Universal Nutrition Animal Stak Review | Natural Testosterone Booster

Ever wonder why girls don’t build as much muscle as compared to their male counterparts? It’s because of the male hormone called testosterone. This hormone is present in abundance in males while females have estrogen, the female hormone.

If you’ve been working your ass off in the gym but can’t see results, it might be because of a lack of testosterone. Test is also responsible for your sex drive and plays a key role in the development of male reproductive organs.

It also promotes secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. Men need a healthy amount of testosterone in their bodies to be functioning at their optimal levels.

Universal Nutrition Animal Stak Review | Natural Testosterone Booster

Animal Pak has a big list of ingredients. All the ingredients on the label aren’t just any other ingredients. They have been proven to work for the reasons they are included in this supplement. Animal Stak has one of the biggest ingredient lists in its respective category. It follows a ‘kitchen sink’ strategy when it comes to including all the natural testosterone boosting ingredients.

1. Vitamin B6, Magnesium, Zinc, Vitamin D3

These are the natural testosterone boosting ingredients. If you have low testosterone levels, it might be because you’re not getting these nutrients from your diet. Supplementing with these ingredients can get you back on the right track.

2. Pro-Testosterone Complex

Animal Stak contains a big dose of 1500mg of testosterone boosters. The pro-testosterone complex helps with elevating your testosterone levels. Tribulus Terrestris extract, LongJack extract, fenugreek, stinging nettle root, maca extract help with natural testosterone release and support.

3. Growth Hormone Support

GH support (1500mg) consists of natural GH boosters and support agents. Arginine Complex and Immunolin help with the release and support of GH. ArginoCarn supports growth & repair of neurons, supports brain-to-muscle connection, cognitive function and memory and can even enhance fat burning.

Humanofort helps support natural testosterone and growth hormone levels and decrease recovery time. Mucuna pruriens is added for its ability to elevate the production of l-dopa, an amino acid that converts into dopamine.

4. Anti-Aromatase Complex

Calcium D-Glucarate and Diindolylmethane are aromatase inhibitors (300mg). These ingredients restrict the estrogen production in your body. These ingredients are important since testosterone and estrogen levels in your body are inversely proportional.

5. Hormone Amplifying Blend

Animal Stak has 500mg of cortisol inhibitors. Stress and cortisol can block the testosterone production in your body. This blend helps this from happening. Hormone amplifying blend has a long list of ingredients to take care of all the aspects of cortisol production.

6. Restorative Support Complex

Only a few other supplements in this category on the market have a restorative support complex (500mg). This complex helps with the recovery after workouts and your immunity levels. This concludes the long list of ingredients.

How To Take It

Animal is very straightforward with how they want you to take this supplement. They have laid out the directions on the container itself:

Take one pack daily for 3 consecutive weeks. On training days, take it 30 minutes prior to exercise. On non-training days, take it on an empty stomach, between meals. For best results, cycle this product following a schedule of three weeks on and one week off.

Pros Of Animal Stak

2. Natural Way Of Boosting Your Testosterone And GH

3. Increase In Strength And Endurance

With its long list of ingredients, Animal Stak can help you in improving your strength and endurance. The ingredients in this supplement also help in minimizing the catabolic stress response, supporting sexual health and boosting overall immune system function.

Cons Of Animal Stak

1. Proprietary Blend

The quantities of the ingredients in the complexes are hidden under the ‘proprietary blend’ label. We cannot tell exactly in what amount an ingredient is present in the product. Universal Nutrition can use this to their advantage.

2. Underdosed Ingredients

Since we know the total amount of ingredients present in a complex, we can guess the amount a specific ingredient is present in the complex. We can make out ingredients like L-Carnitine, arginine, citrulline, etc. are underdosed.
