REFER 3 GET YOURS FOR FREE!!!!!! If you invite 3 friends to do the challenge with you, you get yours free. :) This is a great deal. We also offer a 30 day money back guarantee. We are the 90 day challenge even our founders have done the 90 day challenge. It really tastes great and I love it as I am always on the go. We offer online support for those that need or want a little extra support. I love the energy. There are different kits and each has something special to offer, or you can order and choose what you want in your 90 day challenge. We do most of our orders auto ship ( which means every month you should get your kit the same day of the month) or you can try to remember to order it every month. This is truly and amazing shake. If you would like to taste it before you buy it let me know and we will work out a time to meat and do a "shake party."
