Are you talking about protein powder? I tried about everything and they all tasted bad to me unless I mixed them with stuff then they had way to many calories.
The best I’ve found so far is just plain pea protein and I just mix it in water and chug it. Tastes like chalky dusty water. Not much flavor. It makes anything other than water taste like shit though, and it doesn’t taste good in water either. It just kinda taste like dusty water.
