EnergySource 4:1

Have been using Energy Source 4.1 for training and recovery. Tastes good and mixes easily. Also is convenient as it already has protein mixed. Using this during training seems to have helped with recovery after rides

Great product

Have used this for years. Great taste, easy to mix, kind on the stomach, never bonked when using it. Have used the sachets for events as well. When using the gels as well and followed High 5 recommendations for how many to take along with the drink have never had a problem in a 7 hour sportive ride.

Great Drink

This powder mixes really easy and tastest great...Works wel and easy to drink..

Good product

Great taste, no sore guts, dissolves well and works well wether training or racing.

Great drink

This prduct is very easy to mix, tastes great...I have not used much yet but so far I think this is good and would buy again.

It works!

I'm a sceptical git and tried this as a sachet to begin with. It really, really works. Keeps the bonk at bay and with the protein you're actually providing what your body needs to rebuild as well as the carbs to keep going, genius. I even use this at the gym and the results are noticeable, you can train harder and longer with a much lower level of fatigue. Can't recommend it enough.

High5 4:1

The High5 4:1 Energy Source - 1.6kg Jar is very drinkable taste wise and has had no ill affects on my stomach. It definitely allows me to ride harder for longer. Delivery from Probike was amazing - ordered 10am one day, arrived at the office 10am next day.

liquid energy

The citrus is the best tasting supplement that you can mix with just water. I noticed a huge difference immediately when riding with my friends. I noticed that I don't feel "gassed" anymore during my 2 hour trail ride and I'm leaving my friends in the dust that before I could only just keep up with. I only wish there was more powder in the jar it comes like half empty.... waste of packaging and bad for the environment, I hate marketing.

very handy and reasonably priced

A very handy and reasonably priced all-in-one energy product with carbo, protein and some vital minerals; ideal for longer races, sportives, and other endurance events.

Great Product

This is easy to mix, tasty & good on the body. My go to drink- strongly recommend.
