SIS Go Energy drink is a powder that you mix with water. It contains carbohydrates to provide energy, and that's it. No frills, no extras. It's easy to digest and tastes good, and will help keep you going on a long bike ride. It's also fairly priced.
Previously on road.cc we reviewed the version of this product that's available in small sachets. Now we're reviewing the new 500g tub of powder, which is also available in a new flavour – elderberry – but otherwise it's the same stuff.
The main ingredients of Go Energy drink are maltodextrin (produced from maize) and fructose. There's also citric acid, some natural flavouring, and sweetener (aspartame). This gives 94g of carb per 100g of powder. There's no protein, and virtually no fat, fibre, sodium or other minerals.
The label on the tub recommends a serving of 50g, so 47g of carb, with 500ml of water, while the SIS website indicates you can mix the powder at "high energy concentrations, to give you lots of energy per mouthful", presumably something like 70g or 100g per 500ml of water. Conversely, many bike riders prefer a slightly more diluted mix. As with all energy products, it's best to try various mixes when you're training, find out what works best for you, then stick to it when you're doing a big race or sportive, or just a long ride.
In practice, I have found this energy drink works very well. I usually put the recommended serving ratio (about 70 to 80g) in a pair of 750ml bottles and it's enough to see me through a two to four-hour bike ride. Longer than that – eg a 100-mile sportive – and most cyclists (myself included) will need more carb, usually in the form of energy gels and bars or 'normal' food.
On price, the 500g tub of Go Energy drink is currently going for a penny under a tenner on the SIS website. Certainly cheaper than the individual sachets mentioned above. You can save even more by buying a 1.6kg tub for £24. This is a fair price against similar carb-based drink powders from other brands (eg, £29 for 2.2kg of High5's Energy Source) although both products are further discounted on the usual online stores.
Easy-to-drink no-nonsense carbohydrate drink; ideal source of energy for long bike rides

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
This is an energy drink. It contains almost all carbohydrate. There's no protein, and no minerals/electrolytes. The SIS website says:
"47g of carbohydrate per serving.
Provides fuel before or during training and racing.
Reduces the risk of early fatigue during exercise."
Tell us some more about the technical aspects of the product?
The SIS website goes on to say: "SiS GO Energy is versatile enough to mix at high energy concentrations, to give you lots of energy per mouthful. Prepare: Use to take on board low bulk carbohydrate for carb-loading and boosting the carbohydrate in pre-exercise meals. Perform: Use during exercise to energise your performance or to re-fuel hungry muscles. SiS GO Energy can be used immediately after exercise to re-fuel."
Although it won't do any harm to refuel with this product after a long ride, most sports scientists recommend taking on protein to help muscle repair and recovery. Go Energy has no protein.

Anything further to say about the product in conclusion?
SIS Go Energy drink is just that: an energy drink. It does what it says on the tin. There are drink products available from other brands (and SIS) with additional ingredients to provide protein, minerals or other bells and whistles, but for straightforward energy, this stuff is excellent and would score 9, but gets a point knocked off for the price which, although fair, isn't a bargain, giving an overall score of 8.
