Finally got to make this yesterday. My decarb ended up at 245F for 35 minutes. The only slight problem was the mixing of ingredients. I added the lecithin to the warm decarbed shatter no problem. When I added the room temp mct oil, the shatter did not mix in. The BHO hardened into a thick clump and was stuck to the stirring rod I was using. I decided to give the whole mix a few seconds in the microwave to warm it all up. After about 20 sec the mct oil heated up a bit and the BHO mixed in well.
1 ml should be around 25mg but it's all based on estimation. I had no idea of the actual THC concentration of the shatter so as I've read here, I guestimated it at 750mg per gram.
Took 0.5ml this afternoon and didn't feel much beyond maybe a little head warming. Just took about 0.8mg in my second attempt, and made sure I held it under the tongue for 2 minutes.
After about 20 minutes I was feeling pretty chill.
So far, so good.
