Here are the three top ingredients found in this pre-workout supplement that make it so effective:

L-Citrulline Dl-Malate

Citrulline Malate1 is derived from watermelons.

It is an important vasodilator, meaning that it helps in opening up your blood vessels.

When it is absorbed in the body, Citrulline is converted to L-Arginine2, an amino acid that increases the levels of nitric oxide in the body.

Taking Citrulline before workout has also been seen to increase the growth hormone by 66.8% after a workout.

Caffeine and L-Theanine

L-Theanine3 is an amino acid derived from great tea leaves.

It helps to improve focus and control.

Caffeine, on the other hand, is a stimulant that keeps up energy while maintaining mental awareness.

Used together, these two ingredients complement each other, one giving you energy and one helping you to control it.

Rhodiola Rosea

This Scandinavian herb is used to combat fatigue.

It also increases your cognitive functions while improving your well-being.

2. Blackwolf Track

Blackwolf Track

Blackwolf Track is a pre-workout supplement specially made for men.

It is designed to give you improved focus, energy, and endurance during workouts.

Sometimes you might be fired up and ready to go during your first workout.

But towards the end of the week, you might be struggling with fatigue, barely making it to the end of your reps.

Taking Track ensures that your workouts are consistent and one as efficient as the other.

The manufacturer recommends that you take a 30g scoop up to three times per day as needed.

You can take this with water or fruit juice.

For the best results, you should use Track for 60 days, combining it with a good diet and regular exercise.

Its ingredients are contained in a proprietary blend called the Blackwolf Power Blend.

Here are the three top ingredients found in this blend that make it so effective:

Vitamin C (Ascorbic Acid)

One of the most common but essential vitamins, Vitamin C, helps to eliminate free radicals that may build up during a workout.

Ascorbic acid also plays an important role in the growth and repair of tissues.

When you lift heavy weights you tear muscles, which the body repairs during recovery.

Vitamin C aids the body in this process.

Whey protein isolate

This ingredient has a high concentration of leucine, an amino acid that aids in muscle recovery.

It is also useful in muscle protein synthesis.

Whey protein5 plays an important role in building up muscle.

Vitamin B12 and B6

Vitamin B6 is important in the creation of red blood cells.

Because it is not produced in the body, we must get it from foods or supplements.

Track contains 5mg of Vitamin B6 per serving.

Vitamin B12 helps to keep the body’s blood and nerve cells healthy.

When blood cells are not working at optimal, you are likely to get weak and fatigued quickly.

Using Vitamin B126 in this formula ensures that your blood cells remain active and healthy during and after your workouts.
