Pre Workout

Compare GYM HIGH pre-workout supplements and training-support products. The range includes caffeinated and caffeine-free formulas, alongside individual products such as beta-alanine, L-arginine and liquid L-carnitine.

Formulas and serving sizes differ. Before choosing, check the current product label for caffeine, ingredient amounts, directions, warnings and suitability. A longer ingredient list or a higher stimulant amount is not automatically a better fit.

How to choose a pre-workout

• Decide whether you want caffeine. Count coffee, tea, energy drinks and other supplements as part of your total daily intake.
• Compare complete servings. Scoop sizes vary, so use the amount listed for one full serving.
• Look for disclosed quantities. Clear amounts make formulas easier to understand and compare.
• Read the directions and warnings. Follow the label for the specific product and do not exceed its stated serving.

Caffeinated and caffeine-free options

The Stacker is the caffeinated option in the range. It is intended for experienced adult users and its current product page lists the serving size, caffeine sources, all active ingredients and the maximum daily serving.

The Stinger is the caffeine-free option. Its current product page lists 12 active ingredients and the amount of each ingredient in a 17 g serving.

Other products shown in this category are not necessarily complete pre-workout formulas. Check each product page to understand whether it is a single-ingredient product, a capsule or liquid format, or a multi-ingredient formula.

Food supplements should not be used as a substitute for a varied, balanced diet and healthy lifestyle.
