i have very bad armpit odor but cant smell anything. occasionally i do notice a sulfurous pungent smell but it happens rarely. so if i ever find something that works how am i gonna know if its actually working? for example i tried zinc oxide because there is research which says it works for body odor and also a girl on this site said it worked for her too. so how am i gonna know its working or not if i cant smell any odor so i cant tell if its decreasing or being neutralised?
