First Endurance Tryout Pack
Dial in your fueling strategy with First Endurance's science-backed fueling system. This bundle pairs your hydration and carbohydrate needs in one simple pack, so you can take out the guesswork and focus on the work at hand.
What's Inside
- 3x First Endurance Liquid Shots (Kona-Mocha, Vanilla, Wild Berry)
- 2x First Endurance EFS Drink Mix Singles (Lemon Lime, Fruit Punch)
Why This Bundle Works
EFS Drink Mix: Your Foundation – This is your primary hydration and fueling source delivering 30g of optimally balanced carbohydrates plus a clinically effective dose of all 5 electrolytes—sodium, potassium, chloride, calcium, and magnesium. The complete electrolyte profile also provides industry-leading cramp prevention during critical moments. The isotonic formula means faster absorption without GI distress, while the light flavor profile prevents taste fatigue during long efforts.
Use one serving (or more if needed) in approximately 500-700ml of water every hour and continue as needed throughout your session.
Liquid Shot: Your Fast-Response Fuel – When efforts spike or energy flags, Liquid Shot delivers 110 calories and 30g of fast-acting carbohydrates in an easy-to-consume isotonic formula. Unlike traditional gels, there are no gums or thickening agents to slow absorption—just instant fuel that empties from your stomach fast and gets to working muscles when you need it most.
Take one gel every 30-60minutes depending on fueling needs.
Better Together – This is exactly how First Endurance designs their products—complementary, not redundant. EFS keeps you fueled and hydrated throughout your effort. Liquid Shots give you the additional calories and electrolytes you need for surges, climbs, or when you're starting to fade. No ingredient overlap, no GI complications, just comprehensive nutrition that works as a system.
