shred a bull review - leanbulking.comAbout Shredabull Untamed

ShredABull Untamed is a fat burner by AD (Anabolic Designs). It’s the sequel to their ‘ShredABull’ fat burner product, at a price of $48.99 for 50 capsule containers (with a serving size of 1 capsule per day).

We prefer fat burners with daily serving sizes of 3-4 capsules; this ensures that your body is always topped up with the key ingredients needed to burn fat. Unfortunately, 1 capsule is likely to only stay in your system for 2-3 hours, leaving you with no benefits for the rest of your day (in our honest opinion).

Anyway, we’ll tell you about the company behind this fat burner before analyzing ShredABull Untamed’s nutrient profile.

At the end of this review, we’ll tell you the results…

Who is AD (Anabolic Designs)?

Anabolic Designs is a supplements company that was founded in 2009. It’s based in the USA and markets a variety of products – from testosterone boosters to fat burners like ShredABull Untamed.

This company seem to be owned by another company called MuscleFoodsUSA.

ShredABull Untamed Ingredients Reviewed

The first thing we noticed about ShredABull Untamed was that it contained 3 proprietary blends. We never like seeing these on a supplement ingredient list, so this immedietaly gets a thumbs down from us (we’ll expand on this below)…

What’s a proprietary blend? 

Simply put, proprietary blends are one of the biggest gimmicks in the supplements industry.

These blends are mixtures of numerous ingredients, allowing companies to hide the dosages of ingredients (as they only provide the overall dosage of the whole blend). As you can see from the ingredient list below, the whole dosage of the ‘Neurostim Blend’ is 495mg. The problem is, you’re not given the exact dosage of caffeine inside.


Ultimately, this increases your risk of side effects, which is a bad thing. Anyway, we’ll take you through each ingredient. By the end of this review, you’ll have a good idea of how safe and effective ShredABull UNTAMED really is.

ShredABull UNTAMED Supplement Facts.

Here’s Everything You Need To Know:


Caffeine is one of our favorite fat burning ingredients as it helps raise your energy levels; this is very useful while you cut calories in order to lose body fat. However, when over-dosed (over 100mg per capsule in a fat burner supplement), then it can cause jitters or energy crashes.

But that’s not the only problem – as ShredABull UNTAMED contains Caffeine in a proprietary blend, no-one knows the exact dosage of this stimulant inside (meaning we don’t know whether it’ll cause any side effects).

As this whole blend is 495mg, there’s a possibility of there being a dosage of over 100mg per capsule – putting you at risk of suffering from jitters and energy crashes.

Whether you’ll suffer from these side effects depends on your tolerance to Caffeine. But as a general rule, we always advise you to consume under 100mg Caffeine per capsule with fat burners – to stay safe.


Also known as DMHA, this stimulant is seen as the perfect replacement for DMAA (which has been banned in numerous countries after causing harmful side effects).

However, it’s not certain whether DMHA is actually safe or works – which is the reason why we’ll be avoiding this ingredient for the foreseeable future.

*Update* Companies have begun to remove DMHA from their products, so this is proof that this stimulant isn’t safe or effective (in our honest opinion).


This is a ‘brain booster’ ingredient that has shown to improve your focus in the gym in numerous studies. While it clearly works, we don’t believe that there’s any need for this as ShredABull UNTAMED contains Caffeine (which has shown to enhance your focus enough for the purposes of a fat burner).

However, we do think that L-Tyrosine can be a key player in ‘non-stimulant’ pre-workouts that don’t contain Caffeine. Also, it’s a key ingredient in Nootropic supplements – but it’s not needed in fat burners; remember that the main purpose of fat burners is to promote fat loss and L-Tyrosine doesn’t really do that.


Cayenne Pepper Extract 

Cayenne Pepper Extract is one of our favorite fat burning ingredients for one reason – it works.

Everyone knows how spicy this chili pepper is and it can make you sweat after eating it. Well, this is exactly how it works to raise your metabolism, which directly improves your fat burning potential.

However, the problem is that it’s contained in the ‘Incinerate Thermo Complex’ (proprietary blend). This means that Cayenne Pepper Extract might not be contained in ShredABull UNTAMED in an optimal dosage (meaning it might not work here).

Higenamine Hydrochloride 

You might not have heard about this ingredient before. But all you need to know is this; Higenamine is extracted from a plant and is believed to promote fat loss.

However, no studies have shown that it actually works (or is safe, in our honest opinion). For this reason, we’ll be avoiding Higenamine for the foreseeable future.

White Willow Bark Extract 

A strange ingredient to add to a fat burner; Willow Bark delivers similar effects to aspirin (reduces headaches, migraines, and muscle pain etc.).

