What's in 4 Gauge

Caffeine Anhydrous

Caffeine is easily the world’s most recognized and popular stimulant, being present in coffee, tea, colas and energy drinks. Its main source is coffee beans (and tea leaves). Anhydrous means it has no water so it provides “pure hit” of caffeine. Studies have shown that caffeine increases fat oxidation, so basically instead of your body solely using glycogen for energy it’ll also use fat stores so you can last longer.

[7. A.E. Jeukendrup & R. Randell, Fat burners: nutrition supplements that increase fat metabolism, Obesity reviews, Vol. 12, issue 10].

Caffeine also increases the product of heat, and reliably increases the state of wakefulness allowing you to stay more focussed in your workouts.

L – Theanine – 200mg dosage

An important amino acid, L-Theanine elevates levels of dopamine and serotonin which control the brains reward and pleasure centres, Apparently L Theanine is the ingredient that provides the calming sensation from drinking tea or green tea. Data suggests it improve mental state and focus, just what you need in the gym!

Creatine Monohydrate – 1000mg

Creatine Monohydrate is always an excellent workout supplement, it increases the amount of water in muscles to promote protein synthesis. However, rather than being used to make gains it has been included in this supplement to improve muscle regeneration and lower muscle fatigue, keeping you fresher and ready to get some more gains!

L – Citrulline DL Malate – 6000mg

This amino acid has been extracted from watermelons, with the aim of your muscles more of that good blood pump. It works by dilating your blood vessels allowing more blood to pass through. Apart from the obvious benefit of bigger, vein-filled muscles it also allows your muscles to have more strength. The optimal dosage for L Citrulline Malate is 6-8g for people who exercise meaning that this pre- workout allows you to get the optimal level for this nutrient for better workouts.

Beetroot Extract – 300mg

This antioxidant supplement is a brilliant source of vitamins and nutrients that is used by athletes and bodybuilders to increase their workout performance. It increases the amount of plasma nitrate which works to have a similar effect as Citrulline Malate by improving blood flow in the body.

Rhodiola Rosea – 100mg

This supplement has been included in 4 Gauge as it is said to help you stay focus and improve your mood essentially getting you in the zone for a workout session.

Acetyl – L – Carnitine – 500mg

Another amino acid, L- Carnitine helps you in two ways, firstly it provides you with energy that helps you to feel energised both physically and mentally for your workouts. The second way this amino acid helps you is by reducing the muscle damage on your body after a workout, allowing for a quicker muscle repair time.  Additionally, is within the optimal level for users who exercise.
