The Australian research peptide supplier guide

Research peptide suppliers, checked against the evidence.

We score every supplier we list on the same 16 checks: 14 facts anyone can confirm on the supplier’s own website (lab reports that carry a lab-side check and name the supplier, an ABN, Australian dispatch, published policies), plus how many of the products you can order today have a public report, and an ABN register lookup. Every item we found links to the page it came from.

The rankings

How the suppliers compare

Every supplier is ranked by its transparency score alone, highest first. Equal scores share a rank and are listed alphabetically. A score counts only what we could confirm on the supplier’s own pages when we checked them.

Showing the 5 highest-scoring of 29 suppliers, checked from 27 September to 6 October 2026. “Not found” means not found on the pages we checked at the time. It is not a claim that the supplier doesn’t offer it. How the score works

What we check

What we check, and why it matters

100 points across four groups. They come from the 14 checklist facts read on the supplier’s own website and the lab reports it publishes, plus the share of the products you can order today that have a public report, and an ABN lookup on the Australian Business Register. Nobody types a score in by hand.

    Lab testing

    A lab report is strongest when the lab that ran it will show you the same report, and when it names the shop showing it. We sample the first reports each supplier lists, ours included, record what each one we could open shows, and count how much of what you can order today has a report.

    • Certificates of analysis published on the site12 points
    • COAs checkable at the testing lab (verify link or key)12 points
    • Reports name this supplier12 points
    • Share of the products you can order today that have a public report4 points
  • 25 points

    Business identity

    An ABN on the register and a named legal entity tell you who you are buying from, and who is answerable if an order goes wrong.

    • ABN displayed on the website8 points
    • ABN active on the Australian Business Register5 points
    • Legal entity named4 points
    • Business address published3 points
    • Contact email published3 points
    • Contact phone published2 points
  • 20 points

    Australian fulfilment

    Dispatch from within Australia keeps an order in the domestic post. A written policy sets out fees, timeframes and tracking before you pay.

    • States it dispatches from Australia10 points
    • Shipping policy with fees and timeframes5 points
    • Tracked delivery stated5 points
  • 15 points

    Policies & labelling

    A published refund policy and terms tell you what happens when something arrives wrong. Research-use labelling shows how the supplier describes what it sells.

    • Refund / returns policy published6 points
    • Terms and privacy policy published4 points
    • Research-use-only labelling5 points

Reviews are shown on supplier pages but add nothing to the score: a star rating isn’t something a buyer can verify, and scoring it would reward whoever collects the most. The score also doesn’t rate what is in a vial. We don’t lab-test other suppliers’ stock, so we don’t pretend to.

How to check a COA

These four steps work on any report that carries a lab verify link or key, whichever supplier it comes from.

  1. 1

    Find the report for your product

    Open the supplier’s COA for the compound and vial size you are looking at. Note the lab’s name and the task or report number.

  2. 2

    Open it at the lab, not the shop

    Use the verify link or key to load the same report on the lab’s own website, and check the address bar shows the lab’s domain.

  3. 3

    Match every detail

    Compound, declared amount, sample date and task number should match the supplier’s copy exactly, and the client field should name the shop you are buying from. A PDF that only exists on the supplier’s site can’t be checked this way.

  4. 4

    Read what was measured

    Single-compound reports give purity as a percentage. Blend reports give the measured mass of each compound per vial instead, so they carry no purity figure.

These are Au Peptide Labs reports, used because we run Au Peptide Labs and hold its full report list. Each link opens the report on the testing lab’s website, so you can check it the way you would check anyone’s.

hello@aupeptidelabs.net
Who owns Vialwise?

Vialwise is owned and published by APL Research Pty Ltd (ABN 53 700 008 019), which also operates Au Peptide Labs. We say so beside every ranking and score, and in the footer of every page, so you know who is behind the comparison before you rely on it.

How we handle ownership
How is Au Peptide Labs ranked?

Au Peptide Labs is our store, and it is ranked the same way as every other supplier: scored by the same code, against the same checklist, and not pinned. Suppliers are ordered by score, and equal scores share a rank and are listed alphabetically.

How the list is ordered
Do suppliers pay to be listed?

No. No supplier pays to be listed or ranked, and nobody chooses where a supplier appears, our store included: the order comes from the score. We find Australian suppliers ourselves and check the same public pages for each one. Any supplier can send a correction with a link to the page that shows it, and we will recheck that item.

Send a correction
Does a high score mean the product is good?

No. The score measures how much a buyer can verify about a supplier from its public pages: lab reports, business identity, Australian dispatch and policies. It does not measure what is in any vial. We don't lab-test other suppliers' stock, so we don't rate it. A report you can open at the testing lab is the closest thing to evidence about a specific batch.

How the score works
What does “Not found” mean?

It means we looked for that item on the supplier's public pages on the date shown and did not find it. It is not a claim that the supplier doesn't offer it. “Couldn't verify” means a page didn't load, was blocked, or was ambiguous. Both score zero, and both can change after a correction.

How often is it updated?

Every listing shows the date its facts were checked. The current round was completed on 6 October 2026. When a supplier or reader sends a correction with a source, we recheck that item and update the date on the listing.
