Product
All Perplexa Labs peptides are independently verified at ≥99% purity by HPLC (High-Performance Liquid Chromatography), with identity confirmed separately by mass spectrometry. Every batch is tested by an accredited U.S. third-party laboratory — not in-house — and a Certificate of Analysis is published on the product page before the lot is listed for sale.
Every order ships with a lot-specific COA showing the exact purity percentage, molecular weight verification, and identity confirmation for the vial you received.
