Idk where you're from but I love Bulk whey protein powder White chocolate flavor. It tastes so milky! And goes better in sweet recipes than vanilla
I like the MyProtein clear whey as well. I currently have Cola Chuppa Chupps flavour in my water bottle 😂 I like their original vimto, Strawberry Chuppa Chupps, Raspberry Lemonade and the Peach Tea I’ve only tried once from a sachet
I like the Bulk protein powders and ‘Bulk Week’ is currently on so they have discounts. I use Vanilla, Chocolate and Salted Caramel - although now I have a Ninja Creami they are almost exclusively used for high protein/low cal ice-creams which taste amazing. Approx 22g protein/122 cals/32g scoop MyProtein do a MarsBar and a Snickers protein powder I also use the MarsBar one to make amazing ice cream.
A really good protein powder makes all the difference. I use Bulk Pure Whey Protein in mine and I’ve also used MyProtein MarsBar protein powder. Bulk flavours used - Vanilla, Salted Caramel and Chocolate. I find I don’t always need a sweetener as the protein powders can be quite sweet already. However if adding a sweetener I use the sugar free calorie free coffee syrups. Are you using a thickening agent like Xanthan gum? Really makes a difference to the texture and consistency
Bulk Supplements - Natural Pure Whey protein. It’s the only one I’ve found which tastes njce and has stevia as a sweetner. I’m sure there others but I’m sticking to this.
Allgemeine finde ich die von Myprotein und Bulk sehr gut. Ich habe gerade slayed caramel Schoko von Myprotein die ich gut finde, mein Frau aber nicht. Von Bulk gab's Schoko Cookie, die ich super fand. Bulk hat auch die beste Proteinmischung, mit 4/5 verschiedene Quellen.
I honestly can't remember why I first tried them, but I've used others (Applied Nutrition, My protein, others) and the stuff I've had from Bulk doesn't seem any worse, and I get it cheaper. The ingredients are all solid
I use Bulk's (the UK Bulk, not the US one with a similar name) "pure whey", the unflavoured 'natural' one as it's good value, doesn't have any sweeteners or additives, and is vaguely milky. Though I have to add that though it's relatively cheap, I use it more to enrich a cereal or the like or as a fallback - my major sources are skyr and quark, so high protein fermented dairy products that are both cheaper and (for me in Germany) an everyday food item, about 55-65 cal for 10-13g protein. An alternative here is "Protein milk" from Schwarzwaldmilch, it's a high protein UHT milk that's 75g/L, so 3x protein shakes per carton in effect.
Simplest thing is to go for unflavoured, unsweetened whey. Bulk in the UK does good "neutral"s, I find something vaguely milky far nicer than any of the flavoured ones. You can, of course, flavour them yourself with cocoa powder or coffee essence or vanilla extract or something else you like.
