I was given some samples for a review. I had aeng da, white borneo and red bali, and they were all pretty decent. I ended up enjoying the maeng da most of all. I used it for a long day of catching up on laundry and it powered me through and kept my pain at bay (the best kratom can) without making me sleepy. Usually kratom that helps my pain makes me sleepy (which I usually don't mind, but I needed energy for my chores), but this was energizing and still offered some pain relief. I really liked it, and the others were good too. The red bali and white borneo were sleepy (whites are usually sleepy strains for me), and offered pain relief.
