I took tongkat ali from therootofthematter.ca about 20 grams in a 3 month period. I did notice an increase in wellbeing over the first week and increased aggression playing football. Every since i stopped taking it, my aggression slowed down. I dont know how much tongkat ali increases testosterone cause i know increaed libido doesnt always mean increased testosterone and nothing changed really while on it as far as libido. I do belieave though that it increases testosterone just wish i had bloodwork. Anyone else have such experiences?
