Rated 4.8 out of 5 by 4 reviewers.
Rated 5 out of 5 by Great taste/Perfect for gaining weight/Use blender It tastes great but I would recommend using a blender instead of a shaker. When I use my shaker it usually leaves some pieces of it inside the bottle. 23 March 2016
Rated 5 out of 5 Great product with a quick delivery . I highly recommend it! 18 February 2016
Rated 5 out of 5 by Very good Very good product and tastes lovely! It's a little bit of a pain with the size of the scooper however, very satisfied with the product, timely delivery and service throughout. 15 February 2016
Rated 4 out of 5 by Great brand I always use Optimum Nutrition because of its quality. However I accidently got this serious mass instead of gold standard whey so I was a bit surprised to see the size of the spoon and taste. its a lot thicker in taste which makes sense i guess because of the calories per serving! Strawberry flavour is better than chocolate.This product is great if you want to gain quick 13 January 2016
