The effects were really unnoticeable with the exception of becoming sick. I suspect it was either a bad or contaminated batch. It was definitely on the stale side too and was a bit clumpy towards the top of the bag. I even checked the report of it online too before leaving this review and saw no cause for alarm. Maybe it was contaminated somehow during the handling and packaging before it was shipped? I don't know. However, it was the worst kratom I've ever purchased from Kraoma in nearly 3 years.
