tried it 3 days ago,took letro the day before, 70g with 500ml of water, then a big bowl of pasta and other carbs for carbing up a bit, zero water, 1:30-2 hours later I was looking sick! but being dehydrated sucks lol all i was thinking about was to drink something...
gonna give it a try soon for hyper hydration before a workout! from what ive read its best to consume the glycerin 2 to6 hours before the workout, with 500ml of water and also 500ml every hour after... is that how you do it?
