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!

Quantity and taste.
Give star because the package was intact, no spill and not damage. Also because it’s really big. I just tried the chocolate flavour taste nothing like chocolate but I like it, I didn’t want an overpowering chocolate flavour anyways. The sim is to gain weight so fingers cross, also it’s really thickens when missed with water or any liquid omg 😦, I think it’s best to mix with a blender for best results . And I got a little extra creatine gift thanks

Great for muscle growth, but with A LOT of carbs.
I started using this after a severe acute spinal condition and emergency spinal surgery left me with around a 17kg loss of lean muscle mass. Once I had a go-ahead to exercise safely, I got back to the gym and got into serious weight gain territory. After 3 months I had gained 7kg of visible lean muscle. I’m 66 years old, so wasn’t expecting any rapid gains. My gym routine and strength progressed rapidly, and the muscle growth continued, but I’ve noticed my body fat has also started to increase, so I’m switching to Serious Protein from here on out, to lower the level of carb I’m taking in. Sugar content in the ‘Gainz’ product is seriously high, and will add to your body tissue makeup, as it has with me. The whey protein route is widely accepted as great for muscle building support, and both products tick that box. Quality and flavour are faultless, although I suppose flavour is a very subjective topic. The powder mixes well with water or semi-skimmed milk (for extra protein) in any decent protein drink shaker. The lid seals very tight, so the contents stay fresh for as long as the 5kg lasts you. Recommended for weight gain, but might add to body fat more than you want.

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.

Very poor protein powder
Product does not mix very well no matter how long it shaken, blended or mixed. Very grainy texture when drinking or used in overnight oats.I ordered chocolate, the taste is laking any resemblance of chocolate.I wouldn’t recommend this product, pay the extra and get a brand name product.

Item packaging inadequate
Item packaging inadequate. Two of two containers were broken upon receiving, took 30 minutes to clean the mass amount of protein powder and 30% of the product was binned.

Great product but let down by transport
Good product and value for money, but let down by wastage in transport.

Terrible 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.
