Universal Nutrition have been working hard on creating a number of bodybuilding supplements and products, and one of them is Animal Stak.
It’s an anabolic vitamin formula which promotes recovery, strength, and testosterone production.
In this review, we’ll cover some of the more frequently asked questions about Animal Stak. Such as, what are the benefits of this product? Does it have side effects? How good are the ingredients? And most importantly, what results can you expect?
Let’s find out!
Pros and Cons of
Okay, here are the pros and cons of Animal Stak by Universal Nutrition. It contains some ingredients that help with libido and testosterone, but there are just as many, if not more useless ingredients that have no effects whatsoever.
What’s worse, this product contains ingredients such as Tribulus Terrestris. Which is notorious for its negative side effects on the male prostate.
Lastly, most of the ingredients within Animal Stak are a part of proprietary blends. In other words, you have no idea how much of each ingredient you’re getting.
- Contains Vitamin D3 – a great ingredient for testosterone (but it’s a low dose)
- Uses Fenugreek which is good for boosting libido
- Contains Tribulus which causes enlarged prostate in some men
- Most of the ingredients come in proprietary blends
- Uses DIM which in high dosages converts testosterone into estrogen
- Not safe to take long-term – you have to cycle Animal Stak every 3 weeks
Animal Stak is a vitamin formula with blends of various ingredients that are claimed to boost testosterone.
Here are the claimed benefits for Animal Stak:
- Support Testosterone Levels in Athletes
- Optimizes Strength and Performance
- Enhances Output of Test and GH through Natural Means
- Enhances Muscle Recovery and Repair
Now, even for the best testosterone boosters, these are some very ambitious claims.
So will Animal Stak be able to hold up to these promises? Or is it just a marketing trick? We’ll soon find out!
Dosage | How To Use
Here’s how you should take Animal Stak:
For the first 3 weeks, take one serving (1 pak) daily. When training, take it 30 minutes before exercise. On rest days, take it between your meals.
This product should be cycled – you should take it for three weeks, then take one week off.
Is Cycling Safe?
Okay, this looks like a good way to take a product. You take it once per day and that’s it. However, the only problem we have here is the “cycling” part.
Every natural testosterone booster is safe to use long-term, which brings up the question; “Is Animal Stak safe?”
That’s a great question, and we’ll be sure to cover it in the “Side Effects” and “What Users Say” sections.
But first, let’s see the ingredients inside Animal Stak. This will ultimately tell us how good, and safe this product is.
When you look at the vitamins and minerals in Animal Stak, you see that there aren’t many of them. We only have Magnesium, Zinc, Vitamin B6, and Vitamin D3 as the vitamins and minerals.
But this isn’t the only problem with this product. In fact, these ingredients are the only good thing about Animal Stak, because the rest of the product contains proprietary blends with tons of different ingredients which don’t show their dosages.
We have “Pro Testosterone Complex,” “Growth Hormone Support,” “Anti-Aromatase Complex,” “Hormone Amplifying Blend,” and “Restorative Support Complex” as proprietary blends inside Animal Stak.
Why Proprietary Blends Don’t Work
Each blend of Animal Stak is targeted towards a specific goal, as their names suggest. But the problem is, none of these blends show the dosage of each ingredient inside. In a nutshell, you have no idea how effective these ingredients are, or whether they’ll work at all.
A supplement that contains a proprietary blend means something shady is going on behind the curtains. These blends are usually made by companies to make more money and reduce the cost of the manufacturing.
By adding ineffective dosages disguised as blends with fancy names, they trick their customers into believing they got something groundbreaking. While in fact, they got an expensive and usually ineffective product.
Best testosterone boosters on the market contain no proprietary blends. They display each ingredient and its dosage clearly for you to see.
Vitamins and Minerals
- Vitamin B6 – helps regulate numerous functions inside the body, including hormone regulation. It’s a good addition if you’re lacking it in your diet.
- Magnesium (As Oxide) – good for muscle and nerve relaxation, also plays a role in testosterone production. However, Animal Stak contains the poorest form of magnesium – oxide. Simply put, magnesium oxide is not accepted well by your body, meaning you won’t experience its full benefits. What’s worse, it’s known to cause people to have frequent trips to the bathroom – I don’t know about you, but I don’t feel like going to the toilet every 5 minutes.
- Zinc (As Oxide) – Good ingredient for boosting low testosterone, but just like magnesium, it comes as zinc oxide, which is the worst form of zinc.
- Vitamin D3 – Perhaps the most important ingredient for boosting testosterone. Studies show around 3,000IU+ of Vitamin D3 daily is the optimal dosage for increasing testosterone. With its 1,000IU, Animal Stak doesn’t even come close to that.
Pro Testosterone Complex (Proprietary Blend)
While this blend is called a “Pro Testosterone Complex,” only a few ingredients actually target testosterone levels. Other ingredients only boost libido, and some of them are even known for their negative side effects.
Have a look:
- Tribulus Terrestris – Not only an ineffective ingredient, studies also link it to prostate enlargement in men.
- Longjack Extract Complex – An Ayurvedic herb, it’s known for boosting libido in men. Ineffective at boosting testosterone though.
- Fenugreek – This is a great ingredient, it’s shown to boost both testosterone and libido in healthy men. However, as its a part of a proprietary blend, we can’t tell how much of fenugreek is inside, which means its effectiveness is questionable.
