Honestly it’s actually delicious with oat milk. Water, tastes ok. 4 stars because it doesn’t mix great in oat milk. Mixes great in water though.*

Protein content is great per serving size but the flavor disappointed. I’ve had awesome flavors from this company before so I had high expectations. Serious dud in flavor. You can tell it’s orange dreamcicle but you have to use your imagination.  I excepted a solid full flavor and it’s really dull and disappointing.  I will buy this isolate from this company again but not this flavor *

I first used IsoFlex back in 2012 and while it isn’t the only isolate I’ve ever used, it’s one of my favorites. Allmax is a trusty brand, and the peanut butter and chocolate flavor is great. Mixes easy, digests easy, and has great macros too. Love it. *
