MUTANT Mass Extreme 2500 | High-Calorie Weight Gainer | Complex Carbs, BCAAs & Glutamine | Hardcore Muscle Mass Shake | 2720g | Cookies & Cream

My husband takes this as an extra meal at the end of his working day, he has an active job so it helps as a filler before his evening meal. It's one of the good ones as it's low in sugar. Cookies and Cream is the best flavour by far! The refill packs are also really convenient.

Had cookies and cream absolutely stunning flavour seeing benefits after 2 weeks of drinking this would highly recommend

Great taste. Good product. No powdery at all. Just like a milkshake. Only thing is it is abit too sweet. But still great product

Huge bag, great value. Really pleasant tasting protein and helps with weight gain. You must exercise as well.

This is a good one and rate really good! To make it go further I ordered a big bag of Maltodextrin and use a scoop or two of that and couple scoops of this.

Great flavour

Very good mass gainer but too expensive

Bought as a meal replacement as I find I skip meals in work often, and my calorie intake is not sufficient for my energy consumption, but also to help me build mass for workouts. The power mixes quite well, and the taste is nice, though it is quite sweet. It’s a shame Sucralose is used in this power, as sucralose is one of the bad sweeteners, which can have potential to cause health problems. Would be improved if this was less sweet, and if a healthier, natural plant sugar/sweetener was used in the recipe. This comes in a resealable bag, which personally I struggle to reseal, so had to transfer this to an old 5kg protein tub.

Carica esplosiva, Te ne accordi durante gli allenamenti dopo 10gg circa di somministrazioni.

Habe mit diesem Zeug mal eben 3 Kg raufgepackt. Teufelszeug was wirkt!

Excelente como siempre es la segunda vez que la compro y encantado.

This whey protein has been a great addition to my routine. It mixes really smoothly with no clumps and has a clean, enjoyable taste that isn’t overly sweet. It’s perfect for post-workout recovery and even works well in smoothies or recipes. The quality feels reliable, and the results have been consistent. Overall, a solid option if you’re looking for a dependable and great-tasting protein.

I won't buy any other mass gainer product. For people like me who are ectomorphs, this is your answer!. I have great genetics, but a metabolism so fast I cannot eat enough in a day to get enough nutrition to make gains....I've been 132 lbs my whole adult life. I started lifting in April '25 and found Mutant Extreme. I take 3 scoops with breakfast and before bedtime, with whole milk. I lift heavy, 4 days a week and I just weighed in at 160 lbs yesterday! So in 6 1/2 months, I put on 28 lbs, mostly all muscle. Very happy with this product. Tastes better than any other protein I've tried. No stomach issues at all like some have reported. May be irritating to anyone sensitive to loctose. 1 serving is 4 scoops so 2 servings gets you the advertised 2400 caloric intake (2600 with whole milk). Mix with heavy cream and it tastes like a whip-cream cookies and cream milkshake! It is loaded with every vitamin and nutrient that a fitness junkie would need. Massively packed with gainer fuel.
