I've used ON mostly. I've also used EARS and Cytosport. I've never had any problems but I think I liked ON the best and always got good deals on it. I haven't gotten any in awhile but I think I might try something different next time.
I think the last one I used was BSN and I never had any problems with it at all. I think my favorite of all so far would be Isopure.
You've tried the isopure powder? I'm usually a chocolate guy do you know if they have that and if so is it good? If not what did you like some "red" flavor? That's usually a safe bet. I can't remember the last time I bought a fruit flavored protein powder but I might go that route.
I use it all the time and I guess that ya, you get some intestinal issues but I noticed only when I dont have meals inbetween. if I am using it as meal replacement not supplement inbetween, I notice it a little.
i also use milk and 2 spoons of peanut butter in mine so that slows down the issue.... plus, it is a new protein for u, maybe after a few more, it will be fine, dont know
