✅ Pros: -Subtle and delicious peanut butter cookie flavor (adjust water amount!) -Easy to digest and gentle on the stomach -Seems effective for protein supplementation ❌ Cons: -Wish the flavor was a bit stronger Pro Tip: I add about 5g of erythritol per serving, and it makes it absolutely delicious! Honestly, the peanut butter cookie scent was a bit weaker than I expected at first, which was a little disappointing. However, when I mixed it with less water than usual, the flavor became much richer and it tasted amazing! Most importantly, I love how easily it digests. Other protein powders sometimes make me feel bloated, but this one doesn't cause any discomfort at all, making it great for consistent consumption.

Best protein

Syntha-6 is the best protein I have ever tried. Great taste, smooth texture, and it mixes really well. I really enjoy using it and will definitely keep buying it.

Tastes great!

I add a banana for a really delicious shake. I usually have shake at lunch, most often on the days that I go to the gym.

Great tasting protein!

Not sure why the bad reviews on taste, as the PB variety is new, tastes great, and a great alternative to the existing flavours! The ingredients are great, it mixes up very well with fruit to make smoothies (esp banana), and perfect to take after a workout. Love the Syntha isolate and wish they'd come out with more flavours as they're all great!

didn't like the texture, has a texture that is kind of sandy.... like it was a vegan protein
