i guess tiny i was mistaken... i thought you had two bottles of blaze and one of fierce.... i didnt want to compete againts my buddy Lern for the one bottle of firce so i said i would do the blaze..... but fierce is fine by me, as long as it doesnt keep me up at night.....
It does have caffeine in it, which yes - caffeine can keep you up at night if you take it too late. Caffeine has an effective half life of about 4-6 hours in the body (depending on conditions I believe). That's all that could keep you up at night though.
