GFUEL is a fantastic supplement that i find wanting to use when i have a long gaming session ahead as it keeps me focused and alert on what is going on. There are many great flavours that you can find if you try a starter pack or just order packs of 3. GFUEL tastes perfect and has a very consistent feel with no powdery taste left behind, this is good as some products can have this effect. The only problem i find is if your are ordering from outside the US like me then the tax and shipping costs can really add up.
