I used this in conjunction with a high calorie diet while I was trying to pack on some quality size. Being a hard gainer, even eating a tonne of food didn't do too much for me. So with O.N. Serious Mass I was blown away by the quality of the calories. Most weight gainers i've tried previously have an extremely sugary taste, or have an odd paste taste. O.N. was leaning more towards the paste side, but still I was able to enjoy the flavour. It might just be that I don't like to use too much liquid, i'd rather a smaller, thicker drink, than a smooth, but twice as much gainer. Along with the extra calories I was trying to consume with my high activity job at the time, it just made for easy calories when it wasn't viable to sit down for 30 min and eat a protein/carbs/fats meal. I'd definitely recommend this to anybody trying to put some size on without having to drink pure sugar for 20 minutes.

I have tried the ON Serious Mass chocolate and vanilla flavours. The vanilla is by far the best. It mixes reasonable easily and the vanilla is a great flavour to blend with fresh fruit. The formula has a comprehensive list of supplements added - vitamins, amino acids and minerals. By far the most comprehensive of any mass gainer. I have tried this as well as Mutant Mass (still have half a bag of MM left - terrible taste). You will gain weight on this product. I use it as a meal replacement by blending with fresh fruit, yoghurt, yakult, non-fat milk and coconut water. Like the effect of a lot of these supplements, you might get diarrhea.
