Universal Animal Stak

You Have Potential to be Greater Than You Are

That's why you're in this game. You just gotta tap into it. Animal Stak was designed to help you get the most out of the anabolic hormones you already have pumping throughout your body.*

As a serious lifter, you want to get bigger and stronger. Who doesn't? So you look for every advantage. Essentially the aim of any serious training program is to promote muscle tissue growth by increasing the body's natural production of anabolic hormones, while at the same time, decreasing the production of unwanted catabolic hormones. This is what we call the anabolic advantage. In short, this means more muscle growth and less muscle breakdown. Optimizing your body's levels of naturally occurring anabolic hormones - hormones like testosterone, growth hormone (GH) and IGF-1 - can make a huge difference when it comes to making the gains you want and tapping into the anabolic advantage. These hormones are secreted during a hard resistance training session. Muscle rebuilding essentially takes place due to these important hormonal secretions that arise with balls to the wall training. When you have a hard training session, this however, also results in a rise in unwanted catabolic hormones such as cortisol. What we want to do is increase the output and functionality of the main hormones involved in resistance training and the ways in which to increase their anabolic output, but also limit the role of catabolic hormones. That's what we designed Animal Stak to do - to work naturally with your body to enhance the function of testosterone, growth hormone (GH) and IGF-1.*

The Three Aspects of Hormone Regulation

Testosterone is the primary hormone that interacts with skeletal muscle tissue and as many know, testosterone's role is paramount in muscular development. When it comes to optimizing testosterone levels, there's a couple of things to take into consideration: (1) you'd want to make sure your testosterone levels aren't low - nutritional deficiencies can cause low serum testosterone levels; (2) you'd want to minimize the conversion of anabolic hormones like testosterone to hormones such as estrogen and dihydrotestosterone (DHT); (3) finally, you'd want to make sure that your ratios of "free" testosterone to "total" testosterone are advantageous. Free testosterone is the form of testosterone that exerts the anabolic effects strength athletes are after; it's the stuff that gives you results. By addressing all three issues, you could tap into your body's true potential. We engineered Animal Stak to address all three aspects of hormone management mentioned above, making it a complete natural "test" pack. Animal Stak contains ingredients to help positively impact estrogen and DHT conversion, a natural process. It also includes nutrients that can help increase serum testosterone levels.*

Along with testosterone, growth hormone (GH) may be the most anabolic hormone around. GH also known as somatotropin is naturally secreted by the pituitary gland. Animal Stak works to maximize natural levels of GH, an important hormone for any athlete. Animal Stak contains growth hormone secretagogues that support your body's own natural production of GH. These secretagogues work to trigger the pituitary gland to secrete more GH. Animal Stak is a safe, natural way to help support an increase in GH production.*

Complete Hormone Management Supplement

All in all, Animal Stak is complete. It approaches hormone management from a number of different biochemical perspectives in order to allow you to maxmize size and strength gains. So if you're looking for an alternate route to get the most out of anabolic hormones, and you got everything else in order, then it's time to give Animal Stak a shot.*

Consider "stacking" Animal Stak with either Animal Test or Animal M-Stak for even greater gains.

Goal: Build Muscle

After reading some reviews I was really looking forward to trying this. After a few weeks I didn't notice huge gains, or a huge increase in strength. However, this product allowed me to hold the high level of intensity I like at the gym for longer. This I believe is what lead to the gains. So I didn't notice more strength, but this product is defiantly worth it!

Goal: Increase Strength

This is the real deal. Universal has been in this business a long time and that is why I trust them.
Products like this make my point. I take it about 40 min. before I work out and I can tell a difference.
I have noticed if I get off schedule and take it too late at night I have trouble getting to sleep.
I will continue to use it, because I know it works.

Goal: Build Muscle

Two thumbs up. I take it every morning or 30 minutes before a workout. Even on days when I don't workout, I feel much stronger than I would. This stuff really works. Also, my recovery times have been split in half. I'm NEVER sore, even an hour after my workout. I would recommend this shit to anybody.

Goal: Build Muscle

I have takin this on and off for seven years I have tried alot of stuff. I'm totally in love with this I'm in a bad mood without it. I have a hard time training without it. I do get a few zits from this. And I want to rip off peoples heads sometimes . But the muscle I gained from using this has stayed with me over the years. Stack this with m stak or just a plain old red bull or five hour and work out for hours.
