Pound for pound, Mutant Mass is the best weight gainer on the market. Highly recommended for anyone looking to pile on slabs of muscle mass in a short period of time.

I had just finished my first marathon and after four months of endless cardio, vaseline and one very sore ballbag, I was left looking a little on the slim side.

I wanted to gain muscle mass – and fast.

It’s not that I didn’t mind looking a little slimmer, I just wanted to build some serious, intimidating bulk.

Let’s face it, Mo Farrah might be able to run a mile in 3.30 minutes, but tasked with ordering a round of WKDs at Wafou Norwich on a busy Wednesday night?

No chance!

While my gym programme was shaping up nicely (I was doing Stronglifts 5×5 – a no-nonsense full-body routine which focuses on squat, deadlift, bench, rows and overhead press), it became apparent that I needed to turbocharge my diet for the sizeable results I was after.

It was at this point that a friend recommended I try Mutant Mass.

In his professional opinion, I would “hit 17 stone on this bad boy – instantly”.

I was sold.

Product Overview

mutant mass reviewTrue to its name, Mutant Mass is an absolute behemoth amongst weight gaining supplements.

It packs a multitude of impressive ingredients, but perhaps the most eye-popping USP is the sheer amount of calories it contains – 1,060 kcal per serving, to be precise.

Let’s put that in perspective…

That’s about the same number of calories as a typical Sunday roast – in one shake!

Completely obscene!

When it comes to the rest of its goodies, per serving we’re looking at a nice ratio of carbs to protein (176g clean carbs, 52g protein) as well as a decent blend of amino acids – great for aiding recovery.

The recommended number of scoops is four per serving.

By the very fact that I had to shovel this colossal amount into two separate shakers, I knew this experience was going to go one of two ways:

One way was good, the other… would be fucking horrible.

Taste & Texture

I used a blender to mix Mutant Mass with milk, and I was pleased to find that, on drinking it, lumps were minimal.

Good start.

However, due to the absolute tidal wave of calories, it was still a struggle to get down.

I tried shaking it once  – without a blender – but never again.

Getting the thing into a drinkable state required a titanic effort and considerable wrist strength – think power wank.

Taste-wise, I had no complaints.

I opted for the Cookies and Cream flavour and, quite frankly, it tasted delicious.

Mind you, I was a student at the time, so bear in mind my palette had been corrupted by a strict diet of burnt toast, kebabs and industrial strength cider.


The 67kg bag of Mutant Mass lasted me just over three weeks, and in that time I achieved some pretty impressive size and strength gains.

Alongside a high calorie diet, 4×1 hour workouts per week, and minimal cardio, I put on about half a stone in weight.

And the good thing was that most of this bulk was lean muscle.

Obviously, with a weight gainer of this magnitude, its never going to be 100% muscle.

Inevitably, I grew a little bit of a gut – but nothing that a small amount of cardio wouldn’t fix.

Perhaps more impressive, however, were the strength gains.

Let’s take every gym rat’s favourite exercise – the bench press.

Prior to taking Mutant Mass, I had plateaued at around 85kg for 5×5.

However, during my stint with this mass gainer, I managed to increase the weight I was benching on 5×5 from 85kg to 95kg.

Not bad, eh?

What’s more, I managed to increase the weight I was pushing on all my other compound exercises quite considerably.

Side Effects

No Mutant Mass review would be complete without mention of one inconvenient side effect…

WARNING: As well as building mutant size, this product gives you some serious methane issues.

We’re talking toxic guff gas here.

I cleared offices, supermarket aisles, tube carriages – and on one occasion around 25 people from the dancefloor of my student union.

And if that wasn’t enough, every shit was like giving birth.

This stuff made me feel continually bloated – it was like digesting cement.

DO NOT drink Mutant Mass before a night out – turtle bellies all round otherwise.

Value For Money

Usually retailing at around £68 for a 6.8kg bag, value-for-money is pretty damn good if you ask me.

Obviously it’s not cheap, but for what you get, it is, in my opinion, one of the better value weight gainers on the market – and certainly a safer bet than some of the bargain basement brands out there.

It’s certainly the best I’ve ever reviewed.
