    This product is for…

    Endurance athletes doing long efforts (100Ks, long runs, racing) who need high-carb fueling and a stomach-friendly gel. Works well for those who prefer neutral or low-sweetness flavors and want something easy to get down in volume.

    Worth noting…

    The Nootropics Beta variant has a yellow stripe and contains 200mg caffeine — easy to confuse with the standard version. Can be emptied into soft flasks for easier consumption on the go; no caffeine in the standard gel.
