Will not buy anything else! ### ⭐⭐⭐⭐⭐ STRUGGLE TO EAT *by on Reviewed in the United Kingdom 30 October 2025* I don’t use this protein for the gym I use it cos I struggle to eat normal food and so this sometimes becomes my only source of food and with 1250 calories per shake I know if I drink 2 a day I’ll get all the nutrients I need infact probably more then I’d get from everyday food, I’ve tried loads of different powders and this is by far the best one for taste , filling me up and keeps me looking well, ITS WELL WORTH THE MONEY IF LIKE ME YOU STRUGGLE TO EAT!!!? ### ⭐⭐⭐⭐⭐ The best after trying multiple mass gainers over the years *by on Reviewed in the United Kingdom 23 March 2026* Is my fav mass gainer. 1 thing though lol does come out the same colour it goes in when you urinate haha almost like chemical waste😂😭 but I love it all the same. Also read on for mixing tips if you need/wantI take half the serving size (to save money and its an addition to my diet not a main meal). So 180-200g with 250ml of milk or 200ml of water for a thick shake. If you go to 300ml it will be more watery regardless of the 200g of powder. So for thick 200ml water/250ml milk. For more runnier shake 300ml water or milk. Also peanut butter/ice will help thicken your shake.
