I actually really liked this protein powder! The taste is AMAZING!!! Tastes exactly like chocolate cake batter! The ingredients were a little iffy because it contains dairy which some might not like but I didn't really mind. I used this after working out and it made my body feel a lot better and less tired. Would definitely recommend

Great flavor!

This protein powder is so smooth and not chalky like others I have tried in the past. The Vanilla icecream flavor is delicious and actually reminds me of cake and it goes great in my smoothies. I love the high protein factor and this is a great all around protein .

Good Taste, Good Product!

This protein powder is one of the better ones I've tried. It has a good taste andd texture. It is a bit heavy though and calorically doesn't quite fit with my lifestyle. However, it's a good powder, very filling and worked best as a complete meal replacement instead of a sort of snack. I would buy, and would recommend.

Absolutely love this stuff

So I was a bit skeptical at first because I have tried numerous drinks like this that tasted terrible. This one tastes so yummy I actually look forward to mixing up my protein drink in the mornings! My son who is athletic also tried it and this he said never bothered his stomach like some protein drinks have done in the past. There is no weird after taste, it doesn't taste like chalk, and easy to mix!

One of my favorite protein powders

Review by Anonymous on Nov 15, 2021
As an avid exerciser, I have tried many athletic supplements and protein powders over the years. Chocolate peanut butter has always been one of my favorite protein flavors, so I was very excited to try BSN'S Chocolate Peanut Butter protein powder. The flavor comprises a balance of chocolate and peanut butter notes, and the product mixes very well in both water and skim milk. I was also pleasantly surprised at how little of an artificial "protein flavor" I noticed. Overall, I enjoyed sampling this protein powder and look forward to trying BSN's other protein products.

Great flavor

The BSN Syntha 6 Chocolate Peanut Butter powder has a great flavor. It also smells wonderful each time I open to container! The scoop itself is a larger size than I expected. Due to the size of the scoop the liquid stated on the instructions is really not enough to make it drinkable. The instructions state to add 1 scoop to 4-5oz of liquid but 4-5oz honestly is like sludge consistency. It was very hard to drink it when made as the instructions stated. I ended up adding a bit more liquid to be 7-8oz for 1 scoop. It does not change or water down the flavor at all but it allows it to be more of a drinkable consistency. Overall this is very good and tastes great. I would recommend this to others but I would highly recommend they add more liquid than the instructions state to. I received this product for free in exchange for my honest opinion.
