Animal Stak is a comprehensive hormone booster. It boosts your natural testosterone levels AND your natural growth hormone (GH) levels while keeping your estrogen levels from rising. Animal Test is a straight testosterone booster and the power of this test booster is different than that contained in Animal Stak. Animal Test also contains Arachadonic Acid, a powerful omega-6 fatty acid that enhances inflammation in muscle fibers during training. On top of that, Animal Test contains Yohimbe Bark Extract to assist in testosterone boosting.
