  • 9 Strawberry Milkshake
  • 8 Chocolate Milkshake

I go to the gym 5 days a week and take this before/after gym. I started out at 115lbs and now I'm at 130lbs after about 4 months. 15lbs of muscle gain and I'm going to continue it for another 8 months and see how it goes. 1 year full The strawberry mixes very well and leaves no crumbs at the bottle of the cup Chocolate does not mix well at all. Leaves crumbs all over the cup including the sides and thats after really mixing with a spoon and shaking.

  • 10 Banana
  • 8 Cinnamon Bun - Exclusive!

Banana is the best protein flavor I think I have ever tried. Reminds me of Banana Nestle Quik from when I was a kid. Cinnamon Bun is good as well, but not my favorite. I definitely will be ordering more of the banana flavor.

You want a protein that tastes good so that you stay consistent, and after trying several brands and flavors, this chocolate milkshake has me hooked. Excellent protein and great price. Almost always buy one get one half off.

  • 10 Vanilla Ice Cream
  • 8 Cinnamon Bun - Exclusive!

Tried the cinnamon and vanilla ice cream so far. I've tried about 7 or 8 different brands of protein over the years and this stuff mixes the best out of all of them! Vanilla is weak but that's not a bad thing. 2 scoops in a blender bottle and it isn't crazy thick or overpowering. The cinnamon is a strong flavor but in a good way. Should be good for baking with.

  • 9 Salted Caramel
  • 8 Vanilla Ice Cream

Such a good protein, mixed easily and is smooth, and doesn't have that whey protein taste. Vanilla had a bit of the proteiny after taste but salted caramel has a subtle flavor in a good way, I like it best mixed with plant milk.

Loved the protein, mixed well, with good flavors. Just what I would expect from BSN products. Vanilla was very good, strawberry milkshake was a little overpowering, but I liked it

German Coldstone - For what was supposed to taste “like ice cream” it fell short in decadence. The accuracy of flavor was there, and BSN protein is great overall, so that’s where it gets an 8. Birthday Coldstone - I expected way too much from this, despite the bad reviews I read. Again, BSN tastes great, so there’s the 6. But this is LITERALLY vanilla protein with sprinkles. Strawberry - Quite literally my favorite so far. I would argue that it really tastes like a milkshake for a protein powder. Smooth, creamy and delicious. Cookies - This just got too hyped up to me from other people, so I was expecting a lot, and got less than I expected. Again, smooth powder, good flavor, but basically vanilla powder with questionable cookie crumbles. I love BSN OVERALL, so I’m mostly just giving an honest individual review of each of these, but overall they win for me over other powders, for price, consistency, and flavor. Looking forward to trying more flavors 👍🏻I DO wish there were more options in the 5 lb since that’s where the sales prices usually are.

  • 8 Chocolate Cake Batter
  • 10 Chocolate Peanut Butter

I love the chocolate peanut butter. It mixes great with water and it makes me want to drink protein which is something I struggle to do. The chocolate cake batter is good but it needs to be mixed with milk. Overall, great product for a great price.
