Review: Good - It's helping me put on weight. I added a tablespoon of peanut butter and a banana, tastes really good with the strawberry one. This seems to be the best mass gainer, I've looked around and this is always said to be the best with approved ingredients. It is sweet tasting but if you add some peanut butter it will tone down the sweetness. I'm just doing pushups, ab crutches, planks and dumbbells. I don't go to a gym. With noticeable growth to my arms and chest, just started working on abs to balance it out. I only started to see results after drinking this stuff. Good price on this bigger bag so I think I'll get this one again in the future.
Review: It’s a must buy ! Best & high quality mass gainer! Imo the best out there - I only use this brand of mass gainer… reason being it sits will in my digestive system, it definitely does what it supposed to do. I have used other brands, cheaper brands but they do not pack the punch this do 💪 I have literally been buying this for over 10 years now & will never use other cheaper products. Yes it’s expensive but quality costs money simple! It mix fairly well. The ingredients are of high quality. In my opinion you will not be disappointed & like I said you will definitely be getting the performance you want. I packed on good quality weight… 2st in 3 months but that’s training 5 days a week keeping meals healthy. Hope you find this review helpful.

## Questions & Answers

**Q: What's new with Serious Mass?**
A: Not only does Serious Mass have a fresh new look, but it also has added 3 grams of creatine to support your performance.

**Q: The label looks different compared to the previous one I got, is it still the same OPTIMUM NUTRITION product?**
A: As you evolve, so do we. The part of our mission is to help active individuals better understand OPTIMUM NUTRITION products. Now choosing the right product for you is easier with more visible product benefits, features and flavours on each tub.

**Q: The tub is not full to the brim when opened, why is that?**
A: This is completely normal and is to do with the way the powder is vacuum packed into the tub. The powder settles over time. This does not impact the weight or number of servings listed on the label.

**Q: What is the best way to prepare Serious Mass drink?**
A: To get the optimal consistency and prepare your drink in easy and convenient way, we recommend using a blender. For optimal use, follow serving instructions on pack.

**Q: Are the ingredients tested and safe?**
A: All of the ingredients in our products have been approved and considered safe for consumption by the European Food Safety Authority.
