I got the idea and the recipe loosely from here:

However, not having such fine scales required to measure 150mg I scaled it up to use the full 1g.
When I made up a batch of PC I made it pretty much the same. Haven't used much of it yet as buds kicked off by the home made e gel are still happening.
I believe you can substitute Isopropyl for DMSO, but make sure you read all the precautions and warnings before heading down that path.
Good luck!
