The Animal series of supplements is expressly designed for the bodybuilder. Animal Stak 2 claims to increase testosterone and muscle gains. Testosterone boosters don’t actually boost testosterone. They work as aromatase inhibitors, which stop testosterone from converting to estrogen. This increases the concentration of testosterone. The product description for Animal Stak 2 does not list clinical studies proving any benefits of the ingredients in the supplement. There are testimonials for Animal Stak 2, but none of the testimonials reveal how the supplement works as a standalone product. Instead, the reviewers stacked the supplement with other products. The Animal series is designed to be stacked together, so the cost could get extraordinary.

Product Features

First and foremost, the ingredients in Animal Stak 2 are not designed to improve weight loss. As a matter of fact, some users report increasing body weight due to water weight and bloating. Another side effect reported by one user was skin breakouts. The user claimed the breakout may not have been associated with Animal Stak 2, but he did not list any other supplements he was taking in conjunction with the supplement.

Animal Stak 2 is not a single supplement. The product is packaged in individual packs with multiple supplements in each pack. There are 21 packs in each container. After three weeks, the user needs to cycle off the supplement for one week. The body tends to get used to supplements rather quickly, so we assume the cycle off is to maintain optimal effects.

The formula is created to be stacked with other Animal products, but some users report stacking it with Jack3d and other stimulants. This could be very dangerous as these formulas are not designed by the same company.

The supplement is expensive, retailing for around $60. When stacked with other supplements, the cost can double or triple. This is much more expensive than many potential users can afford.
