Well I assume yes but during training you're not worried about controlling insulin. You spike insulin in the PWO Shake to help keep the body from being more catabolic from that workout. You're wanting to control insulin during the ULC part of the day more.
Yeah I know the spike wouldn't matter during training, If anything I guess it would be beneficial. I'm just curious as to how it works and if it does spike insulin levels or not. Maybe the excess glucose just goes straight to liver glycogen since the liver converts the lactate.
