The Advanced Science of Post-Endurance Repair.
The SiS Beta Fuel Recovery is a premium, dual-source recovery solution specifically engineered for athletes who engage in high-intensity or prolonged endurance exercise (90 minutes or more). Unlike standard recovery shakes, Beta Fuel Recovery uses a precise 1:1 ratio of Maltodextrin and Fructose. This combination is designed to simultaneously replenish both muscle and liver glycogen stores, ensuring you are fully fueled for your next session.
Each serving delivers a massive 60g of dual-source carbohydrates and 30g of high-quality Whey Protein. The addition of probiotic cultures helps facilitate protein digestion and nutrient absorption, minimizing gut distress while maximizing muscle repair. It is designed to be mixed with 500ml of water and consumed within 30 to 60 minutes post-exercise to kickstart the recovery window.
Available Flavors
The 1.5kg resealable pouch is available in four distinct, smooth-mixing flavors designed to be palatable even after total exhaustion:
Chocolate: A classic, rich cocoa profile that is widely considered the "gold standard" for recovery drinks.
Vanilla: A lighter, creamy option that is excellent if you prefer a less intense sweetness after a hard effort.
Salted Caramel: Features a sophisticated sweet-and-salty balance that can be particularly satisfying for "salty sweaters" who crave sodium post-ride.
Strawberry: A refreshing, fruit-forward alternative that provides a crisp finish compared to the heavier dessert-based flavors.
Key Features
Dual-Source Glycogen Recovery: The 1:1 Carb ratio is scientifically proven to restore liver glycogen significantly faster than maltodextrin alone.
High Protein Load: Provides 30g of Whey Protein per serving to support muscle protein synthesis and structural repair.
Gut Health Support: Includes 250mg of BC30™ Probiotics to enhance nutrient uptake and support digestive comfort.
Complete Electrolyte Profile: Replenishes the Sodium, Potassium, and Magnesium lost through heavy perspiration.
Informed Sport Certified: Rigorously tested for banned substances, making it a safe and trusted choice for competitive and professional athletes.

✅ Why This IS For You
High-Volume Trainers: If you have less than 24 hours between hard training sessions, the dual-source recovery is essential for ensuring your energy stores are topped up.
Intense Endurance Athletes: Specifically designed for those who have "emptied the tank" during 90+ minute rides, runs, or triathlons.
Muscle Maintenance: The 30g protein dose is higher than many competitors, making it ideal for athletes looking to maintain lean muscle mass during heavy training blocks.
❌ Why This May NOT be for you
Short/Light Sessions: For rides under an hour, the SiS REGO Rapid Recovery may be a more cost-effective choice as the advanced dual-source carbs are less critical.
Weight Management Focus: With approx. 370 calories per serving, this is a heavy-duty fuel source; if you are in a caloric deficit, a lower-calorie protein-only shake might be preferred.
Dairy-Free Athletes: This formula contains Whey Protein (Milk); those with lactose intolerance or vegan diets should look at the SiS REGO Cherry Juice or plant-based alternatives.
