Recently I started using Gookinaid (gookinaid.com) pre and post workout. Holy shit! This is the best supplement for the money hands down! I ket a kilo for 10 bucks at a local running store. Makes like 2 months worth. No artifical sweetners, colors or anyting. Just electrolytes, glucose and a hair of fructose.

Seriously my workouts have blown up the last week using this stuff. I always drank a ton of water, but I've learned that you can actually dehyrdarte yourself by drinking too much water (it upsets your salt and ion balance). I also but some in my protien shakes post excercise as glucose faciliates glycogen push back into muscles.

Honestly, I put this shit up there with protein powder and multi vitamins. Sooo much better than gatoraid, pedialyte, accelaid etc...

PS I forgot to mention it works great for avoiding hangerovers (personal testimony from last saturday)
