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.

HELL YEAH!!
OMG 5 kilos of it!! Absolute bargain!! Ok so I have used it It mixes very easy, not as thick compared to some other shakes but not a problem, it has good protein to carb ratio The flavour yeah it is chocolate-ish but although not heavenly chocolate it is very pleasant to drink, if you wanted to make it really chocolatey get some raw Coco from the shops and mix it in I am thrilled to bits omg 5 kilos of it 😃😃 All in all well worth the money, tastes better than more expensive ones I’ve bought for much less, I will definitely purchase again ...hmmm if only they had Raspberry ripple 😋 10/10 for the amount 5 kilos 😲

What you'd expect.
It's not bad, mine arrived damaged (tub split open) but fortunately I had an empty 5KG of USN to transfer into but that's nothing to do with the product itself... It mixes sorta well, you'd want to shake it up first and then wait, you'll notice a heavy layer form at the top, when you see that shame again and drink immediately. Taste is sorta chalky and nothing super special, it's certainly drinkable and to a minor degree somewhat enjoyable. Protein macro is kinda weak but it's a bulk shake so what you expect I guess? Would've been nice actually if the product was amino acid spiked with creatine so it had a bit more use but hey-ho.

Terrible powder, flavour and does not blend.
Waste of money, the powder hardily blends into a shake even after thoroughly blending. Weak chocolate flavour and just leaves the powder around the inside of your mouth after each drink. This is a poor product and would not recommend to anyone.

Great value gainer. I like it!
I've been using this for about 3 weeks now and really like it. It's cheap, decent quality, and does the job. The tub was fully sealed unlike some reviewers. I bought the chocolate flavour. It's actually quite nice and a lot better tasting than most powder shakes. Not sure how those who are complaining about the poor mixing are blending theirs, but I use my Nutri Ninja blender and it mixes great. If you don't drink it fairly quickly you do get a little sediment at the bottom (and I mean a little) but a few swirls of your drink container and it's fine. It's easy to get down. I weighed it out and find 4 flat scoops in 500ml of water gives you the 125g you need for 468 calories and 30g of protein. If you wanted to to use 500ml of whole milk instead then that's going to give you an additional (approx.) 300 calories and 17g of protein. So it really depends on how many surplus calories you're needing to start gaining. I've been doing a lot of cardio recently so I have found this gainer actually just keeps my weight consistant - which is great. I know if I wasn't doing cardio then I would definitely have gained weight. I currently have one shake a day but I may increase that to two soon. I expect to see a gain then (will let you know). Remember that this is a food supplement to add surplus calories and protein to your diet. Not some miracle powder. It does what its designed to do. Bar that, I've experienced no ill side effects. No bloating or excessive gas. So no complaints from the other half. If I suddenly go blind or grow an extra testicle in a few weeks I'll let you know. All in all I'm happy with it and think it's great value. I'll definitely be buying another tub!

Not for me.
You get your moneys worth with the quantity, but I’m not a fan of it. I’ve used a shaker bottle, mini blender and a proper blender. It leaves a horrible layer at the back of your throat. I don’t find it easy to drink if I’m honest. The flavour doesn’t really blow your mind either. I’ve only used it for a few days, so I don’t think it would be fair rating its effectiveness. I’m not going to buy again just because of the layer of powder it leaves in your throat.

My second order
This was a reorder for my son he swears by this product for maintaining a good balance in his diet, he is not a body builder but just likes to keep his calories up or he becomes to thin, he say it's brilliant and like the taste.

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.
