Frequently Asked
-
Isolate is a single pure cannabinoid, 100% CBD (or CBG, or CBN) and nothing else. Full-spectrum hemp oil carries the plant's whole array of compounds, including low levels of THC; broad-spectrum removes the THC but keeps the rest.
Most published research was conducted with isolate, which is one reason we build with it: the same product every time, easier to dose precisely, and 0.0% THC on every batch's lab report.
-
