About Us
ABOUT US
Great North Bio supplies Canadian laboratories with a reliable domestic source of high-purity research peptides. We exist to give researchers a faster alternative to international shipments stuck at the border.
Every product we sell is independently tested by a third-party analytical laboratory using HPLC and mass spectrometry. Our standard is greater than 98% purity, verified batch by batch. Certificates of Analysis are available on request for every product.
We ship from our Canadian fulfillment center with tracking on every order. Plain unmarked packaging. No border delays. No surprise duties.
