For people who read the label.
Norwin is a research-peptide catalogue with the paperwork up front. What a thing is, which lot it came from, and the certificate for that lot, before you add it to the cart.
Who we are
Norwin is a small team in North County, California. We built the catalogue for people who read labels: the structural class printed on the vial, the lot number where you can find it, and the certificate a click away.
What the catalogue is
A short list, kept short on purpose. Each listing is sorted by structural class, analog, fragment or cofactor, and described by what it is. Sizes and prices are on the page, the vial is 3 mL unless the listing says otherwise, and nothing renews.
How to read a certificate
A certificate of analysis is the laboratory's report on one lot. Start with the lot number and check it matches your vial. Then read the identity result, which confirms the material is the named peptide, and the purity figure, which is the share of the sample that is that peptide. A lot whose report has not arrived is marked pending on the testing page, and Norwin never fills the gap with a number.
The one rule
Everything here is sold for laboratory research use only. Nothing is for human or animal use, nothing is described by what it might do, and you must be 18 or older to order. Checkout asks you to confirm both, on every order.
“The label says what it is. The certificate shows it.”
That is the whole standard.What is behind every vial
Three things, and all three are written down.
A structural label
Name, class, amount, lot number and the research-use statement. Nothing else.
A lot certificate
Identity and purity from an independent laboratory, filed under the lot number on the vial.
A plain box
Cold-packed and shipped from inside the United States, with tracking and nothing on the outside.
Start with the certificates.
Read the reports first, then the catalogue. That is the order we would use.
