EnergySource 4:1 is an advanced ALL-IN-ONE training & recovery drink. It’s designed for use both during and after sport to maximize strength and fitness gains.

It contains 4 parts carbohydrate (standard EnergySource) to 1 part whey protein isolate. It’s light, refreshing and exceptionally easy on the stomach. Natural flavours with no colours, preservatives or artificial sweeteners.

A carb/protein combination can reduce muscle damage during exercise and increase muscle synthesis post exercise. Less muscle damage and better recovery results in stronger more resilient muscle, lower risk of injury and more rapid fitness gains from your training.

Available in 1.6kg Jars or in-store as handy 12 x 47kg sachets.

Product Features:

  • Whey protein isolate for muscle growth & repair
  • 2:1 fructose for fast carbohydrate absorption
  • Exceptionally fast hydration (with key electrolytes)
  • Very easy on the stomach (lactose free)
  • Light refreshing taste
  • The Pro’s choice for maximum training benefits
  • With natural flavours. Free from artificial colours, preservatives or sweeteners.

The Journal of Cycle Coaches said this about the benefits of a carb / protein drink:

Quote 1: The latest research indicates that carbohydrate-protein drinks taken during exercise can help reduce muscle damage and reduce muscle mass loss, accelerate recovery and improve performance, especially during bouts of consecutive training.

Quote 2: Compared to a carbohydrate only drink, a carbohydrate- protein drink lowered protein (muscle) breakdown rates by 26% and raised protein synthesis (muscle building) by 33%


The whey protein isolate in 4:1 is the very highest quality. The Food & Agricultural Organisation have an internationally recognised method to compare the quality of various proteins. This is known as the Protein Digestibility Corrected Amino Acid Score (PDCAAS). An ideal protein will have a PDCAAS score of 1.0. The Protein used in 4:1 has a even higher score of 1.14. It’s also high in Leucine, an amino acid which triggers muscle growth and repair.

Dosage & Usage

If you don’t intend to use 4:1 for all of your training,  it is particularly useful if you anticipate a big step-change in mileage, such as a training camp. It’s also fantastic for multi-day endurance racing, as the carbohydrate content is standard 2:1 fructose EnergySource, which provides exceptional carbohydrate delivery. Find out more in the Nutrition Guides section. 

4:1 contains a high level of key electrolytes. It can provide fast hydration as compared to a normal sports drink. The electrolyte levels should be adequate for most race conditions. However, if you use 4:1 or racing over long distances in very hot conditions, you may wish to add one ZERO (Neutral) tab to 500ml of 4:1 for an even higher level of electrolytes and as part of an anti-cramp strategy.
