BikeRadar score3.5/5Find prices on Bicycle Blue Book

PSP22 gets its carbs from maltodextrin, which is particularly easy on the stomach so it shouldn’t pose too many problems if your digestion is on the delicate side.

The original flavour contains just the maltodextrin, with no flavours or additives, and a more expensive organic fruit punch version is also available. Sachets provide convenient refills when on the move.

No electrolytes are included but its companion product SIS GO is isotonic. The orange, lemon and blackcurrant flavours all contain the sickly chemical sweetener aspartame.

Freelance Writer, UK
Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
