You can save TONS of money if you're a frequent user by just buying $60 worth of bulk maltodextrin from Honeygrain online. 50 pounds, shipped, enough to last 2-3 years for a regular user. In comparison, you'll only get 4-5 pounds for $50 for most sports drinks.

The main active ingredient in Cytomax and most other endurance drinks is maltodextrin. It's like 90%+ of the calories. Nearly all sports gels are made of maltodextrin. Do a search on this forum - lots of stuff on it.

I go through about 4 pounds per month of maltodextrin for long rides and long runs. It works great.
