While most pre-workout supplements rely on caffeine to promote high energy levels, intensive pre-train is designed to provide long-lasting energy boosts without stimulants. The supplement is primarily aimed at athletes of all skill levels, although all sports enthusiasts and fitness enthusiasts can use it.

The supplement is designed to combat fatigue, boost endurance, increase endurance, and give you more muscle pumps. Unlike other pre-workouts, Intensive Front End provides fast, long-lasting results.

What does intensive pre-workout contain?

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

While some ingredients present in the supplement directly boost your performance, some increase the effects of the main ingredients, like piperine. Here is everything you need to know about the ingredients in pre-train intensive and their benefits in light of the science:

Citrulline Malate

A combination of non-essential amino acid and malate, Citrulline Malate is vital for the production of energy in your body. Citrulline has vasodilator properties and therefore helps increase muscle pumps. It dilates your blood vessels during exercise, which improves blood flow to the muscles and helps you get bigger muscle pumps.

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

Citrulline malate also helps with the increased oxygen content in your muscle cells. Each serving of Pre-Train Intensive 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 the muscles while you exercise or train.

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

Betaine anhydrous

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

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

Glycerol monostearate

An emulsifier widely used in baking, glycerol monostearate is beneficial for muscle hydration. Due to its ability to improve endurance, glycerol monostearate may help improve aerobic and anaerobic performance. Each serving of Intensive Pre-Train contains 1 g of glycerol monostearate.

L-arginine AKG

An essential amino acid, L-arginine acts as a precursor to nitric oxide and therefore produces vasodilator effects. L-arginine alpha-ketoglutarate is a complex compound that works synergistically with other nitric oxide precursors to enhance its production.

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


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

L-tyrosine supplementation helps with weight loss while preserve lean muscle mass. You get 1 g of l-tyrosine in each serving of Intensive Pre-Train.


A potent endogenous antioxidant, taurine supports muscle recovery and relieves cramps after training. It prevents muscle damage, fight fatigue, and soothes muscle pain, allowing muscle fibers to heal quickly. The muscle support effects are especially common in people performing weight lifting exercises.

Taurine is essential for muscle growth and function. It also has specific nootropic effects and helps improve 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 provides increased focus, alertness and mental clarity for 5 hours after ingestion. You get 100 mg of EnXtra® in each serving of Intensive Pre-Train.


A building block for connective tissue, Gluconolactone occurs naturally in your body and so-called cognitive function helps. The natural compound removes fog from the brain and provides nootropic benefits than caffeine. Each serving of Pre-Train Intensive 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 increases cardio-respiratory endurance. Each serving of Intensive Pre-Train contains 300 mg of KSM-66.
