There’s only one person who can scream at me voluntarily: Coach Greg Doucette.

On his YouTube channel, he’s been teaching mere mortals (or fellow circles, as he calls us) the ins and outs of fitness and exercising.

“Train Harder Than Last Time” – Coach Greg

Coach Greg is an IFBB Pro Bodybuilder, Master of Kinesiology, Guinness World Record Holder for multiple lifts, Fitness coach, and well-known YouTube personality.

Oh, and not to forget master chef with his famous Ultimate Anabolic Cookbook 2.0 that has completely transformed the dieting game.

Also, after reviewing the Pre-Workout 2.0, Pre-Pump, and Hardcore Stim, “Mad Pre-Workout Scientist” can be added to the list (click for review).

With his new venture, HTLT Supplements, he’s set to take over the supplement with high-quality, premium fitness supplements.

The mission is to help you train harder than last time and get the results you’re looking for.

I’ll review the HTLT Supplements to find out if it’s the real deal.

In this article, I’ll review GO2 Max to find out if it’ll help you have More Endurance Than Last Time.

Grab your favorite popcorn machine, pop some kernels, and find out if HTLT GO2 Max is next on your supplement list.

Ingredients in HTLT GO2 Max

HTLT GO2 Max does not contain any proprietary blend, which means there are no hidden ingredients, and all quantities are known.

This is a good thing because it’s always best to know what we consume. Six properly dosed ingredients to significantly improve your cardio(vascular) sessions.

I’ll explain every component in detail below:

Vitamin B

  • 125 mcg of B9 (31% DV)
  • 500 mcg of B12 (20833% DV)

Vitamin B plays a vital role in metabolism, where they help carbs, proteins, and fats convert into energy. Besides turning food into energy, they’re needed in many places inside our bodies to keep our cells functioning properly. They also help to create DNA

Some examples are:

The vitamins can expand the blood vessels, which increases blood flow, and allows for a better pump while working out. They’re also used to create neurotransmitters: dopamine, serotonin, and GABA (gamma-aminobutyric acid).

They can increase energy, help the metabolism, reduce fatigue, improve mood, promote healthy skin, etc.

In GO2 Max, they’re primarily added to offset potential side effects from NMN.

73.98 mg of Sodium (3% DV)

Sodium is an essential mineral. Taking sodium before a workout can help you work out longer by increasing blood volume and improving blood flow, which means more nutrients and oxygen goes into your muscles.

Sodium is also crucial for proper water and mineral balance in your body and is essential for nerve function and muscle contractions.

Sodium is necessary for endurance athletes because much sodium is lost during training.

400 mg of Nicotinamide Mononucleotide (NMN)

NMN naturally occurs inside all living beings and is a precursor for Nicotinamide Adenine Dinucleotide (NAD+).

NAD+ is a vital coenzyme that we need on a cellular level to survive. Below are some of the things NAD+ does (simply explained):

  • Vital role in our metabolic process transforms fats and glucose into energy.
  • Protects against aging by controlling DNA damage (the leading cause of aging).

Studies have shown that NMN can significantly improve overall aerobic capacity, likely due to better oxygen utilization by the skeletal muscle.

70 mg of ElevATP

ElevATP is a patented ingredient that increases ATP production in our bodies (the primary energy source of our muscles), which helps us to increase work capacity and power output.

For cardiovascular purposes, this means you can go harder for longer. For weight training, this means being able to do more sets and repetitions.

This allows us to improve cardio, build more muscle, improve strength, and over time help us to achieve better body composition and performance.

Clinical studies have backed the effectiveness.

5 mg of Black Pepper Fruit Extract

Black Pepper Extract is used in GO2 Max because it improves the absorption rate of other ingredients.

It also has a thermogenic effect that can boost energy by increasing internal body temperature.

Experiences with HTLT GO2 Max

Experiences with HTLT GO2 Max are astonishing, and people state it’s a “blessing.

Starting from the first dose, they notice a significant improvement in their cardio workouts or high-intensity sports like martial arts.

They feel more energized and can continue longer without being out of breath or winded. Endurance improves tremendously, power output increases, and there’s less time needed to recover between intense sets or rounds.

A nice benefit for people trying to lose weight is that they can burn more calories in the same amount of time, helping them to get more shredded and fit than last time.

An important note is that many people use two pills instead of the recommended dose of one.

Price of HTLT GO2 Max

Price of HTLT GO2 Max

HTLT GO2 Max is priced at 39,99 dollars. This makes the price per capsule around $1.

I believe the price is justified since it’s an effectively formulated supplement that also holds safety into account. The potential side effects of NMN are offset by Vitamin B.

NMN is not a cheap substance, especially in a 400 mg per capsule dose.

Is HTLT GO2 Max Worth It?

Train Harder Than Last Time – Screaming Coach Greg

When looking for supplements to improve your workout performance, the things that come to mind are pre-workouts, fat burners, BCAAs, etc.

A supplement like GO2 Max is not a well-known option. Nonetheless, I believe HTLT GO2 max can make a real difference in performance and endurance in high-intensity activities or cardio sessions.

It has a unique formula with NMN and ElevATP for better performance and endurance, Vitamin B against side effects (and other benefits described above), Sodium to stay hydrated, and Black Pepper Extract to increase absorption of the other ingredients.

Studies on NMN show a significant increase in aerobic capacity, which can likely be even better with GO2 Max. Experiences sure show that it works as intended.

If you’re looking to upgrade your aerobic capacity, improve your high-intensity activities, or become better at your sport, I recommend giving HTLT GO2 Max a shot.

This (legal) supplement might take your performance to the next level.
