Received a sample. Has lasted me 5 days and no stink, including showering twice a day, walking and pilates. Unbelievable! I was using natural deodorants for about a year now with 2 popular brands, so I think my body is used to natural deodorants but was finding I was smelling by end of the day or when I woke up before shower doing chores or light pilates and stretching I smelt. I am going to purchase one now as honestly I cant believe it! so good....!!! Hoping it'll keep going. Always best to let your body purge for a week to a month before natural products work. It took me about 3 weeks originally.
