Will i still feel the effects at lowered dose?

Yeah I've been using kratom for on and off for years now. I just have a question. If Im using 9 grams twice a day for the last week. If I use 5.2 grams of white mangda letting it soak in lemon juice for 20 minutes then pouring hot but not boiling water with it and let that sit for 10 minutes will I feel the effects I want the stimulate effects of white mangda?
