I sometimes add coffee but it doesn’t do much for me, but yeah so for me rotating 3 strains is efficient and enough to mitigate tolerance (gmd, gm, rb) two greens and one red. i usually take from 1-3g. When i go past 3g and bunch of times a day it doesn’t work so well so might keep in mind to take time inbetween doses and try less cause i have noticed less is more with kratom 100%.
