This weekend I set out with my first homemade trail carb drink, modeled after Hammer Perpetuem powder. I calculate 80 kcal/mile needed.
Yield: 1 LB, good for 25 miles.
Maltodextrin 11 oz (honeyvillegrain.com)
Whey Protein 4 oz (GNC)
Soy Lecithin 1 oz (local health food store)
Chromium Picolinate 200 3.5 tabs (700 mcg, GNC)
Choline Bitartrate 250 1.5 tabs (375 mg, GNC)
Acetyl-L-Carnitine 500 1.0 tabs (500 mg, GNC)
Total cost is $4.68/LB compared to $9.40/LB for Perpetuem.
The malto was a 50 LB bag (about 12 gallons)
The flavoring comes with the Whey Protein of which I have 10 LBs lying around.
Bulk soy protein (44 LB bag) would drop the price to $2.82/LB + flavoring.
