4 Gauge Pre-Workout Ingredients

  • Caffeine Anhydrous – 150 mg
  • L-Theanine – 200 mg
  • Creatine Monohydrate – 1,000 mg
  • L-Citrulline DL- Malate – 6,000 mg
  • Red Beet – 300 mg

  • Acetyl-L-Carnitine – 500 mg

Caffeine anhydrous

Caffeine anhydrous is a dehydrated form of caffeine, available in a powdered form. Because it doesn’t have water, it’s a highly concentrated form of caffeine.

Just a teaspoon of this ingredient is the equivalent to 28 cups of coffee. It’s used in this formula to slow down the use of glycogen as a source of energy, directly the body to use fat instead.

It’s supposed to increase power, strength, and endurance for longer periods of time by strengthening muscle contractions, according to research published in the European Journal of Sport Science.

According to Dr. Anthony Dugarte, “I would not recommend using [a] product [with this] amount of caffeine, in this case dehydrated, [as it] may be harmful. A safer pick-me-up would be simply having a cup of coffee prior to working out. For those that aren’t coffee drinkers or do not wish to consume that much caffeine, tea is another option. Black tea has somewhere in between ¼ – ½ the amount of caffeine when compared to coffee.”

4 Gauge Pre-Workout ingredients creatine

Creatine monohydrate

Creatine monohydrate is a modified version of creatine, which is a molecule the body produces. It stores high-energy phosphate groups in the form of phosphocreatine, which releases energy to aid in cell function during stress.

This causes strength increases after creatine supplement. It can also benefit the liver, muscles, brain, and bones. It can also be found in food, mostly eggs, meat, and fish.

Creatine monohydrate is a supplemental form of this natural chemical, according to the Journal of the International Society of Sports Nutrition.

L-Citrulline DL-Malate

L-Citrulline DL-Malate is citrulline with an added malic acid component. Malate, or malic acid, is a naturally occurring organic compound found in a variety of fruits, though it is most commonly used as a food additive or preservative. Citrulline one of the most popular pre-workout ingredients found in many supplements.

It has been shown to improve muscle endurance and strength, as well as aerobic performance. It is also shown to deliver improved absorption and is twice as effective at raising nitric oxide levels when compared to l-arginine. When combined with citrulline, malic acid has been shown to promote better food absorption and higher bioavailability.

However, some studies also suggest that malic acid may have potential benefits on its own including supporting pain management and increased energy. It is also often added to skincare for products for its potential exfoliating properties.

The DL-Malate version tends to be the preferred nootropic as it may increase organized and nitric oxide levels while also potentially increasing energy output offers a one-two punch that is popular among athletes and bodybuilders.

Red beet

Red beet is the vegetable. There are several health benefits of beets. However, you’ll get the most benefit from eating the vegetable raw compared to getting it and supplement for. They are a good source of essential nutrients such as B vitamins, copper, magnesium, potassium, iron, and manganese.

They help to improve your stamina, improve the way your brain works, detoxify your liver, and better equip your body to fight chronic health problems, according to Nutrients.

4 Gauge Pre-Workout ingredients

Rhodiola Rosea

Rhodiola Rosea comes from the Rhodiola plant. Though it’s used to address many conditions, there’s not enough research to support it as an effective treatment option for any. It’s considered an adaptogen, so it helps the body to adapt to and resist various stressors.

It is also used to improve athletic performance, improve sexual function, reduce recovery time after workouts, and address heart health issues such as high cholesterol and irregular heartbeat.

It’s thought to work by helping protect the cells from damage, regulating heartbeat, and improving learning and memory.

It’s worth noting, however, that none of these effects have been studied in humans, and additional research is needed to confirm any health benefits, according to BMC Complementary & Alternative Medicine.

A study published in Phytomedicine showed Rhodiola to be an effective adaptogen.


Acetyl-L-Carnitine is an amino acid or a building block of protein that is naturally produced in the body which helps the body produce energy. It is used for a variety of mental conditions, including age-related memory loss, thinking problems related to alcoholism, poor circulation in the brain, facial paralysis, and cataracts.

The body can convert L-Carnitine over to acetyl-l-carnitine and vice versa, but no one knows what is the effects of acetyl-l-carnitine are from the chemical itself from the L-Carnitine it can make or from some other chemical made along the way.

It’s best not to substitute one form of carnitine for the other.

4 Gauge Pre-Workout ingredient

Coconut Water Powder

Coconut Water Powder is a powdered form of coconut water. It helps keep the body hydrated, provides key nutrients, and offer a substitute for sports drinks. It’s found in young coconuts and provides a good source of vitamin C, several important nutrients, and fiber.

3 4 Gauge Pre-Workout Reviews

  • Taste is not very pleasant
    Rey (Verified Purchase)

    I have a hard time drinking it because of the taste. Also, I have to use 3 to 4 scoops in order for it to kick in. There is no pump.

  • Not for me
    Tim Statza (Verified Purchase)

    Was excited to try 4 gauge but it was waste of money. This did not work for me. There was no jitters but also no pumped feeling, maybe a little more energy but hard to notice anything. The taste was horrible and left an after taste. It not worth choking it down. I ended up throwing it out after first use.

    • Rey

      Same experience for me. I have to use 3 to 4 scoops to try and get a good pump before my work out.
