You may discontinue the product at any time and you should not see a rebound effect, however, since we cannot stop the aging process, as the effects of the product slowly wear off the benefits may begin to regress. Of course this depends on the person's age; a person in their 30's should retain the benefits better than a person in their 60's. Some of our clients take the product for several months or perhaps a year and when they are doing well they discontinue the product. They begin taking the product again once they feel they need it again. Some may not feel the need to start the product again for a year or more, it just depends on the individual, their age, what benefits they are looking to receive, and how their body responds.
