Mutant Mass Weight Gainer Protein Powder – Build Muscle Size and Strength with 1100 Calories – 56 g Protein – 26.1 g EAAs – 12.2 g of BCAAs – 15 lbs with 24 Servings – Cookies & Cream

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.

This is the best mass gainer I’ve ever seen and tasted, you can mix it with anything, just whatever you want it ll still taste great. I’ve been using it before so I wanted to try again and in only two weeks I gained weight so imma order it right now cuz I only have one scoop left 💀☠️

Very big bag of greatness. Easy on my tummy awesome for weight gain.

I've been taking this for the past week now and I have been following a very regimented diet and eating around 205g of protein a day and 3700 calories to gain weight and muscle. This drink is a great addition to my diet and helps me with reaching my calorie intake, but that's about it. There is about 30g of protein in 4 scoops of this and it is thick like a milk shake. It's easy to drink but I think just because I'm drinking this everyday its getting bland. The taste is super sweet, it doesn't say how much sugar is in it so I don't like that but based on the ingredients I would say that it's a pretty good mass gainer. I'll more than likely continue to use this brand, but I will be switching to a different flavor. The cookies and cream is a little too sweet for me on a daily. I don't feel bloated at all when drinking it and I have no issues with gas or anything. So, again, super high quality mass gainer, just very sweet in my opinion. I wish it was like half as sweet as it is. I would recommend. Just be aware of the sweetness.

The powder mixes well and the cookies and cream flavor tastes delicious. I use vanilla almond milk to mix it with. I have only been using this for about two weeks so I can’t tell if it helps to grow muscles. I’m a little concerned about the cholesterol content in this product so I might just mix one scoop with a cholesterol free powder from another brand.

Stupid me, I read the 2500+ calorie claim. Bought the mutant mass cookies and cream thinking I was getting such great value. 1 serving is 4 scoops, which is a very full shaker bottle. 1 serving is only 1047 calories. To get the advertised 2500 calories they tell you to mix 2 servings with 1% milk. I was getting more from on nutrition. Do t waste your money - tastes like meh, and it’s very gritty and doesn’t dissolve even overnight in the fridge. Garbage.

These are great products!!!

Buono ma ha un gusto davvero artificiale

I’ve been using this gainer for a few weeks and the results are really noticeable. It mixes easily, tastes freaking great (cookies and cream is delicious without chemical taste and even with water its wow), and packs a high-calorie punch without feeling overly thick. My workouts feel more productive, and I’m starting to see real gains in muscle size and strength. Perfect for anyone looking to add serious clean calories and bulk up efficiently.
