Lyophilised, sealed vials are generally best kept refrigerated at 2–8°C away from light and moisture; some compounds benefit from -20°C for longer-term storage.

Question 24

What's the shelf life once sealed?

Accepted Answer

Sealed under nitrogen and stored correctly, lyophilised peptides remain stable for an extended period. Stability after reconstitution depends on the specific compound and your protocol.

Question 25

Can reconstituted solutions be refrozen?

Accepted Answer

Repeated freeze-thaw cycles can degrade peptide stability, so we recommend aliquoting reconstituted solutions for single-use research applications.

Question 26

Are NZ Peps products for human or animal use?

Accepted Answer

No. Every product NZ Peps sells is for laboratory and in-vitro research use only and is not intended for human or animal consumption under any circumstance.

Question 27

Why might my account be restricted?

Accepted Answer

Accounts may be restricted at our discretion for suspected fraud, repeated non-payment, or misuse outside research-use terms. Restricted accounts cannot place new orders.

Question 28

I haven't received an order confirmation email — what now?

Accepted Answer

Check your spam folder first, then contact support@nzpeps.co.nz with your details and we'll confirm the order status directly.
