Universal Nutrition Animal Test Review

Universal Nutrition Animal TestYou’ve got to give Universal Nutrition Credit for Animal Test. This is a formula over 5 years old, and they haven’t had to change. It. Each serving is 4,000 mg of active ingredients… No other big brand has been this bold when making a test booster!

The only real downsides are, price, quantity, and yes – competition for the best natural test booster has picked up.

So how effective is Universal Nutrition’s Animal Test? Let’s go over the ingredients to learn more…

Universal Nutrition Animal Test Ingredients

Urtica Dioica

Urtica Dioica is the scientific name for Stinging Nettle, which is used for a variety of purposes. This is the first listed ingredient on Universal Nutrition’s Animal Test, and therefore is likely the largest dosed ingredient in the test booster blend.

So, does Stinging Nettle Increase Testosterone?

The simple answer, no. While Stinging Nettle is the primary ingredient in Animal Test, there isn’t any valid research stating that Stinging Nettle does in fact increase total testosterone.

However, there are benefits to Stinging Nettle. They include:

  • A significant reduction in inflammation.
  • Reduction in DHT resulting in increased free-testosterone
  • Reduces aromatase activity

These three benefits aren’t ultra-significant for muscle growth on their own, however they are important for longevity and vitality. The reduction in inflammation can reduce bodily stress, help the healing process, and generally clear up a lot of health issues that you may drudge through with every day. The DHT reduction on the other hand may protect your prostate, which is good considering you only have one of them. Lastly, the anti-aromatase activity means that it reduces your production of estrogen, which can help put your body into a better testosterone-estrogen ratio. This is a good thing.

Cissus Quadrangularis

Like Stinging Nettle, Cissus Quadrangularis is lacking on research regarding this ingredient raising testosterone levels in men.

So does Cissus Quadrangularis Raise Testosterone?

We don’t think so. But, like Stinging Nettle above, there are other significant benefits to this herb. They include:

  • An increase in serotonin levels.
  • Reduced Joint Pain and Improved Mobility
  • Potential fat-loss aide

Based on these perceived benefits, we can understand why Universal Nutrition included Cissus Qudrangularis in Animal Test.

That’s because anything that raises serotonin (mood) is going to be attributed to an increase in testosterone. Likewise, improved joint mobility will as well be attributed to increased vitality related to testosterone.

Do we think it’s bad, that this ingredient doesn’t actually raise testosterone? Well, it’s not exactly honest, but these are legitimate benefits that can’t be denied. We still like this product, just thus far it may be better to frame this product as a muscle builder and vitality support rather than a ‘test booster’.

Polygonum Cuspidatum

More commonly known as Japanese Knotweed, Polygonum Cuspidatum is a potent source of the antioxidant resveratrol.

Does Polygonum Cuspidatum, and its active ingredient resveratrol increase testosterone levels?

According to animal studies (mice) it does. That, along with many other potential performance increases. You can learn more about that over on Nutrient Journal.

Despite this, Polygonum Cuspidatum is not the bona fide test boosting ingredient that we had been hoping for in Animal Test.

Agaricus Bisporus

Agaricus Bisporus is the scientific name for the white button mushroom. After researching this ingredient, it quickly became apparent that this ingredient doesn’t raise testosterone. Rather, White button mushroom reduces the conversion of testosterone to estrogen.

Though, to get this benefit, the recommended dose is often high. Simply put, much more than you could obtain via pill form supplementation.

With that being said, we’re hoping for the best here, and hopefully the small dose is potentiated by other anti-aromatase ingredients in Animal Test.


Hesperetin, taken from citrus fruit, appears to be another anti-aromatase ingredient. Unlike other ingredients, Hesperetin may be effective in doses as low as 1 mg.

Anti-estrogen appears to be the main trend with Universal Nutrition’s Animal Test. And, with all of these ingredients working together, over time its easy to assume that the effects will add up.

However, it will take time to purge out excess testosterone while all this anti-aromatase activity buffers its re-introduction. Likewise during this process, testosterone should theoretically be building up to a significant level.


Yohimbe is a popular and semi-controversial ingredient. In the supplement industry, it can be used as a stimulant, fat burner, erectile support, and a test booster. However, does it work as a test booster?

It doesn’t appear to raise testosterone to any significant level.

Rather, Yohimbe is associated with testosterone due to its energy increasing and erectile boosting effects, which can be confused with testosterone enabled vitality.

Arachidonic Acid

We really aren’t going to discuss Arachidonic Acid in detail. Why? Because we question how ethical this ingredient is. Arachidonic Acid’s purpose as a supplement is to cause inflammation in the muscle. Inflammation, is not a healthy thing. Nor is it something to purposely impose through supplementation. For that reason, we have nothing more to say.


Grapefruit contains compounds that act in an anti-aromatase fashion, like the majority of ingredients in Universal’s Animal Test.

Since it is the second to last ingredient, we can assume that it is in the 2nd smallest quantity.


As you likely know, Bioperine aids in nutrient uptake. It’s a good ingredient to see added on.

Animal Test Review Round-Up

Animal Test by Universal Nutrition is through and through an anti-estrogen supplement. Due to this, it may raise testosterone as testosterone builds up due to not being easily converted into estrogen or DHT.

Overall, Animal Test has a lot of benefits that you will notice over time. They may be mistaken for increased testosterone.

Universal Nutrition recommends that you take Animal Test for 1-2 straight cycles. During this time, you can take any other Universal Nutrition products that you’d like. During your off-cycle, you can take M Stack to maintain gains.

Overall, we enjoyed this product a lot. However, to us it would be better put to use when combined with an actual testosterone boosting supplement. In this way, you can reduce estrogen while blasting testosterone to the roof!