These aren’t key reasons why you’d take a fat burner – ultimately, you want ingredients that are directly going to promote fat loss, such as Green Tea Extract instead.

Gamma-Butyrolactone Ethyl Ester Hydrochloride

Simply put, this is nothing more than a useless ingredient with a fancy name (again, just our honest opinion).

Why? Because studies have proven that Gamma Butyrolactone Ethyl Ester Hydrochloride is ineffective.

But that’s not the only problem here.

The big problem is this; it ingredient might be filling up most of the ‘Incinerate Thermo Complex’, which would make the product partly ineffective too. Ultimately, this is a great example of why we don’t like proprietary blends in supplements.



This is a form of Yohimbe that’s actually a prescription drug in the USA – it’s been banned in numerous countries, such as the UK and Canada after causing harmful side effects (see side effects section below for more info).

We can’t ignore that there have been studies showing that Yohimbe can promote fat loss. But you only have to see the side effects that it’s linked with to know why we choose to avoid Yohimbe when possible.

Ultimately, there’s no reason to risk your health when there are safe and effective options, such as Cayenne Pepper Extract, available.

Thyrocharge Complex

All you need to know about Bovine Thyroid: this is an ingredient that’s only available with a prescription in the UK. It’s shown to affect your thyroid hormone, which isn’t always a good thing.

For this reason, we recommend avoiding this ingredient – especially when it’s part of a proprietary blend and you don’t know what dosage is contained.

As for the Guggul Lipid PE Extract, it’s not proven to do much in any studies.

Black Pepper Extract 

Although black pepper is well-known for making food taste better…it’s more of a bonus ingredient in a fat burner, rather than a key one.

Why? Answer: Because Black Pepper Extract’s main benefit is improving digestion and the absorption rate of other ingredients (due to containing  piperine).

But here’s the problem; to get the most out of this, you need to consume it with ingredients that actually work. You don’t want to improve the absorption rate of ingredients such as Yohimbe, which can cause side effects.

What are the best fat burning ingredients?

Right, we probably seem like we’ve heavily criticized AD Shredabull UNTAMED here, so we’re going to justify our review in this section.

Basically, we’re going to show you which ingredients that are safe and proven to actually help you lose your unwanted body fat – without suffering from any side effects.

In all fairness to AD (Anabolic Designs), they’ve included one of the best thermogenic nutrients (Cayenne Pepper Extract).

However, we’ll list the nutrients that would have raised our ranking of AD Shredabull UNTAMED below:

  • Cayenne Pepper Extract – Cayenne Pepper Extract is one of the most proven thermogenics available. Everyone knows what happens when you eat a hot chili (you begin sweating due to an increase in body temperature). This is exactly how it works to boost your metabolic rate to encourage your body to ‘burn’ more body fat. Just make sure it’s in a clinically effective dosage.
  • HMB– One benefit that all fat burners should offer, is protecting muscle mass. This is because your muscle mass is at risk when you’re in a calorie deficit in order to lose body fat. HMB has shown to help protect muscle mass in clinical studies, but we noticed that only one or two fat burners on the market contain this ingredient.

Shredabull Untamed Side Effects: Is It Dangerous?

ShredABull UNTAMED contains a few ingredients that we’re worried about – Yohimbe, Bovine Thyroid, and DMHA.

Why? Because these ingredients have been reported to cause side effects, which is why we personally avoid them.

In fact, this could be the reason why there have been users on forums claiming that Shredabull Untamed caused sweating.

Ultimately, there are plenty of more beneficial ingredients to promote fat loss, so there’s no need to risk suffering side effects.

Here are the potential side effects of taking ShredABull UNTAMED: 

  • Stomach Upset (Yohimbe)
  • Anxiety (Yohimbe)
  • Nausea (Yohimbe)
  • Bloating (Yohimbe)
  • Headaches (Yohimbe)
  • Rapid Heartbeat (Yohimbe)
  • Increased Thyroid Production (Thyrocharge Complex)
  • Jitters (DMHA)
  • Energy Crashes (DMHA)

ShredABull UNTAMED Results: Review Conclusion

As you can see from the list of potential side effects above, we chose to avoid this pre-workout. Basically, this proves our point about proprietary blends – they’re one of the biggest gimmicks in the supplements industry as companies can fill them with sh*t ingredients (which cuts costs and increases their profit, in our honest opinion).

Not only that, ShredABull UNTAMED contains ingredients known to cause side effects; especially Yohimbe, which we believe to be a potentially harmful nutrient (in our honest opinion). For this reason, we would personally look for other fat burners that don’t contain Yohimbe Bark Extract (such as in our Burn Lab Pro Review).
