No. Pure North Peptides ships to Canadian addresses only. Insulated tracked shipping is included on every peptide shipment via Canada Post Xpresspost; most addresses arrive in ~4 days.
Every lot is independently tested by Janoshik Analytical on RP-HPLC before we list it, and we verify the lot again before any vial leaves our cold storage. The 99% number is the most-recent independent measurement, not a synthesis spec. If the verified number drifts below threshold, the lot does not enter inventory.
Yes. Email purenorthpeptides@proton.me with the SKU and we'll send the lot's Janoshik report (HPLC chromatogram, MS identity, LAL endotoxin) as soon as we can. Historical lot data is also available on request.
Often, yes. Email purenorthpeptides@proton.me with the compound and the quantity you need. We'll let you know whether we can source it and have it independently tested by Janoshik before it ships, along with lead time and pricing.
Every released lot has a retain held under storage spec for five years from release. You can email purenorthpeptides@proton.me with the batch number from your order to request the lot's COA for any past lot we've shipped.
