A shaker and seven tubs for myself, and five spares.

I and many other Gamers have often seen this brand sponsoring eSport events and big-name YouTubers, and while our beloved YouTube Game Gods have often shown their passion for this brand we have yet to actually see reactions to what this product tastes like, or if it even works.

I have come into possession of several tubs of G-Fuel and will be sampling a different flavour every day for a week, making notes of how it tastes and if it actually improves my performance (both as a Gamer and as an Artist), or if it produces any unexpected side-effects. It is recommended you only have one serving a day, though you can have up to two after using it for a while, so I will only be sampling one flavour a day for this reason. Each serving equates to one scoop of G-Fuel added to 12oz of water, and shaken until dissolved.
As I have a weak to non-existent sense of smell I was unable to detect how the drinks smelt, however my sense of taste is very sensitive (as odd as that may sound). For future reference, I will not be describing the smell of the drinks as I cannot smell them.

So without further delay, I will begin with the reviews.

DAY 1 - Cotton Candy

There are a few flavours I was very interested in trying out, and at the top of the list was Cotton Candy, so as expected it was the first one on my list for the weekly taster. The powder was white to my surprise. When added to water, it turned the water pink. I took my first sip and let the drink linger in my mouth to get the complete taste, and it certainly did taste like Cotton Candy...for about 15 seconds. After the punch of flavour it became very stale with a lingering chemical aftertaste, and left my mouth feeling very dry. Granted I left the drink in my mouth longer than a typical eSports consumer, who would likely just swig it while they were in the heat of gaming. I then decided to drink it like the gamers I often saw promoting the drink, which was in quick bursts without letting it linger in the mouth, and while the aftertaste still kicked in it did not linger around as long as when I drank slower. Once the beverage was completely gone I then had a very dry mouth, drank 2 litres of water, and was still sat an hour later with a fairly dry mouth.

Will I return to this flavour? Probably, just to use the tub up and not waste it. I won't be buying this flavour again though.

DAY 2 - Fazeberry

This flavour of GFuel has a very distinct taste of Berry! Even better is that the taste of fruit remains a bit after consumption and did not have the chemical aftertaste. However, it still made my mouth a bit dry.
The drink was a white powder that turned the water a cherry red when mixed. The Berry flavour was a distinct combination of pomegranate, strawberry and what I believe is blackberry. Pomegranate was the dominant flavour. This was made as a Special Edition, yet it is labelled on the G-Fuel Website as "Limited Edition".

Will I use this flavour again? Absolutely. I would buy it again in the future, if it wasn't a "Limited" thing that is...

This flavour can be found in the UK here.
Or directly from the USA here.


DAY 3 - Fruit Punch

This flavour, as is appearing to be the norm of the drinks, started out as a white powder until mixed with water. It turned the water a reddish colour much like the Fazeberry did.
The drink had a very similar flavour to the Fazeberry one, but with a more sour taste, but when chugged (not sipped) it indeed did taste like a fruit punch! Raspberry and Blackberry were the most dominant fruits in the taste. There was no chemical aftertaste, but again my mouth was a bit dry, but not as dry as before. This flavour will remain one that I will come back to for future use.
I was hit by a bit of a cold and my energy levels were terrible, but the GFuel did pick them up a bit. However, until this cold is gone and the 7 days are complete I cannot say for sure if it will have helped me with my concentration or performance.

DAY 4 - Pink lemonade

Okay, so now the pattern for G-Fuel suddenly shifts. Pink lemonade is a pink powder, not a white one, that when added to water, changes the water to the same colour as the powder. This was a surprise.
To those who have never tasted Pink Lemonade before as a drink on its own; it is made using Grapefruit and is just as sour as regular Lemonade, but has a very distinct difference in flavour, as Grapefruit has a different effect on the tongue compared to Lemons that allows us to better taste the fruits flavour.
Does the G-Fuel match up? It does in a way; it tastes just like flat Pink Lemonade, it probably even smells like it too since I could taste the vapours before the liquid even entered my mouth. As with the past 3 flavours, my mouth was left a little dry after drinking it.

Will I be coming back to Pink Lemonade? Absolutely. I imagine it tastes even better with ice on a hot day!

DAY 5 - Peach Mango

Once again I opened the tub of G-Fuel expecting it to be white, and found this flavour to have a slight orange-tint to it. When mixed with the water it turned it a pale orange, almost mango in colour.
On first sip I got the distinct taste of peach but no real flavour of mango, it did however have the lingering flavour of mango once the peach taste faded. Each sip was consistent in flavour. Unlike the last few flavours this one did not leave me with a dry mouth, and is actually very refreshing. I imagine it tastes even better with ice.

