SiS GO Isotonic Gel is designed to be taken without water, to provide an energy boost during any intensive activity. They’re available in three flavours; Orange, Tropical and Blackcurrant..

The Orange variety tastes just like orange jelly, which for me is good, but it isn’t an overpowering taste. While many other gels I’ve tried are either gloopy, strongly flavoured or an after taste; the SIS GO seems to win points for being inoffensive. All you want during a run is the energy boost, and this does just that.

The other flavours are also pleasant enough, providing you with a decent selection if you like to stick to the same gel, especially if you’re of a more delicate disposition.
