Stacker2 Stim Junkie is a supplement in capsule form for anyone looking for a focus and energy kick before training.

Pre-Workout Boosters Briefly Explained

The market for training boosters is huge – but the basic principle is always the same: a powder mixture, mixed about 20–30 minutes before training. Differences lie in three dimensions: the amount of caffeine (from caffeine-free to high-dose), the pump ingredients such as citrulline and arginine, and the ingredients for taste and focus. The caffeine content per serving is stated on the label – it is the most important selection criterion, especially if coffee or energy drinks are also consumed during the day. Those who train late or are sensitive to caffeine will find the right alternative in stimulant-free pump products.
