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.

Good

On my 7th or 8th bottle probably, this is the real deal if you're trying to put on weight. The milk chocolate is my go to, but all the ones I've tried were actually pretty good taste wise. it's one of the few powders that Id say taste like what it says it is, like my favorite is milk chocolate, and it actually taste like a chocolate shake when I make it.
