The Science Behind Purity
Numbers that speak for themselves.
HPLC Purity ≥99.6%
Every batch undergoes High-Performance Liquid Chromatography analysis. If it doesn't hit ≥99.6%, it doesn't ship.
Batch-Specific COA
A Certificate of Analysis unique to your batch is included with every order, confirming identity, purity, and molecular weight.
Mass Spec Confirmed
Identity is confirmed via mass spectrometry — not just assumed. You receive the compound you ordered, every time.
Lyophilized Powder
Freeze-dried for maximum shelf stability. Lyophilized format is the gold standard for long-term peptide storage.
Cold-Chain Shipping
Shipped with dry ice or gel packs in insulated packaging. Temperature integrity maintained from our facility to your lab.
AHG-Compliant Naming
All compounds are labelled using AHG-compliant naming conventions — no ambiguity, no confusion, full regulatory clarity.
Our Standard
Every compound we supply is HPLC-verified, documented, and shipped with a Certificate of Analysis.
We don't cut corners on purity. Every batch is tested by a third-party laboratory before it leaves our facility. You receive the data, not just our word.
Research-grade quality
Doctor-trusted compound options
Quality & Compliance
Every vial. Every batch. Documented.
Each compound ships with a batch-specific Certificate of Analysis confirming identity, molecular weight, purity, and storage conditions. Our labelling follows AHG-compliant naming conventions throughout.
