This week we have our first tandem episode in, well, forever. Last summer Skratch Labs released a new product, Superfuel, that is a high-calorie drink for endurance athletes. It's a drink mix built on a fundamentally different philosophy from their super-popular drink mix known for it's blend of sugar and electrolytes. Lim has long been an outspoken detractor of drinks that use maltodextrin as their fuel source, so the introduction of Superfuel was a big surprise to me, and frankly I wanted to hear from him why the change in philosophy.
