Choosing an Australian supplier
The 16 checks behind every Vialwise score, from lab reports and ABNs to Australian dispatch and policies: what each one tells you, and where to find it.
Buyer guides
Check a supplier before you order, not after
Plain-English guides to the checks behind every Vialwise score: reading a lab report, confirming who runs a website, and looking after lyophilised material once it arrives. Each one links to the tool or page that lets you do the check yourself.

Who writes these guides
The Vialwise editorial team. Each guide describes a check you can run on any supplier’s website yourself, and links to the tool or page that lets you do it. Point weights are read from the scoring code itself, so a guide can’t quote a weight the scores don’t use.
Vialwise is published by APL Research Pty Ltd, which also runs Au Peptide Labs. Every supplier, ours included, is scored on the same published checklist. How we handle this
Research use only. Everything on Vialwise concerns research-grade material sold for laboratory and analytical use only. It is not a registered medicine, is not supplied for human or veterinary use, and nothing here is medical advice.
