    This kratom powder is the best thing I have ever put into my tea since Earl Grey. I have been a huge fan of OPMS ever since they have gotten into the kratom game and time and time again they have proved that they are the best. This is the finest Maeng da powder that I have encountered in all of my kratom journey. I enjoy getting my supplies from Kratom Lords, they know their stuff and do right by me always.
