The mint inside was a bit oily, but tasted pretty great. I think it contains coconut oil? I wish these were made with milk chocolate as the dark chocolate is pretty hard, and doesn't mix with the mint for the creamy consistency I would have loved. Also wish there was more of the mint inside, instead of a small layer between a lot of chocolate.
As for the potency, wow! I've taken 30mg-50mg oil capsules with no effect, and just a 1/4 of this little chocolate had me feeling great!
