I usually pay close to £22.00 when buying this from Wiggle (RRP is £24.99)!

This stuff seems to get great reviews from most places - 4/5 from MBUK, 9/10 from Cycling Plus and 4.5 out of 5 from Bike Radar.
High 5 Energy Source 4:1 provides you with the energy and extra push you need - when you need it most. Ideally used during exercise, High 5 Energy Source 4:1 can also be used before and after your workout. Containing carbohydrates, protein, BCAAs and Amino Acids, High 5 Energy Source 4:1 works to provide your muscles with energy, prevent muscle breakdown and provide mental focus!
EnergySource 4:1 is an advanced fuel for use during exercise. It contains 4 parts Super Carbohydrate to 1 part Whey Protein. This means that:
EnergySource 4:1 can provide endurance athletes with more energy than carbohydrate alone and that protein protects muscles from being broken down and used as fuel during endurance training and competition. Further research shows that this ratio drives more energy into working muscles, providing athletes with a 24% -29% increase in endurance over carbohydrate only drinks and a 57% increase in endurance over water.
EnergySource 4:1 contains a High Electrolyte Anti Cramping formula , designed to maximise fluid uptake and minimise the onset of cramp.
EnergySource 4:1 delays fatigue: With the right carbs and protein ratio (4 Carbs to 1 Protein) the gastric emptying speed is not slowed and there is a larger insulin response resulting in more carbohydrate (energy) being 'driven' into the working muscles during exercise. Ingested Protein also causes insulin to be released. Another cause of fatigue is only partially understood and seems to be the accumulation of neurotransmitters, namely serotonin, that are associated with negative mood states such as feeling tired or loss of will, in particular parts of the brain during endurance type exercise. By ingesting whey protein and using its BCAAs there is no need for your body to break down muscle and therefore the level of Tryptophan is reduced enabling athletes to exercise or compete longer. Whey protein is considered to be the best type of protein to include in any sports drink.
EnergySource 4:1 prevents muscle protein being used as a fuel during exercise. The protein in EnergySource 4:1 makes more amino acids available for fuel and saves your muscle protein from breaking down. Blood insulin levels are maintained at a high level and Cortisol remains low preventing your muscle protein being broken down and used as fuel.
EnergySource 4:1 also prevents Free Radical damage - Free Radicals are molecules that attack and damage muscle protein resulting in muscle soreness and stiffness.
