Turbo power - feel the difference.
on 9 February 2015
I have used many carbo gel, but nothing comes close to Viper Boost. I use to buy these easily from Tesco or Boots, but now they do not stock. So i tried the alternative - SIS gel. I felt no difference using the SIS gel. I have tried the Energygel, this is also good, but when you use the Viper boost, you can actally tell the difference. The endurance levels are far more higher and I can last longer giving 100% in my training without feeling the fatigue.
