Buying Guide

Check stimulant content

Compare caffeine amounts and green tea extracts to match your tolerance and timing to avoid sleep disruption or jitters

Assess amino acid support

Look for BCAAs or EAAs and total amino-acid doses to support endurance and reduce muscle fatigue during prolonged sessions

Prioritize electrolytes for hydration

Electrolyte tablets or sport formulas with sodium, potassium and magnesium help maintain performance in long or sweaty workouts

Consider servings and cost per serving

Compare total servings (e.g., 40–65) to estimate value per use rather than judging by package price alone

Review dietary restrictions and ingredients

Check labels for vegan, gluten-free status and sugar content—zero-sugar options suit those avoiding added carbs
