Great product ! ...very easy to use, taste good, easy to swallow on the move and seem to do just the job. SIS gels are much better now they have increased the contents values, they now more than compete with the competitions equivalent, except far better value.

SIS Gels...: Pro quality, UK made, great to consume, very tasty! TIP: take 1 x gel approx 30mins-1hr before workout/race and then one every 1-2hrs depending on intensity/duration. I run for up to 2 hours and find 1 gel and some organic medjool dates (yum!) before workout means I don't get any noticeable energy drop.... just rehydrate afterwards!
