Anyone heard of these Concentrates?

Hi all. Was having a look at one of the Concentrate suppliers sites here where I am and they have got some new ones in that I have never heard of before.
One is Purilum. There are some very interesting flavours on the list.
The other is Flavour Revolution. Supposedly super concentrated with just 2 to 3% needed to give a full flavour.
Anyone heard of them before?

Ive seen Perilum popping up quite a bit in recipes from mixers from over the pond and heard good reviews on DiyorDie so I'd try them but don't know of a UK vendor

Hmmm, will have to get some next order and give a few a go.

Yeah I deffinantly would, maybe have a look on AllTheFlavors and find which are the most popular flavoirs people are using. I've not seen them here in the UK yet
