5/5
Love this protein powder. Vanilla flavour best for mixing in a smoothie after a workout.
5/5
Awesome taste, really easy to drink and doesn’t leave bloating like some other products tend to leave. Powder is super easy to mix and doesn’t leave any gritty feeling in your mouth. The strawberry flavour taste like any branded milk but can get sick let after a while.
4/5
A filling shake.
4/5
Tried a few diff mass gainers, this one is definitely on the tasty side. Easy to mix with fruit etc. Will definately buy again. I tend to bounce between this and MusclePharm Combat XL. Always the vanillas as I find them easier to mix with other flavourings...mio...
5/5
Amazing flavours have tried 3/4, easy to drink and the most mixable powder I’ve tried. Very gentle on the stomach no issues with digestion. Great powder for beginners and pro. Obviously results can vary person to person and for goals. I used to outlet gain weight and worked for me really well.

Serious mass chocolate flavour is very delicious when mixed with minimal water to make it just thick. It gives me more energy and significant improvement in muscle mass .

Best one.
5/5
Serious mass has 100% helped me put on weight. As a naturally skinny guy it has definitely helped boost my calories to ensure I reach a caloric surplus. It’s super convenient for on the go and I’ve found it best mixed with calci+ milk or almond milk for a lighter consistency. Chocolate flavor all the way.
