First Endurance EFS Liquid Shot - 32oz. Bottle -

The EFS Liquid Shot - 30oz. Bottle has six 400-calorie servings in it. Most flasks we have take five to six ounces of fluid. The bottle grande takes 32 ounces of fluid, but is filled with 30-ounces. That's about the same caloric punch as 16 bars. We're comparing the calories; solid to liquid, because the Liquid Shot is different than the gels it competes with. It's apples to apples.

For one, it's not a gel. No gelling agents are present. Without these agents, the liquid is less viscous, goes down more easily, requires less drinking from your water bottle afterward, and doesn't need diluting to get every last drop out of the flask.

A flask's worth of the LS is 400 calories. Of the 400, there are 100g of carbohydrate in a mix of glucose, maltodextrin, and sucrose. The reason for the mix is to have fast-acting, slow-acting, and easy-absorbing carbs. The bottle also has 1000mg of amino acids, broken down into glutamine and branch-chain amino acids isoleucine, leucine, and valine. There is also a pretty heavy-duty electrolyte blend of 400mg sodium, 290mg potassium, 150mg calcium, 120mg magnesium, and 600mg chloride. As all cyclists should know, we sweat out salt and have a great need for electrolytes when exercising hard, and the loss of salt can lead to cramping. First Endurance argues that you need more than just salt to prevent cramping; that's why the rest of the electrolytes are present. The Liquid Shot will keep your electrolytes balanced, help with absorption, reduce lactic acid build-up and keep the body going.

The container can sit sealed and unrefrigerated for a year, but once opened, should be stowed in your refrigerator. If a flask is unfinished after a ride, pop it in the fridge and keep it there until the next ride. First Endurance EFS Liquid Shot is available in Vanilla and Wildberry.

First Endurance EFS Liquid Shot - 32oz. Bottle Reviews:

Positive Reviews:

This offers the most electrolytes of any other product I've come across. I've been using the liquid shot since the end of last year and love it, it's definitely helped my endurance and hydration. The Kona Mocha flavor is my favorite, I don't even drink coffee and I can't get enough of it. I use the product "half strength"; it's very thick at full strength and can be tough to get out of the 4oz flask when cold. I use half of the liquid shot and half water to cut down calories and so it's a little easier to use on the go. I LOOOOVE this stuff!

I've already rated this procuct (which is 100% great) and my review would have been expanded upon, but Backcountry pesters customers with emails about reviewing products - not good.

Neutral Reviews:

Not a big gel/liquid type fan, but thought I would try it out. Certainly does give you a boost but just doesn't sit right for my belly.
