Our Promise
The AUREX Purity or Free Guarantee
We are the only supplier confident enough to stake our revenue on our purity claims. If our compound does not meet the purity stated on the COA, you get your money back and a free replacement.
How it works
Order any compound
Place your order from our catalog. Every compound ships with a full Certificate of Analysis documenting exact purity, mass spectrum, and HPLC chromatogram.
Test with your independent lab
Submit your compound to any accredited analytical laboratory of your choice. We recommend HPLC-MS testing for the most accurate purity verification.
If purity falls short, we make it right
If your independent lab results show purity below our stated COA value, we issue a full refund and send a free replacement compound at no cost.
Why we offer this
Most suppliers hide behind disclaimers. We built our entire business on analytical rigor: Fmoc solid-phase synthesis in cGMP-compliant US facilities, multi-stage HPLC purification, and independent third-party testing on every batch.
The guarantee is not a marketing gimmick. It is a direct consequence of our confidence in the manufacturing process. When you stake your revenue on product quality, you never cut corners.
