the one i used was blue print cleanse. it's pretty popular here in ny. apparently they have a lot of celebrity clients. they also ship all over the US.

i picked level 3 (least amount of fruit/sugar) because i've done this before. it is kind of pricey but i was able to get a 25% discount with a code. i'm not sure if they're running any promotions currently. anyway, good luck with your cleanse!
