On this site, you’ll find most people recomending Surge as the optimal PWO drink. Coincidently, you can buy it here too. =P
There’s a lot of very thorough explanation of why Surge is considered optimal throughout this site. Look under the Authors section for John Berardi and browse through his articles or listen to the audio interview with him. In the audio interview he also describes low fat chocolate milk as being an ‘okay’ alternative.
If you can get your parents to go for it , then Surge is probably your best bet.
In her “Hard Body Training” article Christine Lamy talks about using a mix of protien powder and pineapple juice pwo.
I don’t know where this would rank in terms of effectiveness compared to Surge, or the LF Choc. Milk, but it got me thinking about this low-budget snack my grandmother used to make when I was little. She’d take a can of crushed pineapple and mix it with a packet of powdered hot chocolate. Then she’d spread the resulting paste on a sheet of plastic wrap, fold up the plastic wrap and stick it in the freezer. After a couple of hours you’ve got a bar that looks kind of gross but, if memory serves, was fairly yummy.
It’s been a long time since I’ve had one of those, but I’ve been wondering if substituting some protein powder for the hot chocolate packet would result in a decent post workout snack.
