I’ve tried many gainer shakes before, none taste as good or as effective as this.
The flavour is genuinely nice in this, better than 99% of the other shakes I’ve had, to the point where I could sit and drink one of these purely to enjoy it rather than get my extra calories in or macros.
Using these shakes, eating large 3 meals a day, I managed to gain 19kg in a year (My metabolism is extremely fast). And it was actually quite easy after the first couple of weeks of starting. It takes me about 3200+ to be able to gain and using the shakes made that target ridiculously easy.
Only down to this is the price, I remember it used to cost £45 at one point which made it pretty great, now I see the price bounce between £55 and sometimes £60.
Also don’t let gas out in public if you want everyone in a 5 mile radius to smell you.

The product is great and does help in gaining weight and increasing protein intake.
The product comes in a heavy plastic sack, which should be robust enough to survive transportation and damp ingress. For some reason, I keep receiving bags that have been punctured. This must occur before Amazon pack the product in the box, so some QC is needed at the packing station.

I’ve always been slim/athletic but after a serious illness I went under nine stone and stayed there (I’m five foot ten). I have a fast metabolism and eating the required amount of food to healthily gain weight was extremely difficult to sustain. I tried eating junky high calorie snacks but realised it was a stupid way of trying to gain weight.
So after buying this product I went straight in and tried to drink a full serving – mistake! I managed it but felt quite ill afterwards. I highly recommend you start with half or even a quarter serving to begin with, just until your stomach adapts. It’s now two weeks later and with trial and error I’ve found that splitting a full serving into three is best for me. One in the morning, one after lunch, one in the evening. I use full fat milk, ice cream and a banana to boost the calories per full serving to over 2000, and I find a blender works great to give a nice semi-thick smooth shake.
When I started a fortnight ago I weighed 8 stone 12, I now weight 9 stone 8, so I’ve gained roughly 10 pounds in two weeks, with fluctuations along the way. I’ve just bought another 5.4kg bag and plan to continue to steadily gain until I reach around 11 stone. I bought some weights and with some advice I’ve started a light exercise programme with the aim of turning the energy to muscle and shaping my body a bit. I have more modest aims than many who take this supplement, I’m not looking to build huge muscles and train super hard, but if you’re like me – underweight and a bit unfit – then I recommend this product along with some sort of exercise programme so it doesn’t just go straight to your belly. It really does promote weight gain, I’ve been very pleasantly surprised with the results, and will continue to use the product as needed in order to achieve and maintain my target weight.
The chocolate flavour is very pleasant, if a little sweet, and I now have no problem ingesting what I need to in order to gain weight. It may seem expensive, but at £2.50 a day it works out an easy, reliable and cost effective way to supplement your diet without resorting to less healthy alternatives. It works for skinny old me, and I don’t see any reason why it shouldn’t work for skinny old you! 🙂
Edit – it’s now 22 days after I first used the product and I’m now just over ten stone, so that’s 16lb in 22 days. People are commenting on the difference and it’s done wonders for my energy levels and appetite. So all in all I can’t recommend this product any more highly, it genuinely works. Can’t say fairer than that!
Last update – I’m now at my target weight of 11st, it’s taken 54 days for me to put on 30lbs – two stone two pounds in just under two months. That’s beyond what I expected. If I could give a final note it would be to watch your body fat as without exercise this product will raise it quite easily. I’m now going to reduce my servings to maintain this weight, with my new increased appetite it’s possible that I soon won’t need a supplement at all. So that’s me signing off, a bit heavier and a lot happier!

I’ve been using this for years and have been very happy with it and it doesn’t taste too bad

