I like to get our product from places that actually 3rd party test the stuff and give me the results. There are a few places that do this, but recently we've switched to hempextracts.com and we like them.
We're using CBD and it definitely helps you sleep. We are using full spectrum with THC (.3%) and it does not get you high. It's from Hempextracts.com
I would recommend anyone with PD to try it as well.
