    The king of all kratom capsules – Malay kratom. I get an unbeatable amount of energy from this and it definitely knocks my back pain out of the park. I order 3-4 bags at a time and get free shipping also, how cool is that. And it’s not the junky snail mail that takes forever to reach, I’ve always got my kratom in two days flat and I live at the other end of the country. Highly satisfactory overall – 2 year long user here.

    Malay kratom – It’s affordable and effective and unbeatable, so much better than Maeng da. This feels like a much more premium version of what I’m used to. A+ all the way. Their free shipping is cherry on top, I’m a regular user so ordering a few bags is easy and their shipping is reliably fast.

    Malay kratom is excellent. I was hesitant to try kratom because I didn’t know how to measure it out, but after doing some research, it’s actually quite easy. 6-8 kratom capsules hit the spot. The effects are worth it

    I prefer green vein kratom because it gives me a boost of energy without making me feel jittery. Between Maeng da and Malay, Malay kratom is definitely the superior of the two. I snag a few bags each time and rotate with maeng da as well to offset any possible tolerance build up. And tapering is a must.

    I tried Malay kratom capsules for the first time and am very pleasantly surprised by the results. This is much better than maeng da capsules in everyday. Very easy to recommend to anyone who is looking for a fantastic green kratom.

    OPMS Malay kratom is my FAVORITE. I have been using Ibuprofen for a number of years for arthritis pain. I was hoping to replace it with opms kratom . By doing it slowly over a period of three weeks, I was able to discontinue Ibuprofen completely.

    I loved my opms green maeng da, especially in the capsule form. This is such a tried and true kratom and one of the most consistent kratom varieties I’ve tried over the years. This is one of the few brands that I feel safe using time and time again and I have incorporated it into my daily routine for a long time now with highly positive results.
