SIS Isotonic Gels

They work well and no adverse reactions like you can get with some gels.

Great multi pack. Lasted all through marathon training and on the day.

Your isotonic gel of choice is completely personal preference as some tend to cause various side-effects. However, I have now tried s few different brands and I have found that these SIS Go to be just right for long runs (or other endurance events). The pack size is not too bulky and will fit snugly into most belt holsters or pouches, the consistency of the product is probably the best of both worlds - not impalatebly thick such that you end up gagging, nor is it so liquid that you might as well be drinking lucazade.

I occasionally get irritation around my mouth because of the foil packaging - this isn't ideal, and I did consider dropping a star for it. However, I have since reflected and decided that it is likely to be my technique. The past suggests one every 20 minutes which I would say is fine if you are running no more than 12 miles (20km) or so. If you want to go any further I strongly advise you to ration them to perhaps once every 40 minutes otherwise you'll spend the next two days occupying the toilet in rather a lot of discomfort.

As for the taste - these orange ones are the most palatable and the lemon ones are not too bad either. I suspected that they may taste of old army 'screech', but they are actually rather tasty.

I now use SIS regularly for long runs (I actually don't bother for anything less than 10km). One every 40 minutes and sips of water as I go appears to keep me moving

Since picking up the running bug last summer, I've gone from barely running a couple of KM's to doing 10k races. I tried these one Sunday whilst running my first 10k on my own, got to about 6-7K and started to feel it a bit, so had one of these. No idea if it was a placebo, or actually gave me the juice but it certainly gave me a boost to push on and finish the last few KM's with no issue. I make sure I take these now when I'm running anything over 10k. I've only tried the orange ones so far, and they taste fine for me and don't affect my stomach in any way.

Orange SiS is great!

+Pros

Small sachets that can easily fit in a jersey pocket.

Great source of energy if you use them appropriately.

Top can be torn off by using your teeth on the go.

Great value for money

-Cons

Orange isn't my type of flavor

Not a strong taste

Overall the product is great value for money and is a great source of energy. Will be buying again - But maybe a different flavor

These were purchased for my son for football and running … great help when fatigued

Exactly what I need when on long cycle rides.

Cis , you know what your getting !Quality intra sport get

Great value at £1/ea buying in bulk. My favourite flavour and texture of all gels I've tried. I don't bother with caffeine variant as cheaper and more flexible to pack pro-plus

Excellent product for giving you a boost. I usually have one 15 minutes before I need the energy, then I’m good for the rest of the soccer game.

Surprisingly didn't taste too bad and helped me get through my half marathon

Absolute scam, I ordered a box of 30 and received one gel. Just before a half marathon.

Can't fault the gels but awful scam. What

Good for a burst of energy

Have used these on and off for several years, but the recent batch had an unpleasant lumpy texture. Switching to Torq instead.

SIS gels are a bit thicker than some others, but I really like this flavour, the tropical flavour perks me up. There can be a bit fiddly to open, particularly if you've got sweaty hands, but with a bit of practice, they are absolutely fine. They work really well for me

SIS Gels are the best out there currently. So of course these are brill... to Speak more to the Flavour - Tropical flavour is top tier. Purchased the Blackcurrant too, which is hit 'n' miss for some, but I think its good, especially if on a deal.

Nothing to dislike brought for daughter and son inlaw,they said tasted great and instantly felt the difference in recovery time, fantastic for Hydration,great Variety of flavours you can get,Texture fine,Good source of vitamins, size easy to put in bag with gym stuff ,no space needed and no extra weight

I love it this product. Very light while you are running, and give you the carbs need it for any workout or race. You don't need water after taking it. I used it for running long distances like 20k, 30k, and 40k. I definitely recommend this product without hesitation

Having used a couple of different energy gels for running with varied success I thought I would check whats on the market.

There gels certainly have all the science and graphs stating they are the best so thought I would give it a try.

The first thing I noticed on arrival was how big they are. These are well over twice as big as the other gels i have used and quite frankly I dont have the pocket space to carry them on runs. The box says you can use up to 3 per hour but can understand what runner would be able to hold them. These are clearly better suited for cyclists.

I have tried 1 gel so far and it did seem to work but because of the volume in each sachet there is a lot more to consume. This means the taste and consistency are more prevalent than the shot type gels. The flavour (orange) was ok but I certainly wouldn't call it nice. The gel is isotonic so says you dont need water (probably why its so bulky) but ironically you need water to get rid of the taste and residue of the gel.

Overall this is not something I would use again but I can see why cyclists would use them or maybe more hardcore runners who maybe have some mechanism for carrying them better.

Not it's intended purpose but does wonders for a hangover

Yes these are good gels for refuelling on the go.

But in this case my order took nearly two months to arrive!

Not My GYm Supplements's fault I expect probably SIS delivery was at fault.

Considering the price I expect better!

I used to use Gu energy gels but recently switched to these. The flavour is good and the $ per unit is decent. The one thing I wasn't expecting is how big these are. They're easily 2-3X the size of a regular gel. This is because they're very liquid. So they're easy to drink quickly and you also get some added hydration. I really like that for my 10k runs. I'd imagine they might be a bit awkward to carry multiples for a longer run. Recommended!

My go to Energy Gel, so much cheaper buying in bulk.

Helped to get me through a long race.

great taste (for this product category). nice jolt in energy when needed.

Good product. Helps with post workout cramps and keeps endurance levels going during high endurance sports. Tastes slightly bitter, but not disgusting

Great for longer trips where you need that extra boost.

Great taste! Easy to open and great value for money. Helped me get a PB on my half marathon in the hot weather a couple of weekends ago.

I've had to mark the rating down as when the box arrived there was 1 gel pack missing. That being said they're vert easy to use, great taste and good value for money. The texture us stange if you're trying gels for the first time but it's nothing sickly. Perfect size to fit into a pocket for portability when out exercising.

Easy on the stomach, great quality, shame the same couldn't be said for the pre dispatch checks.

Orange SiS is great!

It gave me lots of energy when i was doing my marathon, they are small sachets so easy to fit into your pockets while running, great source of energy. Definite great value for money.

Very good value, gives you energy
