Four checks. Every single batch.
No exceptions, no shortcuts. If a lot doesn't pass, it doesn't ship.
≥99% HPLC Purity
Every lot is independently assayed by high-performance liquid chromatography. We will not ship anything that falls below the 99% threshold.
Mass-Spec Verified Identity
Molecular identity confirmed by mass spectrometry on every batch — you get the peptide on the label, full stop.
Endotoxin Tested
Lots are screened for endotoxin contamination so your in-vitro work isn't compromised by upstream impurities.
Batch-Specific COA
A Certificate of Analysis is tied to the exact lot you receive — not a generic spec sheet for the product line.
A controlled chain — from lab to your bench.
