I been using Oasis Kratom for YEARS now! There is no better quality! I've tried many other companies but once I found Oasis I never left and never bought from anyone else! I trust their quality. Try them out with their sample packs! My favorites are Green Malay, Green Maeng Da, and White Java(for a little more wake me up and clarity). They lab test their kratom and break down the MIT %! I used to use a local shop here but I kept getting a sinus infection.. turns out it was the local shops bad kratom that had bacteria in it.. I have never had any bad experience I'm with Oasis Kratom! They are always nice and knowledgeable on the phone or email! They are also a vendor of the American Kratom Association! I am really a customer and not being paid, not being sponsored or gifted anything nor do I work for them or even know anyone there. Give them a try. You may just keep using them for years like I have!
