Tasty/Filling/Enjoyable.
The product is fantastic.. it does exactly what it’s meant to do. So all the negative reviews given relating to this product, they are clearly not dedicated to achieving what it’s meant for. It’s not tasteless, and it certainly is not sweet, I’ve been using this product for a while now, I had to make lifestyle changes due to osteoarthritis in my hip. Loose weight was my first priority. Have the right mind set and JUST DO IT. I mix this product for breakfast with 500 ml of cold water with 1 level & 1/2 scoop of the chocolate powder. I mix in 1 tablespoon &1/2 of Oat bran with it and blend. It’s fantastic. It comes out like a proper milk shake. I sometimes have another for lunch with a piece of fruit. Normal healthy meal in the evening. Watch the calories! I have created a calorie deficit, this Usn protein has helped. BUT it also comes with exercise. I’m 64 years old and I walk everyday without fail. 3 miles at least sometimes more. I also on 4 days a week after a walk I do 30 min either on a concept 2/ Elliptical/ or spin bike. I have my own gym I tend to alternate the machines to use different muscle groups. Gradually I’ve built this up, including some strength training also. The concept 2 and movement in general has given my hip much more flexibility. To begin, it sucked, was awful. But my mind was set with my hip as it is I had to make the changes. Now I’ve lost 2 stone over quite a few weeks. I have muscles and lost a huge amount of body fat. My BP. Has come down to 125/75, from 158/90. I have got rid of all the inflammation out of my body due to making changes. Usn protein has helped me kick start this. It’s a lifestyle for me now. So I have nothing but enormous gratitude for this product. So the people who are fussy about taste, try the vanilla, it can be added with a handful of blueberries or strawberries or banana. Or even a spoonful of coffee to make a cappuccino. If I have any gripe at all , I’d say the strawberry is the most sweetest so I tend to avoid that flavour. But this product gets results. Anything done properly takes time and persistence. If you get tired, then rest, go again the next day. As your body changes so will your attitude. Package of this product I’ll agree needs to be re designed but it does not alter the quality of its contents. Thank you USN it has help me enormously.

Chocolate no good, but Strawberry is much better 👍
I normally buy the Strawberry flavour, as it's not overall sweet or synthetic tasting. I made the mistake of buying a large Chocolate version... It has an awful soy taste that is that not my cup of tea. Oh well - at least when I get to the end of it, at least I will feel like I've earnt it! Don't make the same mistake as me - Strawberry flavour is 1000% better than Chocolate. As for the product itself - I've used this plenty of times over the years and I am lactose intolerant. I use it as my breakfast and it keeps me full for quite a while and stops me snacking normally. It's better than just a regular protein shake as it has added nutrients that I would miss from a healthy breakfast. It's not a miracle product but its a useful aid if you are looking to maintain/lose weight. My current goals are to build lean muscle and I use this in combo with regular protein shakes. It does go a long way to help you manage calories and macros and most food tracker apps know the correct product information. Worth a try, always start with a small batch first to see how you get on.

Thick and filling
2 scoops blended in water, mixes perfect, smooth texture and tastes brilliant not over sweet. Very filling, keeps me going for hours. Brilliant if your on a diet, 2 shakes per day and low calorie meal the weight will fall off ! Think this is probably my 5th tub. Well worth the money

Great product, but add more water (Lost 19.5lbs in 12 weeks so far)
TOP TIP: Mix with 450ml of cold water rather than 200/300ml recommended in the instructions. This is a very good product, I've been using the chocolate shake as the foundation for a diet since the beginning of Feb this year and I've lost 19.5lbs in 12 weeks. This is with 2 hours exercise (generally once a week, sometimes twice). I wasn't massively overweight but over the autumn/winter (and also the last few years) my weight had crept up and my BMI had gone from a healthy range for my height to a bit overweight. In the first few days I found ultralean a bit sickly and after reading the reviews on here I wasn't sure how effective it would be and thought about stopping it. I then increased the amount of water that I add to the mix from 300ml to 450ml. For me this improved the shake massively and I quite enjoy it. It has stopped me feeling hungry and I haven't had any negative side effects. Routine: I've been having a shake for breakfast around 6.30am, which gets me through to lunchtime (12.30pm-ish). During the first weeks of the diet I also had a shake for lunch (in addition to the breakfast shake) and a normal meal in the evening. Some weeks in I switched to fruit or a 'berry-good bircher' from Starbucks for lunch. I've now refined this further and I'm making my own Bircher from a traditional German recipe. I've gone from 11st 10.5lbs to 10st 5.5lbs in 12 weeks which is an average of 1.6lbs a week (I've been aiming for 2lbs a week). I still eat a normal meal in the evening. As the diet has progressed and I've been looking to hit weekly targets, I've also reduced the amount I drink (alcohol wise). I'll maybe have a few beers or glasses of wine over the weekend, but I'm not drinking during the week now. For me the main takeaway is, just add more water to the shakemix - it does work well despite some of the other reviews. Motivation is key, I found a weight loss competition with a colleague from work has also helped massively. The great thing with using the shake is that it give you a system that you can just rinse and repeat, you always know how many calories that you've had. I'm looking to lose a few more pounds over the next week but I've already hit my target and I haven't been this weight since I was 22.

This product used to be better in 2015-2017 Should be £26 not 30+
The good years of protein shake, this tasted better back in those days and they had cafe latte versions and banana and caramel, I think that one is still being sold but it shouldn't cost more than £26 for 2KG as that is what I used to pay back in 2015 and 2017 flavours were better value for money was cheaper to buy back then I mean it really was better times, so now we in a crisis of bills and payments and what do these companies do? They put the price up to 30-37+ quid for 2kG quite a harsh scam if you ask me for something that doesn't taste as good as the old USN diet fuels and to put the price up on it? It is not even Vegan product! These companies getting too greedy, but if we all stop buying they will reduce the price trust me. This has poor value for money and reduced taste and quality of the chocolate and strawberry flavours, the only one that stayed the same was the banana and caramel but that price jumped as well. Used to use these in between meals or to have in the morning and not eat anything until evening as I was doing my intermittent fasting to save money and be healthy at the same time. Of course I can't really be healthy if I'm drinking these protein shakes as all protein shakes are an unhealthy byproduct of human creation.
