A friend has used not this brand and sorry I have no idea which brand. But her son in law looked up the best ingredients no useless fillers and bought from Amsterdam directly and usually in bulk, so it worked out each bottle cost £40 because of this. He said most of the stuff sold in the UK from say Holland & Barrett have very little actual CBD ingredient and bulked out by other unless ingredients. I did ask her more details, but she has short term memory lost and cannot remember as she stopped buying as the price went up and as she is on the basic pension had to stop buying.
