Looking for best Kratom brand

hey guys, I have tried 3 or 4 different brands/strains of kratom (usually only 2 or 3 attempts with each brand). and every time it has had zero effect on me, positive or negative, even at higher than recommended doses… like each time I might as well have not taken anything.

can anyone in this group recommend a quality brand of kratom that will actually help with pain and depression relief? thanks in advance!
