Armpit smells without sweating and with deodorant/antisperant applied. how is that possible ?

Normal: This is normal. Try switching deodorant as this sometimes helps. Try "clinical strength" products. Also realize that everyone has an odor & it's only our culture that makes this a "problem". There are lots of pheromones in sweat that actually are shown to be attractive to the opposite sex. Do not overreact and douse yourself with perfume. Good luck!
