How Does It Work?

4 Gauge Pre-Workout Review

4 Gauge makes you workout-ready in the following ways:

  • Boosts Energy Production
    4 Gauge contains a combination of caffeine and l-theanine, which aren’t just beneficial on their own, but also have a synergistic effect. Caffeine is a natural stimulant that increases activity in the nervous system and promotes energy metabolism. However, it can cause you to feel shaky and lead to energy crashes. L-theanine promotes alpha brain wave production and helps smooth out the undesired effects of caffeine. For this reason, the combination of caffeine and l-theanine is often called ‘’smart caffeine’’
  • Increases Blood Flow
    It contains nitrates that help widen your blood vessels, causing more blood to flow through them. This ensures proper supply of oxygen and nutrients to the muscle tissues. Nitrates also help in lowering blood pressure and regulating your heartbeat during an intense workout. 
  • Provides Important Electrolytes
    Electrolytes are minerals found in the blood and other body fluids that carry an electric charge. They are required for muscle contraction and the maintenance of optimal fluid levels inside and outside of cells. They also regulate your blood pH levels, reduce muscle breakdown, and prevent fatigue. 4 Gauge contains a blend of electrolytes that make up for the lost minerals and minimize exhaustion during your workout.
  • Reduces Oxidative Stress
    Exercise leads to the breakdown of muscle cells, which triggers the release of inflammatory cytokines in the body. While short-term inflammation is essential for muscle regeneration and repair, chronic inflammation can cause muscle soreness and long-term muscle damage. 4 Gauge contains various polyphenols that help reduce tissue inflammation and post-workout muscle soreness. 

Key Ingredients in 4 Gauge Pre-Workout Powder

Below is the complete ingredient list of 4 Gauge.

  • L-Citrulline DI-Malate – 6000mg
  • Creatine monohydrate – 1000mg
  • Acetyl l-carnitine – 500mg
  • Red beetroot extract – 300mg
  • Coconut water powder – 300mg
  • L-theanine – 200mg
  • Caffeine Anhydrous – 150mg
  • Rhodiola Rosea Powder – 100mg

L-Citrulline DI-Malate 

L-citrulline DI-malate is a combination of the amino acid l-citrulline and the salt of malic acid, malate. It is preferred over l-citrulline as it helps improve the bioavailability and absorption rate of the amino acid.

  • L-citrulline is derived from watermelons and helps improve weight training and HIIT performance.
  • It boosts nitric oxide production, which makes your muscles look bigger and fuller.
  • L-citrulline has been shown to increase stamina and energy levels by promoting ATP synthesis.
  • Plus, it helps reduce post-workout muscle soreness and aids muscle recovery.

A clinical trial was conducted on 22 patients with vasospastic angina to study the effect of l-citrulline on endothelial dysfunction and lipoprotein oxidation. They were given 800mg of l-citrulline daily for eight weeks. Their blood nitrogen oxide levels, lipid profile, and other parameters were measured before and after the treatment. The study showed that l-citrulline helped improve endothelial function by increasing nitric oxide production and reducing oxidized LDL [1].

Creatine Monohydrate 

Creatine is an amino acid found in red meat and seafood. It is one of the most well-researched supplements for improving workout performance. It has a wide range of benefits, such as:

  • Increasing muscle mass, improving cognitive functions, and reducing fatigue.
  • It helps increases cell hydration and boosts endurance and stamina.
  • Additionally, it aids in muscle recovery and helps prevent muscle cramps.

A placebo-controlled clinical trial was conducted on 25 healthy male volunteers to study the effect of creatine on body mass and muscle strength. The treatment group was given creatine supplements daily for 9 weeks, while the control group received a placebo. They were asked to perform strength training workouts during the treatment. The muscle mass for both groups was measured using bioimpedance spectroscopy. By the end of the study, it was found that the treatment group had a higher muscle mass than the control group [2].

Acetyl L-Carnitine 

Acetyl-l-carnitine (ALCAR) is a derivative of the amino acid l-carnitine, which is mainly produced in the liver, brain, and kidneys.

  • ALCAR passes through the blood-brain barrier more readily than l-carnitine and increases synaptic neurotransmission in the brain.
  • It plays a key role in fatty acid metabolism and regulating mitochondrial processes.
  • It helps boost energy levels, increases muscle strength, and reduces nerve pain.
  • Additionally, it helps alleviate mood, improves memory and thinking skills, and controls blood sugar and cholesterol levels. 

