At MySport.lv, you’ll find a wide selection of SISI products — from energy gels and hydration tablets to protein bars.

SISI products are developed and tested in collaboration with world-class athletes, including professional cycling teams and Olympic-level competitors. Their quality is confirmed not only by athlete feedback but also through rigorous laboratory testing.

Key advantages:

• Free from artificial sweeteners and preservatives

• Informed-Sport certified — each batch is tested for banned substances

• Effective formulas for both endurance and strength training

• Convenient packaging for workouts, races, or daily use

To make your choice easier, MySport.lv offers a wide variety of targeted solutions for different types of training and sports:

• SISI GO Energy Gels – Fast-acting carbohydrates without caffeine. Perfect for long endurance efforts like marathons or extended cycling sessions.
• SISI Hydro Tablets – Effervescent electrolyte tablets to prevent dehydration during hot conditions or intense training.
• SISI Protein20 Bars – High-quality protein bars with low sugar content, ideal after training or as a healthy snack.
• SISI Beta Fuel Range – A high-carb drink designed for endurance athletes, optimized for efficient energy absorption during long training sessions.

Using sports nutrition correctly is essential to achieving optimal performance and avoiding early fatigue or muscle breakdown.

At MySport.lv, many athletes prefer to combine multiple SISI products into a smart nutrition plan. Here’s an example of a training day plan:

Before training (30–60 min):

• 1x SISI GO Energy Gel

• 500ml of water with 1 SISI Hydro tablet

During training (90–180 min):

• 1x Isotonic Gel every 30–45 minutes

• Sip SISI Beta Fuel drink every 45–60 minutes

• 1–2 Hydro tablets dissolved in water for longer sessions or hot weather

After training (within 30 min):

• 1x Protein20 Bar or a protein recovery drink

• Additional 300–500ml of water

Adjust this plan based on your body weight, intensity, and climate. Pro tip: test your strategy in training, not on race day!
