Good value and mixes well
I brought this to use in conjunction with their Whey protein. This is a better solution to having to consume a pot of cottage cheese before bed time. I have also started using it before I go to work. My shift work affords me very few opportunities to eat especially with no scheduled breaks. I tend to graze and this slow release protein helps to keep the amino acid levels topped up throughout the shift. The taste isn't great but palatable. It's more like creamy coconut with hints of vanilla. Mixes into a thick solution. I use 200 ml milk with 100 ml of water. Produces much less froth than milk alone. I also use a scoop and a half. Mixed using a Maximuscle shaker, and shaken for about 10 seconds. I'm pleased with the results but haven't tried any other Casein proteins.

Amazing!
Best casein I’ve tried so far, vanilla is definitely better than chocolate. Tastes better and is a lot smoother while chocolate has that grainy texture so I won’t buy that flavour again.. It is a bit better if I shake it with a spoon of peanut butter but if you’re thinking about buying it, I’d recommend vanilla over chocolate any day! I’m also lactose intolerant and this is so far the only casein I’m able to drink without any issue.

Good product
Can’t fault the fact that it does keep me feeling fuller for longer, as I don’t eat when I’m working (I’m a carpenter). But compared to normal whey protein this stuff is very dry tasting and a little powdery. Also it’s a super fine dust that sticks to absolutely everything if you spill it 😂 besides that it tastes good and can feel a difference

You've got to be joking
What in the hell happened? This used to be the best Casein on the market a few years ago, bar none. Now it's all full of lumps, poor taste and overpriced. Seriously, you've got to be crazy to still pay this much money for a similar quality 20£ protein powder. Company has gotten cocky, hopefully people realise this is utter garbage and the market normalises. £80 low quality protein powder oooofff. LE: You are legit taking the piss with the prices of this and Whey Protein.

My favourite product
The powder is fantastic. Creatine does not agree with me at all so I have upped my protein intake drastically and this product gives me exactly what i need. When you are lifting to get big and ripped anyone in the know will tell you that periods of fasting are absolutely the worst thing you can do and when do you fast for longer than when you are asleep? When taken before bed with water this product increased my raw strength and lean size drastically, not to the same extent as cycling creatine but as i've said, there are serious side effects to use of creatine if you are sensitive. If i was asked to quantify i would say that this improved my results by at least 20% and don't be put off by the price! There is no substitute for milk proteins and a combination of casein in the morning and evening and whey pre and post workout is the best you can give your muscles. You'd have to eat a tin of tuna to get the same amount of protein as you do in a serving of this and its massively inferior protein at that!

My go-to casein – amazing vanilla flavor!
The vanilla flavor of Optimum Nutrition Gold Standard 100% Casein Protein Powder is hands down my favorite. I’ve tried a lot of casein powders, but this one just hits differently—smooth, rich vanilla taste without being overly sweet or artificial. What I love most is how versatile it is. I use it in pancakes, French toast, and pretty much any kind of baking, and it always turns out great. It adds a nice flavor and texture without making things dry or chalky. Even mixed just with water, it tastes really good, which honestly surprised me for a casein protein. The consistency is creamy and satisfying, perfect as a nighttime shake or snack. This has become a staple in my kitchen—I keep repurchasing it. If you’re looking for a high-quality casein with a delicious vanilla flavor, this one is definitely worth it!

C'est une caséine, elle est digeste et extrêmement agréable à utiliser.
C'est une caséine micellaire. C'est bien ce que je cherchais. On ne sait malheureusement pas d'où viennent les matières premières, ce qui est le cas d'une bonne partie des produits de ce type. Ceci dit elle est très digeste, ce qui est un excellent point, étant donné que ce n'est pas forcément gagné d'avance. Vous verrez beaucoup de gens devenir "intolérants" aux protéines laitières, plus à mon avis qu'avec les produits dont on disposait il y a vingt ou trente ans, qui étaient pourtant théoriquement moins "high tech" (mais étaient souvent majoritairement constitués de caséines, justement et non de whey comme aujourd'hui). La cerise sur le gâteau c'est que c'est une protéine vanille avec une texture crémeuse, un goût pas trop chimique et que ça donne quelque chose de très agréable à consommer aussi bien sous une forme plutôt liquide ou sous forme de crème (avec tous les intermédiaires possibles). Elle me semble d'ailleurs meilleure sous cette forme, et c'est là qu'on est heureux qu'ON n'ait pas eu la main trop lourde sur les édulcorants. C'est mon goût, je sais que certains ont du mal avec la texture des caséines, mais j'avoue ne pas bien comprendre pourquoi. La vanille, il faut le rappeler est le parfum le plus versatile : on peut faire des milk shakes aux fruits rouges, ou à la banane, selon les goûts. Le parfum est présent mais s'efface devant à peu près tout ce qu'on peut mélanger avec. C'est pratique. Le chocolat n'est pas extraordinaire, mais reste buvable. J'ai testé un mélange avec la whey ON vanille et la caséine chocolat, c'est sympa, plus que le chocolat seul donc. Une protéine pratique, facile à consommer et peu agressive sur les intestins (en tout cas pour moi) plus que d'autres, en tout cas. On augmente bien sa consommation de protéines avec sans problème(s). Mélangeable avec une whey pour avoir une protéine "à l'ancienne" mixte après l'entraînement ou le matin. En collation avant l'entraînement (1h environ) semble aider à maintenir un bon niveau d'énergie, même au régime, plus efficace à mon sens que des BCAA pour ce genre de chose et aussi efficace qu'un mélange peptopro / maltodextrine, les calories en moins. Bonne protéine de régime donc, comme de prise de poids, sans doute. Je recommande. Bon produit à tous points de vue.
