Review: Absolutely fine, what else do you need? - Some weird reviews here. Its protein powder, not a Michelin star meal. Taste? Fine. It isnt like a salted caramel cheesecake, but neither is it objectionable Consistency? It mixes with water and milk. What else do uou need. Value for money? Yep.
Review: Top Product - So it was with some trepidation that I ordered this protein after reading the negative comments made about it, but I wanted to find a protein powder at a better price and I have, hands down. Very large tub that was well packed and delivered with the usual desertcart speed. Paired it with a cheap shaker mixer cup { with metal spring ball } I placed cold water { 250mls } plus the ball and dumped 1/4 cup of the protein powder into it, a good shake produced a smooth drink with no lumps, grit or sludge { unlike some others I've used } the taste was good, { chocolate and peanut butter } and very easy to digest, its been over a week building up to two shakes a day { this helps with the dreaded protein wind } but you already know about that if your a regular protein drinker ! I have not tried the powder any other ways { milk etc } so this maybe where others are having trouble mixing it, its great simple way to take extra protein and at this price I will gladly re-order when needed, only negatives I can say is that mine didn't come with a scoop { no big deal } and that I had to find a home for the large tub { out of the dogs way }

### ⭐⭐⭐⭐ Massive Value for Money, Taste is Acceptable
*by C***N on 19 November 2025*

I picked up this 4kg tub of the Salted Caramel "Serious Protein" primarily because of the price-per-serving ratio. With 133 servings listed on the tub, the value proposition is hard to ignore compared to smaller premium brands. After working my way through the first kilogram, here is my honest breakdown. The Packaging & Size First off, be warned: this tub is enormous. It barely fits in my standard kitchen cupboard. If you have limited storage, you might want to decant this into smaller containers. The lid seals well, which is crucial for a bulk buy this size to prevent the powder from clumping over the months it takes to finish. Flavor & Texture (Salted Caramel) With Water: It mixes relatively thinly. The flavor is sweet, perhaps a little artificial on the aftertaste, but drinkable. It doesn't have that thick, milkshake consistency when mixed with water alone. With Milk: This is where it shines. It becomes much creamier and the "salted" note comes through better, masking the artificial sweetener taste. Mixability: I use a standard shaker with a metal ball. It mixes about 90% well, but I do notice occasional small clumps if I don't shake it vigorously for a good 45 seconds. It's not the finest milled powder I've used, but acceptable for the price. Nutritional Value For a "Serious Protein" blend, the macros are solid for lean muscle support. It is low carb, which fits my current diet macros well. However, note that this is a soy/whey blend (check the ingredients label carefully), which explains the slightly different texture compared to 100% Whey Isolate.
