Crazy Nutrition Intensive Pre-Train Pre-Workout Supplement Review

Developed by Crazy Nutrition, Intensive Pre-Train is a pre-workout that eases fatigue and provides you with an extra boost of energy during workouts. The supplement contains a well-crafted blend of 19 clinically studied ingredients, all of which have been proven to possess ergogenic properties.

While most pre-workout supplements rely on caffeine to promote high energy levels, Intensive Pre-Train is formulated to provide long-lasting energy boosts without any stimulants. The supplement primarily caters to athletes of all skill levels, although all gym-goers and fitness enthusiasts can use it.

What makes Intensive Pre-Train stand out among other pre-workouts on the market is its ability to help you achieve your best performance without impacting other aspects of your health. Most pre-workout supplements on the market flood your body with hefty doses of stimulants that have serious side effects on your cardiovascular health. Although Intensive Pre-Train contains caffeine, the dosage is not high enough to cause over-stimulation.

Intensive Pre-Train by Crazy Nutrition is all you need to reclaim your confidence in the gym. The supplement is designed to combat fatigue, boost endurance, increase stamina, and give you bigger muscle pumps. Unlike other pre-workouts, Intensive Pre-Train provides quick and long-lasting results. With Intensive Pre-Train, you no longer rely on coffee or strong energy drinks to keep fatigue at bay during workouts.

What Does Intensive Pre-Train Contain?

Intensive Pre-Train by Crazy Nutrition boasts 19 health-boosting ingredients, all of which work synergistically to improve your focus, boost energy, and prevent fatigue, thereby allowing you to perform better.

While some ingredients present in the supplement directly boost your performance, some augment the primary ingredients’ effects, such as piperine. Here’s all you need to know about the ingredients present in Intensive Pre-Train and their benefits in the light of science:

Citrulline Malate

A combination of non-essential amino acid and malate, citrulline malate is vital for energy production in your body. Citrulline boasts vasodilatory properties and therefore helps increase muscle pumps. It dilates your blood vessels while exercising, thereby improving blood flow to muscles and helping you get bigger muscle pumps.

The vasodilatory effects of citrulline malate are due to its ability to convert into arginine, another non-essential amino acid responsible for nitric oxide production, which causes your blood vessels to dilate and your smooth muscle tissue to relax.

Citrulline malate also helps increase oxygen content in your muscle cells. Each serving of Intensive Pre-Train comes with 7g of citrulline malate in a 2:1 ratio.


Another essential amino acid, beta-alanine, helps balance pH levels in your muscle tissue during exercise. The ergogenic effects of this compound come from its ability to increase carnosine levels in muscles while you exercise or train.

Carnosine is a compound formed from histidine and beta-alanine. It is required for the normal functioning of muscles as it reduces acidity in the muscles during high-intensity exercise. Each serving of Intensive Pre-Train comes with 2.5g of beta-alanine.

Betaine Anhydrous

A naturally occurring chemical in your body, betaine anhydrous, promotes muscle strength by keeping muscle cells well-nourished. The performance-enhancing effects of betaine anhydrous are particularly noticeable in men due to its ability to boost testosterone levels.

The chemical improves endurance and thereby enables muscle growth and greater muscle strength. Each serving of Intensive Pre-Train comes with 1.8g of betaine anhydrous.

Glycerol Monostearate

An emulsifier widely used for baking, glycerol monostearate is beneficial for muscular hydration. Due to its ability to improve endurance, glycerol monostearate can help boost both aerobic and anaerobic performance. Each serving of Intensive Pre-Train comes with 1g of glycerol monostearate.

L-arginine AKG

A conditionally essential amino acid, l-arginine acts as a precursor of nitric oxide and therefore produces vasodilative effects. L-arginine alpha-ketoglutarate is a complex compound that works in synergy with other nitric oxide precursors to improve its production.

It adds to the effects of citrulline malate to promote NO production and ease fatigue associated with strength training. Each serving of Intensive Pre-Train comes with 1g of l-arginine alpha-ketoglutarate in a 2:1 ratio.


A non-essential amino acid, l-tyrosine, is responsible for producing enzymes, certain hormones, and neurotransmitters. It facilitates communication between nerve cells, which improves focus, increased alertness, and greater mental clarity during workouts. It also boosts muscle protein synthesis and plays a structural role in muscles.

The supplementation of l-tyrosine helps lose weight while preserving lean muscle mass. You get 1g of l-tyrosine in each serving of Intensive Pre-Train.


A powerful endogenous antioxidant, taurine supports muscle recovery and alleviates cramps after workouts. It prevents muscle damage, combats fatigue, and soothes muscle soreness, allowing muscle fibers to heal quickly. The muscle-supporting effects are particularly prevalent in people performing weight-lifting exercises.

Taurine is essential for both muscle growth and function. It also has specific nootropic effects and contributes to improved focus during exercise. Each serving of Intensive Pre-Train comes with 1g of taurine.


EnXtra® is a botanical ingredient that amplifies the effects of caffeine. Although, it can provide the same nootropic effects without caffeine. The component offers increased focus, alertness, and mental clarity for 5 hours after ingestion. You get 100mg of EnXtra® in each serving of Intensive Pre-Train.


A structural component for connective tissues, gluconolactone occurs naturally in your body and purportedly contributes to improved cognitive function. The naturally-occurring compound eliminates brain fog and provides nootropic benefits as caffeine. Each serving of Intensive Pre-Train comes with 400 mg of gluconolactone.

KSM-66 (Ashwagandha Extract)

A patented full-spectrum ashwagandha extract, KSM-66, improves cognitive function, alleviates stress, promotes strength, and boosts cardio-respiratory endurance. Each serving of Intensive Pre-Train comes with 300mg of KSM-66.

In addition to the ingredient mentioned above, Intensive Pre-Train contains optimal doses of essential vitamins and minerals, such as iron, vitamin C, niacin, riboflavin, thiamine, folic acid, biotin, and vitamin B6.

Additionally, the supplement contains complementary ingredients like BioPerine that maximize the absorption rate of other ingredients. Intensive Pre-Train also contains 200mg of caffeine per serving.
