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.

  • 10 Candy Cane - Limited Edition
  • 7 Pumpkin Pie - Limited Edition

For my shakes, I mix 2 scoops of this whey with one scoop of muscle milk chocolate gainer in chocolate milk. The candy cane flavor tastes just like mint chocolate chip ice cream with this mixture, which I absolutely love. As for the pumpkin pie, there is a little more pumpkin spice flavor than I am used to from pie. It tastes really good though, but after a while of using this flavor it gets to be a it much. I would definitely buy the candy cane flavor again! I'm actually probably going to right now.

BSN has some of the best tasting protein I've ever had. I've only had two flavors but both were great. I mix with almond milk.

  • 10 Salted Caramel

Chocolate Cake Batter is delicious. Salted Caramel goes great with coffee, but isn't great on its own. As for the protein itself, I like it. It's not making me superhuman overnight, but it's good protein. Any protein claiming to change your life on its own is lying to you. I'm almost 30 and I'm still getting stronger, so it's doing its job.
