Optimum Nutrition Serious Mass review by Aprilia

July 12, 2014
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.
