By Best Nutrition - Singapore · · 2 min read

Quick answer
Essential Amino Energy is a lighter option with about 100 mg of caffeine per two-scoop serving plus amino acids, making it suitable as a mild pre-workout or an afternoon pick-me-up. A full pre-workout such as C4 Original has more caffeine and performance ingredients for a stronger effect. Choose Amino Energy for flexibility and C4 for maximum intensity.

When to choose Amino Energy
Amino Energy is a good fit if you train after work and do not want a heavy caffeine hit, or if you want something to sip instead of a sugary drink in the afternoon. You can adjust the dose from one to three scoops to suit your tolerance.
