Red Hulu Kapuas Kratom Review Dose: 12g (high opiod tolerance) Had like 8g (4 x 4cc scoops) then another 2 scoops so around 12g. 45 mins in a wave of warmth hits the noggin and body, very nice muscle relaxation which is a nice surprise, taste is slightly bitter, kind of like a red borneo but stronger even though the RB was more bitter, nice rosy cheeks, 9/10. From Kraatje. Trying Red Riau next.
