it works for about a week for a guy [SEP] hmm let me start off by saying that i am a guy in late s and maybe this deodorant was designed primarily for women but in my case it worked for the first week or so meaning that it would eliminate armpit odors nicely bo but then it started failing at about pm or even earlier in the day and i mean really failing i would smell like i just ran a marathon and then sat in my office for an hour that bad also keep in mind that this product can really stain your dark shirt if it comes in contact with your armpit it leaves those nasty white marks that can be washed off but still a nuisance if you are on a run in the morning so my verdict this product is not for me sorry
