This is what I found - it's supposed to mimic the ratios of GU:

Home-brew power goop:

7 and 1/3 Tablespoons of Honey
3/4 teaspoons of Blackstrap Molasses
1/10 teaspoons (just shy of 1/8 tsp) of table salt

Be sure to mix everything together well, and it should make enough to fill a 5 serving GU flask.
