Give it your all.

When you need maximum calories, but want minimal bulk, EFS Liquid Shot will have your belly full and your legs flying. In fact, EFS Liquid Shot contains so many calories, that it’s not fair to compare it to other liquid nourishment, be it gels or drinks. The 30-ounce bottle contains six, 400 calorie servings, which far outdoes any other gels, with most weighing in at 100 calories each.

You get 100-milligrams of amino acids in a combination of glutamine and isoleucine, leucine, and valine. To keep your system functioning, the Liquid Shot also features 400-milligrams sodium, 290 milligrams potassium, 150 milligrams calcium, 120 milligrams magnesium, and 600 milligrams chloride, because you need more than just salt to keep all your pistons firing.

Finally, you won’t be squeezing a sticky gel into your mouth. The EPS has a higher viscosity due to the lack of gelling agents. It goes down easier and needs less water to dilute it. The container can sit sealed and unrefrigerated for a year, but once opened, it 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.

Easy on the stomach, easy to get down.

  • Familiarity:I've put it through the wringer

I have been using EFS Liquid shot for several years now and continue to have great experiences with it. It doesn't seem to have the impact on the stomach that I've had with other gels and it's really easy to consume out of the Liquid Shot bottle. One of the biggest high points to me is that you don't have to deal with wrappers (getting them open and inadvertently littering). True one-handed operation!

is this worth the carry on long backpacking...

Best Answer

I suppose it would depend on how long you plan on being out. If it was a five or six day adventure, sure, perhaps. However, you have to account for the size of the bottle that you would have to continue to lug around until you got back to town before you could ditch it (remember LNT principles!). That would be an awfully big item to tote around for days on end after you finished it, not to mention, liquid is heavy as it is. I think there are better alternative around that could provide you with similar, if not identical, benefits at a fraction of the weight.

Hope this helps.

I use this product a lot on day trips and high intensity activities - gives a good kick when headed for a bonk. On longer trips and low intensity activities I prefer to get my calories in more satisfying ways - nuts, energy bars (like probar or cliff). You get more calorie/weight in those. If you do decide to use this product I recommend first buying a six pack of the five oz. flasks. Then reload those with the bigger volume bottle. You can reuse the small flasks for years (at least I have) and they pack easier.

My bottom line opinion is this is really not worth bringing on multi day trips since you can get your calories in more dense and satisfying ways. This is super sugary sweet - not terrible, but certainly not something I salivate over in anticipation! The ideal use for EFS is when you are involved in fairly intense activities (racing, backcountry skiing, climbing), and you need to keep the calories coming in a quick and easily digestible manner. For that purpose EFS is great.


Sent expired product.

  • Familiarity:I've put it through the wringer

Star rating is for Competitive Cyclist shipping expired project. There really is no excuse for this. Expiration date clearly printed on bottom of bottle.

Otherwise, EFS Liquid Shot is great stuff.

Really? A simple call to customer service could fix this.


Its a much lighter gel. More liquid

  • Familiarity:I've put it through the wringer

I like this one as its more of a liquid than a gel type product. I use it with my gel infusion kit on my camel bak (the old zero goo). Nice, easy on my stomach and alot of gels upset my stomach. Packed with lots of energy. I've only had the vanilla. Nice flavor.


So so for me anywat

  • Familiarity:I've used it several times

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.


Backcountry, simmer down with emails

  • Familiarity:I've put it through the wringer

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.


As awesome as all 1st Endurance products

  • Familiarity:I've put it through the wringer

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!
