Optimum Nutrition Serious Mass Protein Powder High Calorie Mass Gainer with Vitamins, Creatine and Glutamine, Vanilla, 8 Servings, 2.73 kg, Packaging May Vary

This is soo good and tastes so delicious. Love the chocolate flavour I use it with oat milk and a little bit of water and crushed ice. Tastes like a milkshake. Sometimes I add a whole banana and peanut butter to pack in more calories. I can imagine if you drink cows milk you’d pack the weight on rapid. I have put on a stone using this but that was over a space of 6 or 7 months and I was drinking two a day but I’ve cut down to one or forget not good so I’ve had to go back to 1 a day then I’ll be back on 2. You can easily put pounds and stones on with this protein shake. You just have to be consistent really, along with eating. Consume more calories than you need (I’m 9.10st) trying to get to 11 tbh. I was eating pure beef burgers and just lean meat, bread and peanut butter along with any foods high in calorie that pack pounds on, that helped with the weight gain. Be consistent and you’ll get results. Lost count of how many I’ve brought tbh.

I’ve used this product on and off over several years. It really is good not full of garbage like you can find in other products of a similar nature. It’s a very well trusted brand vanilla or banana is my favorite as they both taste really good. You can probably use half of the recommended serving each time and still get great results. Just stick to a really good eating plan and you’ll feel the benefits of this.

Serious Mass is perfect for anyone trying to put on healthy weight and size. It mixes well, tastes great, and gives a big boost in calories without feeling heavy. I noticed improved energy, faster recovery, and steady weight gain within weeks. Definitely a reliable mass gainer!

This was my second purchase of the Serious Mass Protein Powder. I did not buy it for training or body building sport. I developed a temporary condition that made me inactive for a couple of months. During this time I was not eating properly or getting any exercise. I dropped from my normal and average muscular 12 stone frame to 10.5 stone in weight. I looked at reviews on products for putting on weight and the feedback on this product was really good. My own experience is that it worked for me and in only two purchases over two months I regained my weight. It was very good value for money for my situation. The taste was more bland than a fruit juice but not unpleasant in any way. I used a hand blender to mix it and this made it smooth without any dry lumps. I recommend it for putting on weight. I was able to double my eating calorie intake each day. As for body building sports, I cannot feedback on that since I think it would take a bit longer to assess.

protein good quality, valuable, seal pack, mixability,

I never expected this to be so huge. Even the spoon is too huge 😭. Tastes great I take it with water. Just got now. Bought it during black Friday sale. Best decision

Did not fill any different

I mix mine with milk and some times with ice cream as well, it is really good. I've tried them all in the past, strawberry is the best tasting and dissolves the best. It is really sweet though. I don't know what people are complaining about, the scoop is half the diameter of the lid.
