Frequently asked questions.
The most common questions we get, answered directly.
What is Nordvik?
Nordvik supplies research-grade peptides and related compounds, each backed by third-party Certificate of Analysis testing for identity and purity. Every product is sold strictly for laboratory research or other legitimate business use.
Are your products for human use?
No. Nothing sold on this site is intended for human or veterinary consumption, and we don’t provide dosing or administration guidance of any kind. See our Terms of Use for the full research-use restriction.
Do I need to create an account to order?
You can browse and check out without an account, or create one to track order history. There’s no approval process — accounts are standard and self-serve.
How is quality verified?
Every lot is tested by an independent third-party laboratory before it ships. You can look up the Certificate of Analysis for your lot on our COA Lookup page. See Our Standards for the full testing methodology.
Where do the molecular identifiers on product pages come from?
Molecular formula, weight, CAS number, PubChem CID, and structural data are drawn from PubChem’s public compound database, not written in-house — so you can independently verify them against the same source we used.
Do you ship internationally?
We currently ship within the United States. See our Shipping Policy for details, and contact Order Support about international requests.
Can I return a product?
Products can’t be returned once shipped, for the reasons outlined in our Returns & Refund Policy — but we’ll replace or refund damaged, incorrect, or documented quality-issue orders.
