Tastes great
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
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 🤣

I really like this protein powder
I really like this protein powder, I switched to this from Promax because it's overpriced and I think the brand has lost the plot. This has a higher protein content anyway and none if the bulking agent other powders use just good quality whey. I find it mixes very well and tastes pretty good for a protein shake. I've only tried the chocolate silk so far but will try the other flavours. Nice quality resealable bag too, I was sceptical but find it works better in the cupboard than a massive tub.

Wish I could give it 5 star.
Nutritional Values are amazing, probably some of the best I've found. I feel bad to give it 3 stars as it is a product I will buy again, but other than the nutritional values the taste is edible/drinkable at best (cookies and cream) and it mixes quite badly. The price is not that bad considering it's a whey isolate, but for around the same money, there are way better options if you are not cutting.

great product
For me, Ingredients are most important as I want to know what I consume. This product has, after many researches won and its already the second bag I purchased.

Now cheeper to by direct from manufacturer
I quite like the cookies and cream, its definitely drinkable and definitely helps to boost my protein intake. But after buying my first 1kg packet for around £29 just a few weeks ago, i know see that Amazon have changed the price to £44. Its only £35 including postage direct from the manufacturer. So sorry Amazon until you stop trying to rip people off then i won't be buying it from you any more.

Habe das Produkt schon mehrmals in der Geschmacksneutralen Variante gekauft. Geschmacksneutral ist es ein Top Produkt, die Werte sind gut und es schmeckt halt nach nichts. Perfekt für mich. Jetzt war das aber ausverkauft also habe ich den Schokoladen geschmack gekauft, der geschmack ist so ekelhaft und schmeckt so extrem künstlich das es mir sträubt nur daran zu denken. Man denkt man trinkt einfach Chemie. Sehr ekelhaft, mit Geschmack wird nie wieder gekauft und beim nächsten mal wird lieber ein anderes Produkt gekauft, wenn Geschmacksneutral wieder ausverkauft sein sollte

Bin sehr zufrieden mit der Konsistenz und dem Geschmack. Da ich kein Süßungsmittel mag und es überall raus schmecken, ist es schwierig ein Proteinpulver zu finden. Dieses finde ich sehr lecker.

I tried this with only water, and it tasted like chalk, but then I mixed it with some warm milk and it tasted really good. 250 ml of skimmed milk + one scoop = ~200 Calories/ 30g protien. No added preservatives or artificial sweeteners. Awesome

Está bueno porque lo mezclas con café o con gazpacho y tenes una bebida proteica salada. Con yougurt va excelente y se disuelve muy bien solo con mezclar con cuchara.

Con el de vainilla se forman grumos, mejor el de chocolate
