Move closer to 1:1 than 2:1. You’ll go faster and feel better.
Start here: How are people getting 100g+ carbs in a bottle? - #198 by Dr_Alex_Harrison, then scroll down to read the rest of the thread for more related info.
I’m also interested if @Kovacic did an analysis or if Skratch published somewhere that they use a 2:1 ratio.
You can safely do away with at least 80% of the below (probably 100%) and reduce osmolarity a bit further, leaving performance unchanged.
