Our Testing Process
Every compound we sell is independently tested by accredited third-party laboratories using HPLC and mass spectrometry analysis before it leaves our facility. Batches that do not meet our ≥99% purity specification are rejected — full stop. No exceptions.
Certificate of Analysis (COA)
Every lot we release is tested by an independent laboratory, and its Certificate of Analysis is published against the batch number printed on the vial. Certificates remain viewable from your account dashboard under My Account → Lab Results. Each COA records the batch number, test date, methodology, and measured purity for the exact material you received.
Purity Standards
We source only research-grade raw materials and synthesize to ≥99% purity specifications verified by independent HPLC analysis. Our quality threshold exceeds most commercially available research compound suppliers. If a batch falls below standard, it is not sold.
US Domestic Shipping
All orders ship from within the United States with a processing time of 48 hours or less. Shipments use plain, protective laboratory packaging with no external branding indicating product contents. Standard domestic delivery is 3–5 business days.
Research Use Only
All compounds offered by High Level Compounds are strictly for in-vitro laboratory and research purposes. We require all purchasers to acknowledge this at checkout. These products are not for human or animal consumption, diagnosis, treatment, or prevention of any condition or disease.