Firstly, I don’t write many detailed reviews on Amazon solely because I purchase so much from them that it would take me forever. However. Certain items (either very expensive or made to help people) will push me to write a review. Sorry for the long story, but I never tell this to people and want others to understand the struggle some guys have, and that “JUST BULK!” BS does not work for everyone. Thanks in advance to everyone who reads this and hope it helps.
I am 19 year old male, and have been skinny since… Forever. I was always bullied about my weight, and this isn’t a nice thing to live with. Admittedly, I never really had a big appetite until my teenage years (I guess because of something that kicked in at that point). I then started scoffing down very unhealthy food. Chips, chicken and chips, and burgers. From when I was about 15 till 16. I got a horrible big belly, but my arms were still skinny as twigs.
I then calmed down with the fatty foods. I still ate crisps, and to be honest, most of my lunches in my first year of college was just crisps. Then I hit my second year of college, and a friend of mine introduced to me gym. Much later than others in my year. But boy, did it start me on one cool journey. I got my own weights (max dumbells were only 5kg) but I used them 3 times a week and wanted to get good arms. I wanted to prove people wrong. And it failed. I got newbie gains, but that was it. My mates had these arms at 15 lmao. It was disappointing.
Fast forward another 2 years. I entered university, and was hitting gym hard. Got my membership and was going 3 times a week. Was eating big meals at uni. Every lesson just eating food. Sandwiches, panini, nandos, everything. I had definitely lost the big belly, but partly because I had grown taller (so could just be an illusion).
I had a strong regime, and invested in this mass gainer. I went against my mum’s words, and let me tell you. Always listen to mama. She told me to chill with the scoops. Most people here have said how two scoops are grotesquely large. Well I drank straight from the blender, and two scoops with milk just touched the top of the glass. I drank it down every night. Within a month, I believe I went from 9 stone (underweight for a person at 6ft) to 10 stone. I hadn’t seen this kind of gain in… Forever. I kept going. Hit 11 stone. Then, the stomach pains kicked in. I suddenly noticed I had to go bust one every few hours, and it was disrupting my daily life. It was bad, and wasn’t calming down. I know for a fact that my ignorance killed my stomach. Also, I eat cereal almost every day for breakfast so pretty sure I’m not lactose intolerant.
Mid 2016 I stopped the shakes. My weight stayed at 11 stone. But I DID gain the fat. The majority of this weight came from muscle, but I do literally no cardio at the gym, so this caused me to gain a bigger tummy as well. My abs grew significantly, so this also contributed to the large look of my overall torso Area. It really isn’t worth doing intense ab work, as I learned, because it just doesn’t look any better. If anything, it makes you look more bloated!
Anyhoo, my doctor told me to stop the shakes as they were giving me the stomach issues. So I did, and now, I’m all good. Thank you God. Trust me, it’s not a fun experience. But. You DO get the weight and muscle you could never get.
It’s also worth mentioning that I never got any fat onto my arms, legs, etc. Just the stomach. My wrists have never grown, and I literally get depressed about how skinny they are. My arms just don’t show the hard work I put into them!!
Since stopping the shakes, I started working and ate more food than ever before. I was literally having 6 meals a day, which was major for me. But after 7 months, my weight wouldn’t go up again. I had stalled at 11 and a half stone. Then, a few weeks ago, I tried about two days worth of mass gainer. Just for old times sake. And the fact I still had half a bag left lol.
I hit 12 stone. Pretty damn epic. But the cramps returned.
Now, after seeing other reviews on Amazon, I plan to try and split my shakes up, and use this again. One scoop in the morning, one at night. I currently have a 22g grenade protein bar straight after a gym session. Then a meal afterwards (usually dinner) so then I will have my milkshake. Hopefully, I will send better gains than before and less stomach pains.
(side note that since I stopped mass gainer, I invested in Hydrowhey Platinum Protein, it is lactose free and I mix with water, and I have no stomach aches. I have also changed my gym routine and my shoulder, arms and back are looking great so far! But milk and cereal don’t give me any issues, so still not sure what the killer ingredient in serious mass is unfortunately).
I will go back to using this, and maybe attempt without milk. I’ll let you guys know how it goes.
Thanks again to anyone that listened to this. Just remember that this DOES WORK! You have to just be careful and test it carefully first. I didn’t listen and suffered the consequences. Also like others state, do some cardio to keep the belly away. You should be all good.
And to those on the body building forums that answer to hardgainers by just shouting BULK! It doesn’t work like that. We have demonic metabolism that doesn’t let us get the weight you do. I would be as big as Arnold if that was all there was to it!
So good luck to all hardgainers and I’m still with you on this journey to greatness. Thank you ON for making products that really do change people in ways you always wanted. I was skeptical and tor between either a 4 or 5 star rating. However it’s my fault (I think) that I suffered these issues with the mass gainer. It does it’s job. 5 stars.