Will I return to this flavour? Most certainly! While it isn't my top choice in terms of taste, it is my favourite in how refreshing it is. I will most deffinitely be coming back to Peach Mango for the hot summer days!

DAY 6 - Twisted Kandy

Another flavour I was very interested in trying out (can you see the pattern yet?) but decided to try towards the end of the G-Fuel tasting week. Upon opening the tub I was greeted by the familiar white powder once again. When added to the shaker of water it turned the water a light green.
The taste of Twisted Kandy is unusual; it is slightly fruity with a hint of the sugary-syrup type of flavour atypical to a stick of rock-candy,you know, like what us Brits can find at places like Skegness or Blackpool! It had a very grainy consistency to it, which at first I thought was down to me not shaking it enough, but even adding more water and shaking it for a solid 5 minutes didn't make this go away. After drinking Twisted Kandy my mouth was only slightly dry.

Would I return to Twisted Kandy? Yes, to finish the tub. Would I buy it again? Probably, just for something different. Is it better than Cotton Candy? Absolutely.

DAY 7 - Ragin' Gummy Fish

The G-fuel powder once again was not white! Upon opening the tub I was surprised to find it a pinkish red, slightly darker than the Pink Lemonade flavour. When mixed in with water it turned it a light red.
This was yet another flavour I was curious to try out, not just because it is a type of candy, but because I genuinely was curious to know what even is a "Ragin' Gummy Fish" flavour supposed to be? I did some thinking the day before trying the G-Fuel, and believed that, maybe, it was meant to be like a strawberry jelly with that white spongy jelly underneath it. You'll know what I mean if you've ever eaten the love hearts found in Haribo Starmix. Anyway, when I took my first sip it really did taste just like those Haribo hearts! It was fruity, but more the type of fruitiness you get from a jelly rather than a juice (like the Fazeberry flavour). This G-fuel had no chemical aftertaste and was oddly very pleasant considering it's strange concept, it did not leave my mouth feeling very dry at all.

Would I recommend this flavour? Yes, for the sweet enthusiast like myself. I would certainly buy this flavour again in the future.

NOTE: This section covers the results of tastings and if I saw any improvement in a week. The full results of if G-Fuel works for energy, concentration and performance, will be revealed after the monthly testing period is over (July 31st). This will be found in a video and miniature article below this section.

I have now sampled all 7 flavours of my selection of G-Fuel and to make things easier, for folks who like to make their choices based on fancy visuals, I have compiled each sampled flavour into a "Tier Chart". The template I used is a meme because hey, memes are fun.

I have noticed a pattern in my tastings, and it is fairly clear on the chart too where G-Fuel works best in flavour and where it does not. Generally, all "sweet and candy" themed G-Fuel is lower in the tier even though I love my sweet things, while the more natural fruits sit higher on the list. This could just be down to the fact that it is harder to simulate the flavour, of an already existing artificial one, in the formula. G-Fuel say all flavours are made with natural ingredients, so this explains why the fruit-themed drinks tasted the best.
It is worth noting that while G-Fuel is sugar-free a large selection of the flavours contain caffeine (1 serving has about the amount you'd get in a large cup of coffee). They do offer caffeine-free flavours, but not many, and this could explain why my mouth often found itself dry after consumption; caffeine naturally dehydrates you. You can get G-Fuel that is caffeine-free, or go for their Hydration Formula, but the selection of exotic flavours for those two options is quite low.
In terms of healthiness and benefits to using G-Fuel, I have done some research whilst going through this taster week; the formula contains multiple antioxidants that are extracts from a large selection of fruits, vegetables and other plants. While this may be great for those looking to axe artificial products, G-Fuel is not 100% natural either; many colours and flavourings are artificial, especially those found in the very exotic flavours like Twisted Kandy and Ragin' Gummy Fish.

Okay, now that the flavours and explaining why my mouth was dry so much is over and done with, you probably want to know if G-Fuel even works. Well I had a cold for 2 days and drinking G-Fuel did seem to help me fight it off better, as a family member who didn't drink the G-Fuel was still suffering from the same cold I had 3 days later. However, this could be down to anything, from my age to my level of stress, or even the temperature of my room. I cannot say G-Fuel certainly did benefit me during my period of illness, but I assume it played a role in keeping that illness from stopping my daily activities.
One week, and especially a week of illness, is not long enough in my own opinion into seeing if G-Fuel really does improve my performance as a gamer, my focus as a writer, or my energy levels as someone who juggles multiple tasks at once (and frequently becomes exhausted). To make a final conclusion into if G-Fuel does work, I will have to run an experiment for at least a month.
