Product Description

Science in Sport Black Friday Packs are live! 

The brand behind the world’s first isotonic gel has evolved into a full suite of performance enhancing products. From the OG Isotonic GO Gels to the advanced Beta Fuel lineup, they have some of the most effective fueling products available.

Black Friday Pack Details

25 Isotonic Gels for $25 - A dollar per gel for SiS's legendary easy-to-digest format. Mix of caffeinated and non-caffeinated so you can fuel strategically without carrying water. Isotonic means they absorb fast without the gut bomb..

12 Energy Oat Bars for $20 - Real oats, real fuel, less nonsense. These go down easy when traditional energy bars turn your stomach. Sustained energy that can go the distance.

12 Beta Fuel Drink Mix for $20 - $1.67 per serving of 80g carbs. This is SiS's high-performance formula used by WorldTour teams for high-carb intakes. Multiple transport pathways mean maximum absorption when you're pushing hard. 80g in one bottle is as easy as it gets.

10 REGO Clear Recovery for $20 - Accelerate recovery with protein, carbs, and electrolytes in a smooth, clear format. Don't get along with the thick classic recovery shakes? No problem. Mix it within 30 minutes post-effort and actually be ready for tomorrow's session.

12 Protein Bars for $15 - 20g of protein in a format that doesn't taste like cardboard. Real recovery nutrition between sessions or when you need something substantial that fits in your pocket.

18 Hydro+ Tablets for $18 - Drop one in your bottle for light electrolyte support without carbs. Perfect for easy days, recovery rides, or when you're fueling separately.

Beta Fuel Packs - All 12 for $20

Beta Fuel - The 40g dual-source carb gel that pro athletes love. With a proven 1:0.8 ratio, these gels are incredibly effective at fueling your hardest days. Choose Orange for classic citrus, Strawberry & Lime for a bright fruit combo, or a lightly sweet Neutral for zero flavor and pure function.

Beta Fuel + Nootropics - 40g carbs plus cognitive support from 200 mg of caffeine and nootropics in Apple or Lemon Lime. Brain and body fuel in one gel for when you really need to get locked in.

We want you to love the nutrition you purchase from The Feed. We also know that sports nutrition is personal - a flavor, texture, supplement, or fueling product that works perfectly for one athlete may simply not be the right fit for another.

That’s why we offer our Always Happy Promise.

If you try a nutrition or consumable product and you’re not satisfied with it, let us know within 30 days of delivery and our Athlete Experience team will work to make it right.
