Some people don't react best to homozon. Those who don't prefer colosan, or colozone.
I would stay away from Oxypowder
, but some people like it. I used to highly recommend Homozon to everyone, but then I discovered some people do better on colosan because of how their body works.
Try colosan, maybe even try it first and then if it doesn't work try the others. Don't buy it from the website that claims to be "raw foods", I have heard they have poor customer service. The oxystore is a great place for colozone.
