Ask any bodybuilder or experienced strength athlete and chances are they already know all about Universal Nutrition's Animal Stak. Half the guys in their gym probably use it or have used it. Ask them to describe just what Animal Stak is, however, and they might need a spotter. That's the kind of product Animal Stak is; it doesn't fall neatly into any preexisting supplement categories. But that doesn't mean it's not a powerhouse of a product. There are good reasons why so many athletes use the Stak.
Animal Stak is a ready-to-use "stack" of supplements and nutrients that all play some kind of a role in building or maintaining muscle. It's similar to a test booster, but it's more than that. Animal Stak's does address testosterone, but also others things like cortisol and estrogen. Take just as directed and use Animal Stak in conjunction with a strength training program. Each jar lasts for one 21 day cycle, you're going to like what Animal Stak can do for you in just 3 weeks.
