    Extremely effective Kratom. I was slightly wary of Sumatra kratom but OPMS always comes through 10/10.

    This is a rather solid Red Kratom. It’s a more rounded version of Red Bali as far as my experience goes. OPMS is way well known and on the back of that I made an order of this obscure kratom strain only to really enjoy it. Money well spent.

    Sumatra Kratom is absolutely one of the best red kratom strains!!! If you are looking for something to drink and relax on those afternoons when you want to disconnect from a stressful day… this is your best kratom option!! I used to drink it in a regular mixture but the taste wasn’t good at all, but do yourself a favor and learn to brew a kratom tea – it is amazing, even my wife loves it too!

    Hands down meaningful customer service. I ordered in and got my tracking immediately but the product was a little stagnant in the pipeline on Monday. I called in to inquire and I was gently reminded that though the order was packed and ready to ship, USPS would not be picking it up until Tuesday since it’s Labor Day. 🤦🏻‍♂️ Duh lol. Package arrived promptly and I found a cool sample in it which was super nice. I’ve been ordering from these guys for close to a year now and their customer service is spot on.

    Sumatra kratom is outstanding. This has to be one of the best red kratoms I’ve tried in a long time. I have been taking maeng da reds for a while now and for some reason decided to go with the Sumatra – excellent is all I could think of. It will be a no brainer reorder for me.
