I finally got some interesting result with 6 ml, definetly a significative effect(but nothing like smoking) lasting about 2-3 hours, 40 mins after ingestion. I guess I skrewed the pre-baking step again. It is the sensitive step for sure. Next time I'll use 250 F, 20 minutes. I'm so exited about getting it done correctly, I don't want to loose another 8th.
