Review: Really works well with combined body effort (working out, good regular eating habits) - This is soo good and tastes so delicious. Love the chocolate flavour I use it with oat milk and a little bit of water and crushed ice. Tastes like a milkshake. Sometimes I add a whole banana and peanut butter to pack in more calories. I can imagine if you drink cows milk you’d pack the weight on rapid. I have put on a stone using this but that was over a space of 6 or 7 months and I was drinking two a day but I’ve cut down to one or forget not good so I’ve had to go back to 1 a day then I’ll be back on 2. You can easily put pounds and stones on with this protein shake. You just have to be consistent really, along with eating. Consume more calories than you need (I’m 9.10st) trying to get to 11 tbh. I was eating pure beef burgers and just lean meat, bread and peanut butter along with any foods high in calorie that pack pounds on, that helped with the weight gain. Be consistent and you’ll get results. Lost count of how many I’ve brought tbh.
Review: Great taste - I’ve used this product on and off over several years. It really is good not full of garbage like you can find in other products of a similar nature. It’s a very well trusted brand vanilla or banana is my favorite as they both taste really good. You can probably use half of the recommended serving each time and still get great results. Just stick to a really good eating plan and you’ll feel the benefits of this.

**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.
