  • 10 Chocolate Milkshake

I really love BSN Syntha-6! It's both effective and delicious for me! It's quite affordable too (esp the 10lbs pack). What I like the most about it is that it has THE BEST flavor in all Protein Supplements I've tried (a lot of them). I especially love their Chocolate Milkshake flavor, tastes almost like real chocolate (I highly recommend blending it with other ingredients such as milk, fruits, oats, etc to make it super tasty!). It does have a higher sugar content compared to other Whey products; but I think is alright, some of it is Fiber. I primarily use BSN Syntha-6 as an ingredient for my homemade baked goods: High-Protein Brownies! My primary snack item. Good job BSN!

I have recently switched over from ON whey to Syntha-6 and I have to say I love it! This mixes insanely easy and it also taste great. I had my doubts about the Cinnamon Bun, but it tastes fantastic. I have been having some great workouts recently and I have not been as sore as I normally would be. I would recommend this product to anyone.

Syntha-6 is not Syntha-6 Edge. Syntha-6 is a solid protein blend to build muscle mass. I use it in the morning with my oats, during the day as a meal replacement (if needed), post-workout and in the night before bedtime. The "New York Vanilla Cheesecake"-flavour does not taste like the Starbucks cake (nor do I know about the real New York cake), it is more like an easy taste of sweet vanilla. Not creamy, not too sweet but like vanilla. "Strawberry swirl" taste like a sweet strawberry milkshake from the restaurant with the large "M". I drink my shakes with water!

Flavor is awful. Tastes like a candle. I love all other flavors and am very disappointed with this one.
