Liquid Shot gets its name because it contains no gelling agents, which is something you may find in a , well, a gel shot. That is key, according to First Endurance, because gelling agents can slow down your digestion and absorption. And if you’re slurping down one of these energy shots during competition, you want it in your bloodstream now. The liquid consistency makes it easier to swallow as well.

EFS stands for Electrolyte Fuel System, and First Endurance offers one of the most advanced systems for racing nutrients available. The list of victories by First Endurance athletes at grand tours, Ironman triathlons, ultra-running races, even the Olympics, says a lot for the quality and innovations the company has achieved.

One five-ounce EFS Liquid Shot-enough for several servings during a race- gives you 400 high quality calories, over 1,500 mg of electrolytes and 1,000 mg of amino acids.

EFS Liquid Shot is available in a handy rsealable, refillable, fully recyclable, five-ounce flask and in 30 ounce refill bottles. I like that. The flasks are easier to use on the fly and cause less waste, and the larger 30 ounce bottle is practical and economical.

You can get EFS Liquid Shot in any flavor you like as long as it’s vanilla. My wife, who will only eat a certain vanilla bean-flavored brand of energy gel during exercise, took one taste of Liquid Shot and ran off with my entire supply.- O. Mattox

 FAST FLASK
While racing the Ironman world championships last fall, I needed 300 calories and 1,000 milligrams of sodium during each hour during the bike leg to stay fueled and combat the electrolyte-draining effects of the heat. One flask of EFS Liquid Shot delivers 400 calories, 100 grams of carbohydrates, more than 1,500 mg of electrolytes, and 1,000mg of amino acids like leucine and l-glutamine, which help reduce muscle damage. It’s more liquid than a gel, so it goes down easy on the fly. It tastes good too-sweet but not cloying.

New EFS Liquid Shot
Team Astana used First Endurance products in their dominating 2008 season, and we recently got ahold of the new EFS Liquid Shot. When we first grabbed it, it seemed like over-kill, until we tried it. Imagine how many gels you go through on a four- to six-hour ride. Three…five maybe? Well, now you can substitute that with 400 calories, 1500mg of electrolytes and 1000mg of amino acids. Even better, it is re-usable and refillable and 100-percent recyclable. The EFS Liquid Shot makes a lot of sense and is a welcome addition to the world of gel-pack technology.

First Endurance EFS Liquid Shot
This lightly sweetened energy concentrate (available only in vanilla flavor) with a creamy consistency is easier to swallow and digest than gel, especially in cold weather when gels tend to thicken. We liked the no-mess closable spout that lets you take as much as needed per workout. Each refillable flask has 400 calories, over 1500mg of electrolytes and 1000mg of amino acids.

Procycling Reviews EFS Liquid Shot
Many of the First Endurance sponsored riders have been integral to the process of developing the new EFS or (Electrolyte Fuel System) “liquid shot”- a gel-like drink for competition use that packs a huge 400 calories and more than 1,500mg of electrolytes into just 130ml. I cracked open a bottle for a bit of taste-testing and found the vanilla flavored EFS more than easy to drink.

It’s a brave new world in caloric intake and First Endurance is coming on strong with the 400-calorie shot (don’t call it a gel), which also has a massive 1,500mg of electrolytes and 1,000mg of amino acids. The fact that it doesn’t have gelling agents and it doesn’t paste up in the mouth means it’s absorbed into the bloodstream quicker. We had a chance to try it, and not only does it deliver the caloric goods, but the vanilla flavor taste truly fantastic. Hitting the flask will soon take on a whole new meaning.
