Great you could be the one who stays in the game you winon the difference between those who succeed the ones who make it smartest talented luckiest they are the ones who simply quit Think about all the times something with passion and energy maybe it was a new habit a new goal or a new opportunity at first you were excited motivation you had a vision of where you wanted to be but reality hit things got tough progress Felt slow you started you looked around and saw others moving faster than you that voice in your head whispered this isn't for you you gave up the cycle repeated itself over and over again

best strawberry flavored protein powder

Great taste! I have been using chocolate for a couple years and got the strawberry for my wife. Kinda tastes like luckycharms and a hint of the a dairy queen vanilla-cone. obviously tastes like strawberry, I'm just mentioning the slight background flavors and they dont bother me. One thing I have always appreciated about serious mass is how well it mixes using hot water from my sink and aggressive shaking. Fill your bottle like, 1/3 the way, then a serving of serious mass, shake the crap out of it, top off with more hot water and shake again and its good. For some reason the strawberry mixes better than chocolate.

Best one on the market by far

Closest to chocolate milkshake you'll get. Suggestion. Let it sit in the fridge after you mix it, let it sit about 10 minutes for it to settle cause it's bubbly otherwise, plus it helps settle any clumps that might still be there. (I've used a shaker, ninja blender and a portable blender they all still leave small clumps so trust me on this) if you're looking for extra calories for weight gain specifically, I suggest adding 2 scoops of vanilla bean ice cream plus a bottle of water and then the 2 scoops of the mass gainer. In 3 days I noticed getting plumper. I I think I have a low key eating disorder so take my advise when I tell you this stuff works to gain weight. When you can't eat when you are stressed when you just can't do anything, at least drink this cause it goes down easy, it's not too thick, it's perfect and again if you add the ice cream it's like you're drinking a thin chocolate shake. I had to buy the big bag cause this stuff works so well. I haven't tried with yogurt but ice cream faaashow. Don't waste time with the other crap other companies sell cause they don't taste this good. I got one more expensive and it was chocolate flavored and tasted like trash and made me sick. I hate everything but somehow I loved this. So go with it. From one picky grossly skinny person to the next. Said with love cause we all gotta laugh about ourselves.
