Sourcing & Testing Transparency

Northernpeps partners with ZC Labs, an established research compound supplier, to source and fulfill every product in our catalog. ZC Labs manufactures and supplies these compounds, and arranges for an independent, accredited laboratory to test each batch before it ships — ZC Labs does not perform the testing itself, but manages the testing process and the resulting Certificates of Analysis.

Because ZC Labs is the manufacturer and supplier of record, the Certificate of Analysis for your order will show ZC Labs — not Northernpeps — as the company that arranged the testing. The purity, identity, and lot data on every certificate is accurate and fully verifiable by lot code, regardless of which company name appears on it. We disclose this partnership openly so you always know exactly where your research materials come from and who stands behind the testing.
