Best Taste

De smaak van dit product is verre weg beter dan de meeste massgainers die ik heb gehad. Lost goed op geen klonten. Goeie fijne textuur niet te dik en goed weg te drinken.

STRUGGLING TO GAIN WEIGHT?

Prozis Mass Gainer actually tastes great and has creatine built right in, so I''m covering my calories and recovery needs as a hybrid athlete in 3 scoops. Consistent, effective, and doesn''t taste like chalk - highly recommend!

Love This Stuff!!

I been using Xtreme Mass Gainer for the past 3-4 months on my path from 132lbs (Dec ''25) to 175-180lbs (160lbs today). This is fundamental in my nutrition efforts as I have a high metabolism on top of low calorie intake on some days. I wanted something that was effective but also didnt have much sugar. After research this was a no brainer. Chocolate is my favorite but I find myself using the Vanilla more because it is a great base for most my shake recipes (especially with berries!!).

I love this product.

I'm someone who needs to consume a lot of calories throughout the day, and this product helps me achieve that. Obviously, it doesn't replace the necessary protein I need to consume daily, but it does help me reach my calorie needs.

Perfect

I loved it in every aspect; it doesn't get lumpy, it's flavorful and not cloying, it's perfect for those who need carbohydrates.

Positively impressed

Excellent gainer in every way. I've used gainers from other brands, but I don't think there are any like this one. Excellent, delicate flavor with no chemical aftertaste. Exceptional solubility, no lumps. Excellent digestibility and not heavy.
