I bought mine at a local health store it ran the same price as I've been seeing online 29.95. Here you can learn more about Renew/life products.
I tried to use the paragone after I bought it......not only does it taste disgusting, I was too paranoid of seeing bugs come out of me so I put it on hold. I might get up the courage to try it again since I'm doing the MC. Good Luck, Tia
