I don't think they sell Animal Test anymore. Someone might actually. I've just started taking Animal Stak 2. It's too early to tell if it's any good or not.
I've been using the Animal Pak for about a month now & like it...my only complaints are the number of tabs & the size of some of the tabs. I don't really feel much difference but when you look at all the aminos/vits/minerals, you can't help but be impressed. I've used Animal M-Stak before & was reasonably impressed with the results I got.
