They have Kratom in a liquid and powdered extract as well as micro ground raw leaf, Hot and Cold teas. Not entirely sure if they have pill capsules but i assure you, the Boom powdered extract washed down with tea or water is extremely pleasant and I'd assume exactly the desired effect you're looking for.
Probably best to check with the store directly.
When I visited it was not offered to me. They had pre made teas and drinks that were far better.
