Gnarly Maximus Pre Review - LeanBulking

About The Product

Gnarly Maximus Pre is a pre-workout supplement made by Gnarly Nutrition. It comes in 30 serving containers at $37.95 on their website, in 1 flavor – Lemon Lime.

Who are Gnarly Nutrition? 

Gnarly Nutrition are a supplements company that creates all natural products – we prefer natural products, as they’re less likely to cause side effects, so this is a great thing.

This company markets a range of supplements, mostly protein powders to BCAAs and pre-workouts like Gnarly Maximus Pre. They also sell another pre-workout called Gnarly Pump, which we’ve also reviewed.

Gnarly Maximus Pre Ingredients Explained

This is the most important section to find out how effective a supplement really is. Put it this way – if an supplement is filled with ineffective ingredients or incorrect dosages, then it won’t work. It’s as simple as that.

So we’ll analyze each ingredient inside Gnarly Maximus Pre; to show you whether it’s worth trying or not.

Here’s Everything You Need To Know:


Also known as Branched Chain Amino Acids, there are three of them – Leucine, Isoleucine, and Valine.

They’re shown to enhance muscle protein synthesis (growth) and is often contained in protein powders. For this reason, we believe it’s more beneficial to consume BCAAs after a workout, not before.

BCAAs aren’t expensive to buy seperately, but you can easily consume enough through a well-planned diet (they’re found in many foods such as meats). If you’re a vegetarian, this could benefit you though.

Citrulline Malate 

Citrulline Malate is one of our favorite pre-workout ingredients. It’s shown to enhance muscle pumps, as it’s able to raise your nitric oxide levels.

However, it’s only proven to work in dosages between 6,000mg-8,000mg. This shows us that Gnarly Nutrition hasn’t done enough research here, as they could’ve simply added the extra 1,000mg needed to make it an optimal dosage.


We have very mixed opinions on Beta-Alanine. Basically, it’s shown to improve muscular endurance, but it also causes paresthesia (see side effects section for more info).

Glutamine is an amino acid that’s not actually needed by your body. Basically, it’s believed to promote muscle protein synthesis (growth), but studies have shown that it has no effect on muscle gains.

Simply put, Glutamine offers no benefits to immediately benefit your workout in a pre-workout supplement.

Asian Ginseng Root Powder 

Also known as Panax Ginseng, this is great for boosting your testosterone levels. For this reason, it’s more suited to a testosterone booster supplement.

But it causes no side effects so there’s nothing negative with having Panax Ginseng in here. It just won’t be very effective as you only take a pre-workout supplement once a day (Panax Ginseng works best when dosages are spread throughout the day).

Ginger Root Powder

There’s nothing special about this ingredient. It’s the same stuff you add into your food or tea, and it can improve digestion.

However, it’s not going to improve your gym session.


We’re impressed that Gnarly Nutrition has dosed Caffeine perfectly in Gnarly Maximus Pre – most companies add too much Caffeine in (over 200mg per serving), which can cause jitters.

With this perfect dosage of Caffeine (180mg), you’ll experience heightened energy, strength, and focus in the gym. We give credit where credit is due, so great job by Gnarly Nutrition here.

Side Effects 

Gnarly Maximus Pre is only likely to cause you one side effect – paresthesia.

What’s paresthesia? 

Paresthesia is a tingling on the skin of your face and body. Basically, it’s not harmful, but it can be distracting when you’re trying to focus on smashing your gym session.

Here’s the potential side effects from taking Gnarly Maximus Pre:

  • Paresthesia – tingling on the skin of your face, chest, hands, fingertips and toes (Beta-Alanine)

Gnarly Maximus Pre Review Conclusion

We believe that Gnarly Maximus Pre’s 3 star rating is a fair decision. It contains some of our favorite pre-workout ingredients (Citrulline Malate and Caffeine), but also contains Beta-Alanine which can cause paresthesia – however, some people don’t mind paresthesia too much, so this is a subjective decision on this ingredient).

One great thing about Gnarly Maximus Pre is that it has a great dosage of Caffeine (180mg) – we recommend consuming a maximum dosage of 200mg in a pre-workout to avoid jitters and energy crashes.

But more bad points about Gnarly Maximus Pre include:

  • Citrulline Malate underdosed at 5,000mg (optimal dosage is at least 6,000mg)
  • Asian Ginseng Root Powder more suited to a testosterone booster
  • Glutamine not shown to work in any study
  • We prefer taking BCAAs after a workout, instead of before

For this reason, we believe there are better pre-workout supplements available for you to try.
