Ingredients Label
Active Ingredients
Caffeine
Caffeine is the most widely-used stimulant in the world.
It increases energy levels and alertness, but can also positively impact physical performance when used at higher doses (1).
An effective dose is usually between 200-500mg, and varies from person to person.
Kigelia Africana
Kigelia Africana is an African tree, which yields an odd-looking fruit.
This fruit contains a compound called DMHA – very similar to the banned ingredient DMAA, both in structure and effects.
These effects include increased energy, and an uplift in mood and motivation.
We don’t know how safe it is yet, due to a lack of research.
White Tea
White tea is a great source of green tea catechins.
These compounds are great for heart health, and provide strong fat-burning effects (3).
Who Takes It?
Athletes looking for a strong energy-boost for their workouts will enjoy using Giant Rush.
How to Take
Mix 1 scoop with cold water, and consume 20 minutes before your workout.
You may take Giant Rush alongside a stimulant-free pre workout for enhanced effects.
Side Effects
Caffeine can trigger rapid and/or irregular heartbeat when taken at high doses.
Kigelia Africana extract may have additional side-effects, which are not yet known.
Pros
- Two powerful stimulants are used
- Can be added to non-stimulant pre-workouts for extra effects
Cons
- Contains no other ingredients to assist with other parts of your workout
- Kigelia Africana extract is not well-researched, and could have negative side effects
Conclusion
Giant Rush is a basic, yet powerful high-stimulant pre-workout.
The likeness of Kigelia Africana extract to DMAA makes for both an exciting but somewhat worrying formula. This is due to strong positive effects, but the possible risk of harmful side effects that may come with it.
With Giant Rush, you can expect a big boost in energy and mood, but not as much in terms of focus, pumps, or physical performance.
For best results, try pairing Giant Rush with a stimulant-free pre-workout.
