So a few months ago, my wife glomed on to some protein shake and has been drinking it every day since. I found they made a powder and told her "yea I can make this cheaper just using the powder." She bought in, and slowly I started swapping it with straight up Serious Mass weight gain powder and heavy cream. I created a recipe that mimics one of her favorite Starbucks drinks, and she just sucks it down. I do 400ml of heavy cream a half scoop of that Serious Mass 1tbsp of espresso powder and 4-5 tbsp of chocolate syrup I'm about to start mixing appetite enhancers into it too. I got some Feast Mode pills and the flavor is kinda mild, so I think the rest of the drink will mask it. The shake is just shy of 2000 calories per drink, and at her height/weight, she's getting almost all the calories she needs for the day before she even gets to the office. She has been in a plateau for over a year, but now I can clearly see the results. She's chesty, but now her belly goes past her boobs, and she has a certified fupa now. She was right at 200 when we started dating, and she's over 320 now. When we were still dating, she worried about how much weight she was gaining as she had put on 40lbs in a year. One night, we were in a drive-through at one of her favorite places right next to my house and she placed a huge order. I asked her, "well, you say you are worried, but that's a big order, what are you gonna do after you move in with me and you can eat this all the time?" Her answer: "get fatter."
