I’ve had both the shatter and isolate from drip hacks and dissolved it in pg. 1g in 20ml with the isolate, 30ml with the shatter, this was my first attempt, tried to go stronger with the isolate. Purely so i had to puff less, rather than ingest more, as it doesn’t taste great. I ended up mixing both together in the same bottle. They both put me to sleep, the shatter seemed to work a little bit better and I’m not sure if this is because it contained “terpenes”. I now have both mixed together in the same bottle.
I also had some from ukcbdvape.com which also worked.
I’d say at a guess my average use would be once or twice a week. It’s been less frequent since we had a baby in december, I’m shattered most of the time these days.
