Many ideas for taste have been scrapped. It is most likely impossible to have sufficient NaHCO3 and not have an unpleasant taste and texture. As a result, I will have two separate drinks: a baking soda in water drink and the H2O2 and electrolytes in a separate drink.
I found a recipe for an electrolyte drink, so the Gatorade packet will no longer be needed. The future performance drink will be entirely homemade and easy for everyone to make on their own.
