Iron Labs AC8 Xtreme Review

Our Iron Labs AC8 Xtreme Review brings a pre-workout product before us that has a name that is complete nonsense.

Unfortunately, that is the supplement world we live in for most products but it is what is on the inside that matters most.

Since it is one of the cheaper options on the market, we will be interested to see how it can stack up against our top recommended pre-workouts. There are some big and impressive names on there, so how does this compare?

In order to stand out, it needs to be able to do what a pre-workout should. In our eyes, that is something like this:

  • Increase energy
  • Enhance focus
  • Give greater muscle pumps
  • Provide big gains!

Anything less than this and it will not impress. So, let’s start by getting to know it a little better.

Iron Labs AC8 Xtreme Review: Who Makes This Fat Burner?

Iron Labs NutritionIron Labs AC8 Xtreme

This is the UK based company behind the product.

Having reviewed their T-Booster Test Xtreme, we know they are a fan of dropping the E from Extreme!

We also know that they were established in 2009 and later partnered with Euro Nutrition back in 2013. After this, they completely rebranded their product range and now say they only use the most effective ingredients. Something we will prove or disprove soon.

Everything is made in GMP certified facilities and they offer worldwide shipping. A lot of their sales are made through Amazon. This isn’t an approach that all brands go for though. Some believe that it lessens their reputation as listing it there means listing it alongside low-quality products as well.

They have a decent product range with everything from Creatine and metabolism to energy support supplements. We do like that their site is simple but there isn’t a lot of useful information about the products.

Iron Labs AC8 Xtreme Ingredients

This is where we can really see if this is going to be a product worth buying.

The good news early on is that there are no proprietary blends. This means we get to see all the ingredients and dosages. It, therefore, means we can see how effective everything is.

Creatine Monohydrate

A mainstay in pre-workout supplements for a reason, this is a popular ingredient for having a variety of good traits.

You will find it in many of our top recommended pre workouts and as describe, it is often used by athletes to increase power output and lean mass.

So effective and you don’t need to cycle it as Creatine is well researched and considered to be one of the safest ingredients in supplements.

It is the benefits for your muscles that make it so good. It will give them energy and strengthen them after training, this is when their levels usually start to drop. Now you see why it is such a vital ingredient!

Creatine provides your muscles with everything they need to recover faster which also results in greater gains. Growth Factor 1 in your muscle tissue will be increased. This aids the development and growth of the muscles.

The damage caused by exercise is reduced and it is the perfect ingredient for both pre and post workout.

WebMD advises that it is an ingredient that is involved in making the energy our muscles need to function. They also advise that vegetarians and other people with lower Creatine levels seem to get more benefit.

It is one of the most commonly consumed ingredients by bodybuilders and it even has links to aiding testosterone levels as well as cognitive function.

There is a study that proves how it can benefit the body at any time. This talks of how supplementing it during arm flexor strength training led to greater increases in arm flexor muscle strength, upper arm muscle area, and fat-free mass than strength training alone.

The dosage of 3,000 mg is a very good one as well.

Dextrose Monohydrate

A bit of a quick fix here.

It is thought to be useful post workout rather than pre-workout as it can aid recovery. Thought to be a fast-acting ingredient it will help your body to get back to a normal state after a tiring workout.

Dextrose is a form of glucose that has high energy content making it a popular ingredient in these type of supplements.

It is also thought to be useful for muscle growth post workout but more studies are needed to really support this properly.

Our bodies convert it into energy upon digestion and common sources are the likes of oats, honey, and foods high in starch.

It is a useful inclusion, but some of its benefits are still understudied and are based on potential.

The dosage of 2,500 mg is sure to have a positive effect though for energy levels.


It is a naturally occurring amino acid, but in higher amounts can be a bit problematic.

WebMD tells us that it is a nonessential amino acid that is produced in the body.

It is thought to have a few uses in this type of supplement but we do have our reservations. It is linked to potential side effects, although they are minor. Sill, they are inconvenient for the consumer.

Without a whole lot of support behind it, its popularity is a little surprising. When you look at what it is supposed to do, it isn’t the most convincing. Beta-Alanine is believed to help prevent fatigue from setting in and boosts the body’s production of Carnosine.

More of this means your muscles can stay at peak levels for longer.

Vegans and vegetarians will find that supplementing it is a great way of getting more of it into their system as some of the most prominent sources are the likes of poultry, meat, and fish.

