GEL30 Caffeine+ Energy Gels with Caffeine by Styrkr - 30g of Carbs - Pack of 12 Running & Cycling Gels with 150mg of Caffeine - for Endurance Athletes - Dual-Carb Formula - GEL30 Caffeine+ 12x Pack

Free Shipping

Why We Love It

Boosts energy levels instantly.
Enhances focus and alertness.
Reduces exercise-related irritation.

Main Highlights

WORLD’S BEST, ATHLETE-APPROVED, ALL-IN-ONE SPORTS FUEL: Styrkr’s GEL30 Caffeine+ energy gel contains a scientifically-researched and athlete-approved mix of carbohydrates (30g), caffeine and L-theanine designed to help all athletes – from enthusiastic beginners to supported pros – go harder for longer. Well-renowned ironmen, cyclists and runners use Styrkr products during training and events because they deliver when it matters most.
MAXIMUM ENERGY BOOST: During intense exercise, carbohydrates are your body’s primary source of energy and more can be absorbed per hour when they come from multiple transportable sources: in this case maltodextrin and fructose (converted to glucose in the liver). Styrkr’s GEL30 Caffeine+ carbohydrate gel incorporates this dual-carb system – and contains 30g of carbohydrates – to help you reach your finish line in the fastest time possible.
MORE POWER, MORE FOCUS: Styrkr’s GEL30 Caffeine+ carbohydrate energy gel also contains 150mg of caffeine to increase alertness, reduce perceived effort and pain, and help you stay focused on the task ahead.
LESS IRRITATION: Styrkr’s GEL30 Caffeine+ carbohydrate gel doesn’t contain L-theanine for fun, it does so because L-theanine increases alpha wave production, promoting relaxation without causing drowsiness. When combined with caffeine, it increases focus and alertness without any irritation.
FEEL THE DIFFERENCE: 60ml energy gel sachet to be consumed directly before or during vigorous activity. Just rip the top, get it down and feel the difference.
