Beware for people who are lactose tolerant. Just take it at night.

Good taste
Usually casein protein doesn't exactly taste that good but I was delightfully surprised by how good this one tasted. I will buy it again for sure.

Normally ON Protein powders comes with Authenticity Secret Code to check the product authenticity, but in this product there is no Authenticity checker available. Need to confirm.

Good quality, fast delivery
Great for bed time overnight shake. Tastes like a thick chocolate shake, so if you have a sweet tooth, this also replaces your dessert. 😂

Great packaging, great results from the product! The taste is wonderful in this, the vanilla tastes like vanilla but kind of punchy and thick which brings out that flavour even more and I love that. On a muscle building point of view, this is a great product, every night I have it, I wake up the next day in a lot less pain or no pain at all. The vitamins and minerals in it are a great addition and the macro-nutrients from it including the caloric value are just perfect for me. Although I get a little bloated when I have it, I'm completely back to my normal stomach in the morning so no issues there as I can't tell when I'm sleeping. This is definitely must have product and especially this flavour over the rest. I've tried the other flavours and few other brands and till now this has been the best overall for price and results.

Me encanta el sabor. Espesa bastante en bebida de almendras. Se disuelve mal, pero con batidora o espumador de leche queda perfecto.

Casein has been a critical part of my diet since I started training on an empty stomach, usually after not eating for 16+ hours. "How is that possible?" you might ask. The answer: Casein. When milk is digested, it breaks down into curds (casein) and whey. Whey is the go-to source of protein before and after working out because it's fast acting. Casein, on the other hand, takes a long time to digest, making it a great source of late night protein leading up to hours of fasting. Why go with Gold Standard? - I personally think it's delicious, but that's just my taste. It's pretty sweet, so I would recommend just mixing with water (plenty of water, because this stuff is thick). - It doesn't have a thousand ingredients like a lot of other supplements out there. - Price Personal use: - I usually only eat within an eight hour window between 1:00 PM and 9:00 PM, and work out sometime between 12:00 PM - 1:00 PM. As my last meal of the day, I either drink some Casein or eat some cottage cheese (which is essentially the same thing as casein, but can be more expensive and more of a hassle to buy). Because it is more slowly digested, Casein keeps me full and ready to lift as I hit the gym the following afternoon. Bottom line: - Great tasting, cheap, and essential part of my diet. Highly recommended.
