Rated 2 out of 5 by It's all about eggs does not work with me, I'm allergic to eggs, have too much albumin 31 March 2016
Rated 4 out of 5 Great price, good quality The item is very good and benefit me good, although the scooper is bigger than the lid so a lot of the product falls out. I would recommend getting a new scooper 06 March 2016
Rated 5 out of 5 by Excellent product Very pleased with this product , tastes great . Would definitely buy this again. 01 November 2015
Rated 4 out of 5 by Greate taste A protein shake with a great taste ,possibly best on the market at present that I've tried . Not only this but with a decent amount of protein in it. Only downside is the scoop is too big for the lid hole however would fully recommend this product. 11 October 2015
Rated 5 out of 5 by exactly what it says This stuff is seriously good, chocolate flavour is recommeneded. If you cant gain weight with this product, i suggest you look into nutrition or learning to eat properly or your just throwing money away. Like others are saying though the lids far too narrow for the oversized scoop/cup that it comes with. resulting in loss of product half the time and a whole lot of mess on your kitchen worktop. Also hard to mix with your normal shaker cup, i strongly recommend using a blender. but overall i am extremely happy with the product as it done exactly what it intends. 18 July 2015
Rated 5 out of 5 by This product has great features Great value for money. Does exactly what it says on the tin Each serving of Serious Mass contains 1250 serious calories ... you can't go wrong with this !!! 05 February 2015
Rated 5 out of 5 by Great for slim guys wanting to bulk up This is expensive (for me) but the reason I bought it was because of what it said on the label, I wanted a high carb shake and was not too concerned about protein (althogh protein content is still good) Also, unlike cheaper shakes online, these carbs are not all sugars. I have not had great success in the past but in a week I went from 71 to 74-75 kilos, I have never seen 75 kilos on the scale in my life so I am over the moon and will be buying another one :) I had three single scoop shakes every day. The scooper is a bad design because you cannot get it out the container without also spilling some (its too big) It worked so I will be returning for more even though the price is a lot. 10 May 2014
Rated 4 out of 5 by Large amount of calories I bought Serious Mass because I want to get mass.Its rich in calories and protein.All I need.Its also easy to shake with out any lumps 23 January 2014
