Hehe, I guess I could have linked to some of my previous posts on this topic. I've done quite a few of them, including at least 10 step by step posts, with videos. But your suggestion is a good one, when I post about making this oil I'll either do another step by step, or link to a previous one.
The capsules have about 700mg of infused oil in each. Stronger infusions (with less carrier oil like MCT, olive, etc) would have as much as 500mg of THC (half a gram!)... normally I mix in some other oils for absorption so there's probably about 200mg THC, plus some other noids like CBD, CBN, THCV, etc.
