Why it made the stack
Key takeaways.
6 g of citrulline and 2.5 g of betaine match the amounts used in research, which many pre-workouts skip.
150 mg of caffeine is about a strong cup and a half of coffee. Enough to help, without the 300 mg jolt of some brands.
Caffeine does most of the work. The other ingredients have smaller, less consistent effects.

What the research says
What the evidence shows.
Caffeine
The International Society of Sports Nutrition finds caffeine reliably improves endurance and many kinds of strength and power work. Benefits usually start around 3 mg per kg of body weight, about 200 mg for a 150 lb person.

Citrulline and betaine
The NIH reviews both. Some trials show small gains in reps or power, others show none. They're safe at these doses, but don't expect a big difference.
