IEGreat products and great support Great products and great support - I was in contact with their support and they were brilliant and responded immediately. I got next day delivery. I would recommend and I will be getting more stuff especially the chew gels as soon as these ones are used up!

GBFantastic products especially the Beta… Fantastic products especially the Beta line . Trying to take onboard more carbohydrates while cycling and feel it's fuelling me really well, with no drop off in performance. Have noticed my recovery seems to be better also when ingesting more carbs. Great products all through the range.

GBProduct good packaging ridiculous. Item arrived on time and happy with the product. The worst thing is the packaging a massive box for two small items was ridiculous. Had two separate orders and both were in a similar size box and both items were small enough to fit in a box half the size.
