The team at Protein Package are great. They’re personal and care about what they’re doing and how they do it. They’re site is easy to use and their products are quality (and impossible to find elsewhere). Not to mention they’re prices are unbeatable. Great company, cool people and quality products. 10/10

Amazing !!!

These are sooo good! Honestly the texture and the flavor could not be more on point. If someone told me this could to be the only thing I could ever eat again I probably would not even be mad.

Grenade Carb Killa Bar 1x60g / Fudge Brownie
28 January 2022

This is my first try of the Grenade range. I am trying them, as I am struggling to get my usual 60g Atkins mint bars, so thought I needed to look for alternatives. I did enjoy this fudge brownie bar and will be buying it again. I have also enjoyed the caramel chaos, Grenade Jaffa Quake, white chocolate cookie, so will be buying these again too. I still have a few other flavours to try.

I’m just getting into fitness, tried a couple other bars they either did not taste decent or were spiking my sugar. These don’t, taste is good , paired with some fruit is a deadly snack that’s low sugar, low in carbs and taste good.

I bought this last week i was expecting it to actually taste like a vanilla birthday cake, or at least somewhat similar - it doesnt. While ive heard its among the sweeter tasting Grenade bars, its not super sweet so if you are new to protein bars be aware of this. The texture is alot more chewy and dense than i was expecting and it does have that synthetic protein taste. Really dissapointed but ive heard people enjoy it, maybe buy 1 first before buying the 3 for £5 like i did as i dont find myself reaching for them.

Possibly My Favourite Grenade Bar!

I have a sweet tooth and I like sweets over chocolate in most circumstances - so was excited to try this and I wasn’t disappointed! Good sweet lemon flavour, delicious 😋

Surprisingly delicious
11 July 2019

As a dyed-in-the-wool dark chocolate person, I didn’t expect to like this as much as I did. I bought a couple on the off chance that I might just like them, but these are now regulars for lunches. They have a lighter texture than, say, the dark choc raspberry bar, which works well with the cakey vanilla taste and crunchy coloured sprinkles. Macros look pretty good too.

Yummy....but different
16 August 2018

It's delicious don't get me wrong, it's just a different texture than the other flavours. Aside from the sprinkles on top (that go EVERYWHERE fyi) there is no crunch or array of flavours on the inside like for example the caramel chaos. It's simply vanilla spongeiness with vanilla "icing" and sprinkles. As noted above super yummo though, just a bit unexciting

best ever bars
29 August 2021

Best bars ever. Bought them as fairly low carbs. I am diabetic and they do not raise my blood sugars. Miss chocolate, and these are certainly a good replacement. Very tasty.
