About Northstar Labs.
A US-based research peptide supplier built around a single non-negotiable: real documentation for every batch we ship.
Built for the researcher who refuses to trust the unknown.
When research outcomes depend on the integrity of the input compound, vendor transparency stops being a nice-to-have. Every Northstar lot ships with a downloadable third-party HPLC Certificate of Analysis. Every label is batch-traceable. Every step from synthesis to door is auditable.
Independent Verification
Every batch tested by an outside HPLC lab — our suppliers don’t grade their own work. Results published per-lot.
Full Documentation
Certificate of Analysis, mass-spec reports, and batch records — all downloadable from your account dashboard.
