I just used one of RK's kits, 4g one here.

I am a little paranoid, so I used a 10cc syringe to re-measure everything. I re-measured the BA, and since I wanted a higher concentration, I measured my oil too and used only what I needed.

I used the "how to make higher concentration" page off Gotfina and then I did a little math to figure exactly how much oil to add to get 100mg/ml.

It's pretty easy and results are yummy!
