## Customer Reviews

### ⭐⭐⭐⭐⭐ Tastes great
*by W***E on 2 November 2024*

Good taste, I mix it with skimmed milk or put it in my Greek yogurt.Mixes well. I just use a spoon.Decent quality, but cheaper buying direct from protein works.

### ⭐⭐⭐⭐⭐ It works, 2st lost
*by S***H on 6 June 2020*

I've used ' diet whey ' products before, as meal replacements, breakfast and lunch at work and sensible evening meal at home and to be honest I always lose weight really quickly but get bored and give up. This one is just pure protein with no carbs at all hardly, no sugar no fat, I don't know if it's a proper 'diet ' whey or extra protein for bodybuilders but it definitely works and I'm not hungry at all even during a day of hard graft on the building site. Only negative is the vanilla flavour is really sweet but that's just nitt picking and I'll definitely be ordering the chocolate next. EDIT I must add that having this shake for breakfast and lunch and a cooked evening meal from may 2020 to august 2020 I have gone from 20st to 18st without really changing anything I do. I'm a stone mason on building sites so I class that as my exercise 🤣

### ⭐⭐⭐⭐ Protein
*by C***S on 28 May 2025*

Always use this after every run, pleasant taste too, silk chocolate
