Why buy this peptide from NuVion

Most of the NuVion range has been tested by Janoshik Analytical, an independent laboratory, and the vast majority of results have come back above 99%. Each product page shows its own testing status, so you know before you order exactly what has been measured and what has not.

Testing status on every page

Where a product has a published result you get the measured purity, the date it was analysed and the full certificate. Where there is not one, the page says so plainly instead of leaving a gap you have to notice.

Australian stock, domestic post

Nothing crosses a border after you order. Stock is held in Melbourne and goes out in plain outer packaging with protective inner packing, tracked from dispatch.

After reconstitution
Reconstitute with bacteriostatic or sterile water, keep refrigerated and use within four weeks. Avoid repeated freeze-thaw cycles.

What customers say about NuVion

The purity matched the certificate of analysis to the letter. Reassuring to finally find a supplier that backs up its claims with documentation.
Daniel R.
I cross-referenced the HPLC results independently and everything lined up exactly. The purity was as stated, the identity verification was thorough, and the paperwork was complete.
Emma L.
Had a question about reconstitution and storage and got a clear, properly informed answer within the hour. You can tell the people behind this actually understand the products.
Priya N.
The batch testing data was provided up front without me having to chase it, and the figures matched what I'd expect. My only gripe is that delivery took a day longer than the estimate suggested.
James W.
NuVion HealthFair call on the day. We have moved to a same-day dispatch cut-off at 2pm AEST since, and tracking goes out the moment the label is printed. Thanks for ordering again.

Questions

How do I know the vial contains what the label says?
Most of our range goes to Janoshik Analytical for RP-HPLC purity and mass spectrometry identity. Where a product has a published result, its certificate sits on this page with the measured purity and the date it was analysed, and where the result is held on Janoshik's own server the report opens there. Not every product has a published result yet. If this page does not show one, ask us and we will tell you where it stands.
What purity is this peptide and who tests it?
Testing is done by Janoshik Analytical, an independent laboratory used widely across the peptide research sector. Purity is measured by reverse phase HPLC and identity is confirmed by mass spectrometry. Recorded purity sits above 99% on the vast majority of tested samples. Where this product has a published result, the exact figure and the full certificate are shown further up this page.
How should this peptide be stored?
Keep the sealed vial cool, dry and out of direct light. Lyophilised powder held this way does not need refrigeration until it is made up. Once reconstituted with bacteriostatic or sterile water, keep it refrigerated, use it within four weeks and avoid repeated freeze-thaw cycles. Our reconstitution calculator works out the volumes.
How fast will it arrive, and what turns up at the door?
Stock is held in Melbourne and most orders leave within one business day, arriving in 2 to 7 business days. Orders go out in plain protective packaging, and every order is tracked from dispatch.
Do you ship this peptide anywhere in Australia?
Yes. Stock is held in Melbourne and posted to every state and territory, so nothing crosses a border after you order. Shipping is a $15 flat rate and free on orders over $300, tracked from the moment the label is printed.
Can I order this peptide at wholesale volume?
Yes. We supply research groups, institutions and distributors ordering at volume. Get in touch with the quantities you need and we will come back with pricing and lead times.
What if my order arrives damaged or something is wrong?
Message us and we will fix it. A damaged vial, a wrong item, or a product that falls outside its stated specification on receipt gets sorted the same business day. Beyond that, these are research materials, so ordinary change-of-mind returns are not something we can accept. Full terms are in the returns policy.
