It has a rich, smooth chocolate flavor that makes it enjoyable to drink, and it blends easily without clumps. Packed with a good balance of protein, carbs, and essential nutrients, it helps support muscle growth and recovery. Overall, it’s a great choice for those looking to gain weight or build muscle.

Great Taste & Texture. Effective.
Long-time Serious Mass user. I use it as a meal replacement for days when my schedule is jam packed and getting lunch is not an option. Tastes great. Quells my hunger and keeps my muscles fed.

Good taste
[This review was collected as part of a promotion.] The taste was better than I was expecting! I made a strawberry banana chocolate smoothie and it was good! Lots of protein for not too many calories and didn’t leave the smoothie too chunky.

BEST PROTEIN!!!
[This review was collected as part of a promotion.] The taste of this is amazing! Very much chocolate and a good texture. It blended nicely in my shaker bottle and I looked forward to making and drinking a shake. It is high calorie and full of protein and helped me achieve my goals for in and out of the gym!

Good but flavour isn't the same
Two scoops can definetly be alot. The flavour is also thicker in a more negative way compared to the regular chocokate protein powder. It's still good, it's just not the phenomonal chocolate flavour that I've always enjoyed from them.
1 reply from Optimum Nutrition team - 1 year ago
Thanks for the review! Some users of Serious Mass opt to split the 2 scoops over the course of a day so that the entire serving does not have to be consumed in a single sitting.

Best for Bulks
[This review was collected as part of a promotion.] This protein power is delicious! It is such a good way to help get in more calories for trying to bulk. The taste is also delicious on its own or even good with other fruits mixed in with it!

Good
[This review was collected as part of a promotion.] I have already been using this brand and flavor hence why I already have one in the picture. I don’t feel bloated after taking these and it taste good if your a fan of chocolate. I would also use it and make over night oats/yogurt.
