Using it for years
Been using this product for years... Started at £25 about 7 years ago obviously due to British pound going down in value the price has risen. Still a good price. High carb shake with minimul sugars. I have bought similar products from Holland and Barrett and The sugar content is half the carb intake. I went from 10st to 17 on this in few years I have been taking. I bulk in winter and this helps... after a high calorie breakfast I also down one of these. People say it doesn't go well with water. No protein shakes you will ever take will taste well with water. I use 350ml water 250ml milk and it tastes good! I did a bulk last year I was 15.5st and went upto 18.5 by summer. I gained 1st extra in muscle. I went down to 16.5 off bulk and stayed at that weight even on The cut. I have around ,18% body fat. 22in winter. Also buy serious protein to add that extra 25g to the protein intake. 1.5-2g of protien per kg of body weight. If you not making gainz then you probably not doing this. This product has helped me a lot through out the years and I stand by serious protein and serious gainz to make my gainz.

Pretty Good
Just started with Protein powder again after workouts. I’d used the Amfit stuff at first which was good but I thought I’d try a bigger Bulk tub. This was on offer with a further 10% off so a real bargain. Comes in the big black tub with snap seal and a scoop. Each scoop gives decent Carbs and Protein for your after workout/run nutrition. I got the strawberry flavour which is reasonably palatable, so of the powders are truly awful but this is pretty good. I have noticed if you make it up and leave it for a while it does develop a strange taste and texture so I tend to mix it up as I need it. It comes in various flavours which I haven’t tried but if they are the same as this one they will be good. I mix it with water, not tried milk but I would think it would be even better with Milk. All in all I’ll definitely buy again and at this price you can even double up if required.

Decent protein powder for the price
Mixes well with no clumping, the cookies and cream taste is generally good, but there is a powdery gritty aftertaste which I'm not keen on. I can deal with it for the price as I can't afford the prices of the optimum nutrition protein powder now both me and my son are using it.

Disappointing
I've been using protein supplements for years without any problems, mainly sticking to trusted brands like Optimum Nutrition and Bulk—both of which have worked really well for me, aside from being a bit pricey. This time, I decided to try something new because it looked good on paper and was more affordable. I gave it a fair shot—used it consistently for almost a month hoping my body would adjust—but honestly, it's been one issue after another. I don’t usually leave reviews on Amazon, so the fact that I’m writing this should tell you how strongly I feel. I just want to help others who might be thinking of switching to this brand for the first time. Here’s my honest take: 1. The value for money and the nutritional profile seem decent at first glance. 2. The taste is poor—grainy, doesn’t mix well, and has a chalky texture. 3. It doesn’t sit well with my stomach at all. I’ve felt unsettled after nearly every use. 4. It feels more like I’m taking medicine than a supplement—no enjoyment in it whatsoever. I regret trying to save £10 with this purchase. It just wasn’t worth it, especially since I’ve noticed fewer results compared to when I used Optimum Nutrition or Bulk. If this product works well for you, that’s great—everyone’s different. But if you’re considering this as your first protein or thinking of switching brands, I’d recommend proceeding with caution. Thanks for reading—hope this helps.

Cookies & cream tastes like play-doh
Cookies and cream tastes like play-doh 🤮 I will be adding milkshakes to alter flavour for me personally this time around, this brand is missing something with the flavouring compared to other brands just not as nice, so far had vanilla now cookies and cream, taste nothing like other brands, it was cheap so for that reason I'm rating 3 stars

Thought I’d try a different protein powder and I’m sure it will do the job, But it does not mix well at all and there is very little in the way of chocolate taste. In fact it doesn’t really taste that good as you can taste more of the oat based ingredient. Find a different protein powder to buy and I’ll be going back to my usual one.