- Stinging Nettle Root – It reduces the number of sex hormone binding globulin, which directly benefits your testosterone levels. Not as good as Vitamin D3 or DAA, but still a great addition to a test booster.
- Maca Extract – Maca has been used by men for thousands of years for increasing sex drive and libido. It has no effects on testosterone levels though.

Growth Hormone Support (Proprietary Blend)
- Arginine Complex (HCL, ArginoCarn, and Acetyl-L-Caritine Arginate Dichloride) – Arginine isn’t what we’d expected to find in a testosterone booster, because it’s a pre-workout ingredient. However, this isn’t the worst thing about it. See, Arginine is shown to have poor absorption rate orally, making it a useless ingredient in Animal Stak.
- Mucuna Pruriens – Studies link it to improvement in sperm quality in men.
- SuperSerum™ – We can’t tell what this serum is because it doesn’t show what ingredients are inside
- Sustamine™ – Same as SuperSerum. This is a shady policy by Universal Nutrition, it looks like they don’t want to show what they put in their product.
- Alpha GPC – It provides some cognitive benefits, and it also improves endurance in athletes.
Anti-Aromatase Complex (Proprietary Blend)
- Polygonum Cuspidatum Root (Resveratrol) – Found in red wine, Resveratrol is linked to benefits such as improved blood flow and heart protection. It’s a good general health ingredient, but has no effects on testosterone.
- Calcium D-Glucarate – This one is actually great for reducing estrogen in men. It’s shown to help excrete excess estrogen from the body.
- DIM – It helps in the conversion from estrogen to testosterone. However, in larger doses, it does the complete opposite. Since we don’t know how much of DIM is inside this proprietary blend, it could be either beneficial, or detrimental to your testosterone levels.
Hormone Amplifying Blend (Proprietary Blend)
- L-Carnitine Fumarate – an amino acid that can help burn fat if you’re deficient in it. However, most people aren’t deficient since we get plenty of carnitine from fish and red meat.
- AgmaPure™ (Agmatine Sulfate) – It’s a metabolite of L-Arginine which is shown to have some cardiovascular health benefits.
- Glycine Propionyl L-Carnitine HCl – Studies link it to improvement in erections and blood circulation in men.
- Quercetin -Contains anti-inflammatory and anti-oxidative properties which improve symptoms of an inflammed prostate.
- Astaxanthin – It’s a reddish pigment naturally found in algae and it’s what causes certain species of fish to have pink or red color. As for its benefits, research suggests it helps improve fertility in men.
- Bioperine – This is the same as black pepper extract, it helps with the absorption of other ingredients in Animal Stak.
Restorative Support Complex
- Milk Thistle Extract – Great for your liver, helps with flushing toxins out from your body.
- Astragalus – An herb shown to help with diabetes.
- Ashwagandha – An adaptogen and libido enhancer, Ashwagandha will increase your sex drive and make you feel less stressed.
- Na-R-Alpha Lipoic Acid – A potent anti-oxidant which in high enough doses, help the body get rid of free radicals. However, since it’s within a proprietary blend, we have no idea how much of the ingredient is inside.
- Coenzymes Q10 – It’s a molecule found in mitochondria which plays a role in energy production in the body.
While most users didn’t report any serious side effects from taking Animal Stak, you should be careful with Tribulus Terrestris. When taken long-term, this ingredient could aggravate your prostate.
So unless you want to go to your doctors to examine your prostate, be smart about your use of Tribulus Terrestris.
People reported other side effects:
- Stomach Pain
What Others Say
“Proof was in the numbers. The product advertises the following: “doubles testosterone and increases free testosterone while decreasing Sex Hormone Binding Globulin (SHBG) (the compound that binds to testosterone to keep it in the unusable state), as well as increasing IGF1 levels.”
I had baseline blood work done prior to taking this product. I went through three cans, then reevaluated whereby testosterone levels were a few months later. My total testosterone actually decreased by 23% and Sex Hormone Binding Globulin (SHBG) increased by a few points. This product was taken in conjunction with a solid well rounded nutritional plan, decrease in long distance running, and increase in weight training.
I am not sure what to make of it…but this product certainly did not help, and will cease taking it.” – Mike (Amazon Customer)
“Gave me slightly higher quality workouts and helped me push myself through two plateaus. One last year one this year. If you are looking for a boost check this out. If you are looking for a huge increase quickly, this product will not give you that.” – David E. Maurer (Amazon Customer)
“I didn’t notice much of a difference. I followed the instructions by the book, trained hard, and ate right. I’ve noticed a change from other comparable higher priced products so it might be a “you get what you pay for” lesson. Or I might be a non-responder.” – kona9988 (Amazon Customer)
Universal Nutrition have tried to make Animal Stak an “all-in-one” supplement that boosts testosterone, general health, as well as physical performance. A jack of all trades, if you will.
However, they have failed at doing so, primarily because most of its ingredients are a part of proprietary blends. As a result, you don’t know how effective these ingredients are, or whether they’ll work at all.
What’s worse, Animal Stak uses Tribulus Terrestris and DIM. These ingredients aren’t only ineffective, they also cause negative side effects in some men. Such as man boobs and enlarged prostate.
For these reasons, Animal Stak isn’t a product we’d recommend. It’s simply not effective, nor safe enough to take the risk. There are far better options out there.
