I’ve been using this mass gainer stack for about a month now, and it’s been solid for my bulking phase. The Serious Mass in Chocolate flavor mixes well without too much clumping, and I love that it’s not overly sweet. The creatine powder is easy to measure and dissolves quickly in water. While the price is a bit steep, the quality of ingredients justifies it. Definitely helps me hit my daily calorie and protein targets. Not sure what ‘trump green card’ has to do with this, but hey, building muscle is a win!
