How to read a COA

Each COA lists the cannabinoid concentration as both percent (%) and milligrams per serving (mg). Our products are formulated at 5mg Δ9 THC per 12 fl oz can. Variances of ±10% are normal and within FDA-allowable limits for hemp products. If you see a result outside that range, contact us — we'll replace your purchase.
