Iso Energy Lemon Flavour 4.4 5 7 7
Excellent I don't understand why they have changed the pot which is only half full..other than that I have bought this product for years due to me biking and it's the best powder you can use... Gives your performance that extra boost...fab product 06 July 2013
great value Love this flavour as a change to the lemon i normally have... i find both flavours good and the product seems to help at the gym. I drink it as suggested - before gym, during and after - and my times have improved. great value too over buying the individual drinks from super market and love the new packaging.... 17 February 2013
Iso Energy Lemon. Found this to be a pleasant Drink to take for the Gym. One of the better one's which I have found on the Market. 17 January 2013
Iso Energy Lemon. This is great. Easy to mix and not to sweet for me. After trying so many drinks, found one for me. Would suggest it to anyone to try. 29 November 2012
ISO feeling good I use this product as an energy drink before exercising. It always gives me the boost I need to complete my sessions. The only downside is that unless bought on a special offer the price is a little high. 20 September 2013
Good product badly packaged I have used this product for several years and it provides a great way to hydrate, although possibly a bit expensive for what it is. However, the new container is a disaster; it is taller and the top is narrower than the previous tin (as shown on this page) so it is impossible to get a scoopful in one go but very easy to get sore knuckles. Please rethink. 29 January 2013
could do refill pack instead of throwing away could do refill pack instead of throwing away scoop and container every time.this is not ecco freindly!!!!!!!!!!!!!!!!!!!!!! 08 February 2013
