ENHANCED WITH INSULINRUSH COMPLEX

We know how important insulin spikes are, so our team has developed the InsulinRush complex, an innovative formula with hydrolyzed maltodextrin polymers and inositol.

InsulinRush also contains MicronPure creatine and glutamine.

Xtreme Mass Gainer is enhanced with MicronPure Creatine, a premium-grade creatine monohydrate that’s micronized for better absorption. This advanced ingredient delivers fast-acting creatine to support ATP production, fueling intense muscle contractions and optimizing energy levels during high-intensity workouts. MicronPure Creatine has been shown to improve overall workout performance, promote muscle recovery, and support the development of lean muscle mass, making it an essential component of the InsulinRush Complex.¹

POWERED BY DIGEZYME® MULTI-ENZYME COMPLEX

What good is it to consume an incredible amount of protein if your body only absorbs half of it? Xtreme Mass Gainer now features the patented complex DigeZyme®, a blend of digestive enzymes that helps proper digestion and better absorption of nutrients.

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!!).

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.

Best Mass Gainer

Super soluble, leaves no lumps, super delicious biscuit flavor, and excellent macronutrients (to be adjusted to your diet, of course). The crunchy pieces are also nice.

Perfect

I'm very slim but athletic (ectomorph) and I've received great feedback about this weight gainer for people like me who train regularly. It's a brand that never disappoints. The vanilla flavor is fantastic and not overly sweet.

Recommended 10/10

I don't have much to say, I like that it dissolves quickly, that it doesn't have a strong flavor (it hardly has any flavor at all), and for me, it's delicious and helps a lot to reach those daily calories.

Mass gainer

Sino is a wonderful drink, not too sweet because it doesn't become cloying, it dissolves well, the texture is incredible, and the prices are super good.

Chocolate

The chocolate flavor is unbeatable. This product helps me easily reach my goals. It has plenty of calories, protein, carbs, and creatine—it has everything. Ideal for ectomorphs.
