Lowest Carb Protein Powder

Does anyone know what the lowest carb protein poweder is on the market? if so how is the taste?

Zero Carb Isopure

Good, not great, but not horrible

There are others, but that is the one I have used most often in the past

What does it matter how low carb it is? Metabolic Drive is low enough.

Are you on Atkins or something?
