Mutant SURGE Triple Chocolate

I'm impressed! As a fitness enthusiast, I've tried various protein supplements, but this one truly stands out. The taste is fantastic; it's like having a delicious dessert treat every time I mix it with water or milk. The smooth texture is a pleasure to drink, with no gritty residue. I appreciate that it contains pure whey protein isolate, ensuring I get the highest quality protein without unnecessary fillers.

Another aspect that caught my attention is the quick absorption rate, which has noticeably improved my post-workout recovery. Within a short period, I've noticed increased muscle definition and reduced muscle soreness. Tastes good. No complaints.

My protein supplement

I love this protein. I love the flavor as well. Easy to mix and use. I use this as my supplement for my protein. Taste is good and it mixes well with my shaker

Great taste and value for money

Great price and this product tastes great.

Dessert -Squirty cream on top 🤤

I got the banana flavour.. I make it with half milk and half water it tastes great.. mixes well with no lumps in a shaker. No stomach issues as it's isolate. That tasty I bought another tub a few days later.. good price at £27.

Perfect quality

This is my 3rd order from this company and I am absolutely satisfied

Best Whey Protein on the market but overpriced

This product contains solely Whey protein isolate and Whey protein hydrolysate. Whey Isolate removes most of the fat, cholesterol and lactose in the whey so it is easier to digest and hydrolysate is a pre-digested form of isolate which also allows for easier digestion and absorption. The flavour is great having tried peanut butter, strawberry and chocolate from this company. I'm unsure if they added BCAA's and glutamine to the product or if they are stating the glutamine and BCAA content in the protein at present. Whey protein naturally contains EAA's, which are all the essential amino acids (including BCAA's) and glutamine. Overall good product and I recommend buying if cost is not an issue to you.

My GYm Supplementsg stuff

Most protien powders make me sick for some reason. This one doesnt and its been amazing!

My protein supplement

I love this protein. I love the flavor as well. Easy to mix and use. I use this as my supplement for my protein. Taste is good and it mixes well with my shaker

Horrible taste

Can't taste the vanilla icecream, the taste is horrible

The best protein powder out there.

I've been taking different protein powders for the past 20 years and this is by far the best for ingredients and for flavour. I bought the mint choc chip ice cream and the taste is unbelievable and with 78g of protein per hundred grams your onto a muscle building winner. Will 100% buy again.

Price has just gone up by 10 quid 🙄

Not good as a paste but shake is fine

Perfect item but does not make a good whey paste !

Decent product

Good product for a good price. The taste is decent, but compared to the delicious pro 100 is nothing special.

High quality whey, superb after sale care

I ordered this product on a recommendation from my training partner.

The flavour is incredible and strong 10/10, lots of proteins leave a nasty after taste and/or have a weak flavour. My buddy has the mint choc chip and it contains chocolate chips, need I say more?

Next would be mixability, again 10/10, the powder is fine and smooth, and easily blends with your water/milk. I have found no bitty residue left in my shaker like other name brand protein.

After sales care by Fit Food, 10/10, I had a small issue with my order. I contacted Fit Food and their reply was friendly and fast, they also went above and beyond to sort the issue.

To sum up, you should definitely buy Mutant Iso Surge from Fit Food, I know I'll be back for more flavours.

Great Taste (Banana Flavour)

The banana flavour tastes very similar to the banana medicine we had as kids. Don't be discouraged about people complaining about it being "Half full" because the side indicates that it's exactly 22 servings when filling the supplied cup to the top. Great value for its price and will be trying different flavours in the near future.

Not the best

I loved the vanilla milkshake flavour of this protein so much, but the strawberry has an off taste to me and I just do not enjoy.

Had to reorder due to first one not arriving, after receiving refund this one arrived on time.

Protien is good as I have purchased previously.

Best protein on the market

I've tried multiple different proteins and always return to Iso Surge. Best for taste and quality and at a reasonable price.

Lovely flavour

Lovely flavour, wasn't ever quite sure if I liked the choc chips though. But decent protein for the money