We mentioned the side effects and they include a tingling sensation on the skin. It won’t be long before this wears off but it is a bit annoying when you’re in the gym.

WebMD back this up and advise that high doses can cause flushing and tingling.

The dosage of 2,000 mg is a useful amount as it is enough for it to have an effect, just be wary of the tingling.


Another useful ingredient and one that has been included to aid muscle recovery once again. It helps to soothe muscle soreness after a hard workout.

Often used for protein metabolism it has been found to increase your blood levels of the growth hormone. This is also an ingredient that protects you from having a weaker immune system.

Training hard can leave the body vulnerable with a lot of people feeling weaker than usual after. L-Glutamine protects the muscles from depletion, this is especially the case after a tough cardio workout. says that is is only beneficial through supplementation when otherwise deficient, or after prolonged endurance exercise. Vegans, vegetarians and those with low dairy intake will be in particular need of it.

The 2,000 mg is another big amount that will serve the body well.


An antioxidant that is linked to increased blood flow. This, in turn, will aid your performance in the gym.

It is actually a little misunderstood. Because it is found in various energy drinks, some believe it to be a stimulant-like ingredient. The opposite is actually true. Taurine is thought to have a calming effect on the consumer.

This is why it is found in energy drinks, to work against the Caffeine levels and ensure you are still in control.

It can help you to stay relaxed, even when your body is full of stimulants. This makes it a useful ingredient here because of the Caffeine content in this product. It might also help to work against the side effects of Beta-Alanine.

A common ingredient in nootropic supplements because of the above. The main problem though is the lack of human trials. There is some promise being shown from animal studies but we prefer to see further evidence before we can truly get behind any ingredient.

The 2,000 mg included is a generous amount though.

L-Citrulline Malate

Another popular ingredient for pre workouts.

This is because it improves blood flow to the muscles. It achieves this by increasing nitric oxide levels. Derived from the likes of watermelon it is an amino acid that is a clever inclusion.

L-Citrulline has been found to give your workout more power and it even makes sure there is lots of oxygen in your muscles.

It converts in the body into Arginine which aids creatine synthesis. As a result, you will be getting even more creatine in your system. An ingredient saved for the higher quality supplements a lot of the time and the 1,500 mg is a decent amount.


An ingredient that is common in just about every type of supplement.

Arguably the most versatile then. Just about every supplement can benefit from offering an energy boost that is a well-documented benefit from Caffeine. This, as you get to the gym, will really set you up for a good session.

It isn’t just energy that makes it good though. The increased focus means it can really help you make the most of your time in the gym.

Too much Caffeine isn’t great though and you need to be mindful of your daily tolerance. The L-theanine will help to make sure you have a better chance of staying in control and calm but since the larger dose here equates to 400 mg of Caffeine, this is something to keep an eye on.

It is a tactic of many supplements to include a lot of caffeine to mask a poor product. At least Iron Labs AC8 Xtreme contains some useful ingredients as well.

Iron Labs AC8 Xtreme Side Effects

For many of the ingredients, there is nothing to be concerned about.

Even Beta-Alanines tingling-like potential side effects wear off before too long and aren’t the worst type of side effect out there. Although, it can be inconvenient.

400 mg of Caffeine should be well tolerated if you do not consume anymore throughout the day. Our only reservation is the fact that it is a lot in one go.

It would be advisable to work your way up to the larger dosage and build up your tolerance.

  • No proprietary blends

Iron Labs AC8 Xtreme Cons

Iron Labs AC8 Xtreme Review Conclusion

Although this isn’t the best pre workout on the market, it does represent a decent option.

We like that they haven’t been stingy when it comes to dosages, although it would have been nice to see a little less Caffeine being thrown in.

There are enough positive ingredients to make us feel like it is going to have an effect and benefit your workout. The main problem is it doesn’t quite have enough of the top ingredients we would hope for.

The likes of Red Beetroot Extract would really be useful for huge muscle pumps. L-Carnitine would have been good for helping the user to maintain peak levels for longer as well.

To sum up this Iron Labs AC8 Xtreme review, it is probably about one ingredient short of being an impressive ingredient. For now, it will be considered a steady option, but not outstanding.

Since there are better options out there, we recommend that you don’t settle, and go for a product that will really get you the gains you need.