A systematic review and meta-analysis of 37 randomized, placebo-controlled clinical trials was conducted to study the effect of l-carnitine on body composition and weight loss. Online databases were searched up, and studies till January 2019 were included in the analysis. The meta-analysis showed that l-carnitine helped reduce BMI, fat mass, and body weight better than placebo [3].

Red Beet Root Extract 

  • Beetroot contains nitrates, which help increase blood circulation in the body.
  • It is high in bioactive compounds, including polyphenols, which help reduce oxidative stress and inflammation
  • Beetroot helps improve muscle efficiency, strength, and stamina, which enables you to work out for longer.
  • It also helps reduce the risk of heart disease and certain types of cancers. 

A double-blind, placebo-controlled clinical trial was conducted on 9 male volunteers to study the effect of nitrates on oxygen cost during training. On two separate 3-day periods, the volunteers were either given 0.1mmol/kg sodium nitrate or 0.1mmol/kg sodium chloride (placebo). They were asked to perform a fitness test on a cycle ergometer during both treatments to assess their oxygen utilization. The study showed that sodium nitrate helped improve oxygen utilization among the treatment group [4].

Coconut Water Powder 

  • Coconut water is often referred to as “nature’s sports drink’’ as it is a great source of essential vitamins and minerals.
  • It helps boost your workout performance by replenishing lost electrolytes during your workout.
  • These electrolytes help in the transmission of electrical signals between the brain and muscles and facilitate proper muscle contractions.
  • Additionally, they help reduce blood pressure and prevent headaches. 

A clinical trial was conducted on male rats to study the effect of tender coconut water (TCW) on oxidative stress. The rats were given a fructose-rich diet to induce oxidative stress in insulin-resistant, hypersensitive rats. They were given 4ml/100g body weight of TCW daily for 3 weeks. Their systolic blood pressure, glucose levels, lipid profiles, and other parameters were measured during and after the treatment. The study showed that TCW improved insulin sensitivity, reduced blood pressure, and had an antioxidant effect on the rats [5].


  • L-theanine is an amino acid mainly found in tea leaves. It increases the production of alpha brain waves and helps calm down your nervous system without causing any drowsiness.
  • It helps boost energy levels and cognitive functions, such as focus, attention span, and memory.
  • Additionally, it has been shown to promote weight loss, boost immunity, and reduce symptoms of depression and anxiety.

A double-blind, placebo-controlled clinical trial was conducted on 60 patients suffering from Schizophrenia to study the effect of l-theanine on anxiety symptoms. The participants were either given 400mg of l-theanine or a placebo daily for 8 weeks. The outcomes were analyzed through various anxiety and neurocognitive tests. The study showed that l-theanine helped reduce anxiety and improved general psychopathology. Moreover, it was found to be safe and well-tolerated by the volunteers [6].

Caffeine Anhydrous 

Caffeine anhydrous is a dehydrated form of caffeine that is commonly used in workout supplements.

  • It helps build muscle strength, improves muscle contraction, and boosts endurance.
  • It helps in the production of various neurotransmitters, such as dopamine and norepinephrine.
  • In addition, it helps increase concentration and boost energy levels by slowing down glycogen depletion. 

A single-blind, placebo-controlled clinical trial was conducted on 8 male cyclists to study the effect of caffeine and coffee on endurance. The cyclists were either given caffeine (5mg/kg), coffee (5mg/kg caffeine), decaffeinated coffee, or a placebo. After one hour, they were made to perform 30 minutes of steady-state cycling, followed by a 45 min time trial cycling. The study showed that both caffeine and coffee helped improve endurance better than decaffeinated coffee and placebo [7].

Rhodiola Rosea Powder 

Rhodiola rosea is a flowering herb mainly found in Asia and Europe.

  • It helps improve mental and physical resilience and alleviates mood.
  • It helps boost workout motivation, improves cognition, and regulates heartbeat.
  • Additionally, it helps improve workout performance and reduce muscle damage by reducing inflammation.
  • Moreover, it is known to promote anabolic processes, improve muscle strength, and reduce post-workout fatigue and pain

A randomized, placebo-controlled clinical trial was conducted on 57 volunteers to study the effect of Rhodiola rosea on major depressive disorder (MDD). The participants were either given Rhodiola rosea, sertraline (standard treatment), or a placebo daily for 12 weeks. The outcomes were measured through Hamiltonian Depression Rating and Clinical Global Impression Change scores. By the end of the study, it was found that both sertraline and Rhodiola rosea helped reduce depression symptoms. However, Rhodiola rosea had fewer side effects and was better tolerated among the participants [8].
