Finally! A shake that actually tastes amazing and works.
I’ve been through dozens of different brands, but this is hands down the best-tasting meal replacement I’ve ever tried. Usually, you have to choose between "good macros" or "actually drinkable," but this managed to hit both. I’m genuinely impressed. The Taste & Mixability: The flavor is incredible—it’s rich, smooth, and doesn't have any of that weird, bitter aftertaste you usually get with "diet" products. But the biggest win for me is the texture. I just use a standard shaker bottle, and it mixes perfectly every single time. No annoying chalky clumps, no grit, just a perfectly smooth, creamy shake. It honestly feels more like a dessert than a nutritional supplement. How it feels: It’s surprisingly filling. I’ve been using it to replace my lunch during the work week, and unlike other shakes that leave me reaching for snacks an hour later, this actually keeps me satisfied until dinner. It’s thick enough to feel like a proper meal, which makes a huge difference mentally when you're trying to stay on track. Why I love it: • Best Taste Ever: Genuinely look forward to drinking it. • Perfect Consistency: No blender required; it’s smooth just from a shaker. • Zero Bloat: Usually, these things make me feel heavy, but this is really easy on the stomach. Verdict: If you’re on the fence because you’ve had "cardboard" shakes in the past, give this a go. It’s worth every penny for the flavor alone, and the fact that it actually kills my hunger is the icing on the cake. I won't be switching to any other brand after this!

My go-to shake and the best tasting I’ve tried
This has become my go-to shake. I’ve tried quite a few meal replacement and protein shakes over the last year, and this is easily the best tasting one I’ve found. I’ve been using it consistently for over 8 months now. I feel full after having it, and it’s fitted really well into my routine alongside regular exercise. I’ve lost over 3 stone during that time, and this has helped me stay consistent and make healthier choices overall. I’ve also found it helps with recovery after gym sessions. I usually mix it with ice, which gives it a really good consistency and keeps it nice and cold, exactly how I like it. It blends well and doesn’t end up thick or gritty. I’ve tried a few other flavours in the range too, but the vanilla is my favourite. It tastes much more natural than a lot of vanilla shakes on the market, which can be overly sweet or artificial. The only small downside is that the scoop can be a bit tricky to find when first opening a new tub, so I tend to keep one from the previous container. Other than that, I can’t fault it and will continue using it.

Tastes like vanilla and strawberry is nice, but not 100% Keto friendly
Just tried it today as I am going Keto agan, but this isn't Keto. It tasted okay, however (TMI) I had a bowel movement after wards, so jury is out, not sure its good for my gut condition and IBS. I have ordered the strawberry one. Really a shame Exante aren't doing shakes anymore, as their vanilla Keto was the best. This tastes similar to Exante one, but it's protein. As a meal replacement to get me back onto fasting in general before I do Keto eating, this is a good solution. Has nutrients I need and saves time. WIll do an update later. UPDATE: Srawberry one is really nice.

Perfect Lunch Replacement for Consistent Weight Loss!
I am now on my third order of the USN Diet Fuel Ultralean Vanilla Meal Replacement Shake, and it has been a game-changer for my diet and weight loss goals. I use this shake religiously as my lunchtime meal replacement, and it works perfectly. • Keeps Me Full: The high protein content—25g per serving—and added vitamins genuinely make me feel full for longer. This has eliminated my afternoon snacking and greatly aided my consistent weight loss. • Great Taste: The Vanilla flavour is delicious and makes it easy to stick to. It’s simply prepared by adding 2 scoops to cold water. • Nutritionally Sound: It's a convenient, low-calorie way to get my essential vitamins and nutrients. • Convenient & Versatile: This 1kg powdered drink mix is quick to prepare and can even be made up as a snack between meals to curb sweet cravings. If you are looking for a reliable, tasty, and effective meal replacement to help support your weight control and weight loss journey, I highly recommend the USN Diet Fuel Ultralean. It’s definitely helped me see consistent results!

Flavour
Really great flavour not at all chalky.

Doesn't taste the best
I purchased the vanilla flavour. It tastes quite powdery but has a distinct vanilla taste. You can make it up to your own consistency using between 250-300mls of water, I went with 300 and it was still thick but just about right for me. Very quick and convenient. Can't comment on the weight loss as I have only had 1 day's worth so far. I feel satisfied and adequately filled, just snacking on fruit and drinking water between shakes. I dislike the amount of packaging for the tub being only half full of product, seems very wasteful and unnecessary. Will purchase again if satisfied with the weight loss

Not bitty or grainy like a lot of others
I’ve tried a couple of products but I found this one not to be bitty or grainy at all. The vanilla flavour is quite nice this product did not leave a nasty aftertaste. I did mix the two scoops with my 300 mL of water in my blender. but 30 seconds in the blender made it to frothy but was still very nice to drink

Usn diet fuel protein powder
I find this vanilla very sweet so I add more water or just one scoop instead. I blend in my nutibullet with 1 raw egg, a scoop of oats, & tbs of chia seeds. This keeps me full for 4 hrs. I get up at 415am work and have it at 8 or 9am and keeps me going till lunch. I lose a pound a wk average. I'm very active in my job. This curbs my hunger. B4 I was eating every 2 hrs. The only thing I don't like is the massive tub only half full of powder. Hard to store and deceiving to the buyer.
