Review: 62p a shake. The maths speaks for itself. - Not only do these taste absolutely incredible (tried Strawberry, ordered Chocolate to try as well) they work out at 62p a shake (2.5kg tub), 200 calories a hit. The maths speaks for itself. If you take two of these and a light tea, you're losing weight. If you have a light breakfast and two of these for dinner and tea, you're losing weight. If you have three of these plus multivitamin tablets no big meal, you're losing even more weight. It's a win win. Obviously don't try these if you haven't got the discipline to avoid ordering a takeaway at 10pm. These will work, the maths doesn't lie... 400 calories across two meals means + 25grams of protein per serving, you'd have to have a huge meal elsewhere to not see benefits. This will be a regular for me going forward. Cheap imitations (X-tone for example), don't come close. A little pro-tip, Home Bargains sell the USN Select for 12.99 a tub. It's not as good as this, only 20g of protein per 200 calories, but if you're desperately in need and want to avoid hitting the snack bar at work, you can grab a tub from there. I have, very useful for those days I don't have access to my usual tub. UPDATE: So I've now tried Strawberry, Chocolate and Vanilla USN Ultrealan and also Strawberry and Vanilla USN Select and feel compelled to rank them in order. I blend all of mine using a Blendjet or standard Protein shaker 1. Strawberry Ultralean - For me, this is the king. It tastes amazing. It's like smooth angel delight. Fills you up for ages. 2. Vanilla Select - This tastes absolutely amazing. It's probably the nicest taste of all of them, but it's a little thinner which means it might not fill you up quite as effectively. Taken with supplements to bulk it, I find it perfect during the day at work. 3. Strawberry Select - Tastes pretty good. More like a traditional Strawberry milkshake, and doesn't fill you up as much as Ultralean but still a really good product. 4. Chocolate Ultralean - Thick and fills you up for ages. Probably the thickest of all of them and very effective at keeping you full. A little bit on the sweet side and your second in the day can seem a bit sickly. 5. Vanilla Ultralean - I might edit this review if my opinion changes, but at the moment, this feels the biggest disappointment. After tasting Vanilla Select and noting how amazing it tasted, I had high hopes for Vanilla Ultralean and figured it would be the same flavour but perhaps a bit thicker. It has this weird chemical flavour going on (a common theme in these reviews). It even smells a bit chemically, at least from a distance. As it stands, I'd probably avoid the Vanilla Ultralean and advise that Chocolate Ultralean is an acquired taste but happy to stick with 5* for Strawberry alone.
Review: 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

## Questions & Answers

**Q: Roughly how long would a 1kg tub last having 1or 2 shakes a day?**
A: Sorry if this come across as patronising but some of the arithmetic previously posted is at best, very dubious. 
The full tub contains 1Kg (1000g) of powder. It takes 2 x 25g (i.e. 50g) scoops in about 300 of water or skimmed milk to make one shake. 1000/50 = 20 so a tub makes 20 shakes. If you have 2 shakes per day that means the tub will last for 10 days. If you plan to do this for a month, you will need 3 tubs. I recommend one of each, chocolate, strawberry and (my favourite flavour) vanilla. Dont forget to have a ballanced meal (preferably at mid day) and you will still also need to do some exercise to lose weight effectively. Hope this helps.

**Q: How many servings is in the 2kg tub ?**
A: just so people know. a scoop is 25g and two scoops is 50g. the scoop that comes with it when full is 50grams  . so don’t put two filled scoops in. just one scoop. 
it says on the back a scoop is 25grams
if you look on the scoop it says 50grams on the inside.

**Q: Does it keep you full and if so for how long?**
A: 5 hours keep me full i drinking 7am day starting  12md like a lunch and 5 o clock I eat my health meal

**Q: why can't you sleep when you use it at afternoon or at night? Is there any thing that disturb your sleep for example the energy with it?**
A: I've often had my shake after 6pm and it's never affected my sleep. Check the list of ingredients, it may help.
