Lot lookup
Enter the lot number printed on your vial label, or scan the QR. We return the per-batch HPLC chromatogram, mass-spec confirmation, purity result, and release date. No account required. Anyone can verify any vial we have ever shipped.
Lot # is printed on every vial label and inside every shipping box.
Why this exists
The RUO peptide market has a documented credibility problem: most suppliers ship a generic spec sheet that describes what the molecule should be, not what your specific vial actually contains. We refuse that compromise. Every released lot is queryable by anyone, forever. If you ever doubt a result, email research@xfactorpeptidelab.com and we will pull the −80°C reserve and re-run the assay.
