I use a product called Nitromax by Sandco International. The only way I find this stuff is through their web site:
http://www.sandcosports.com/nitromax.jeo?refid=14
The web site is horrible, their products are horrible, and everything they sell "works better than steroids", BUT their Nitromax post workout drink is awesome. I get 25lbs for $167 and it lasts almost a year.
1 scoop:
40g glucose/dextrose
26g whey protein
1g fat
plenty of aminos and vitamins
and silly stuff like MCTs and Nitrogen, which is this product's claim to fame, thusly NITROmax.
1 hour later: (blended)
1/2 c cottage cheese, 1 c skim milk, 1 tsp PB, 1 MRP, 1 c water
This drink is consumed slowly over a period of about an hour... mostly because it's thick and filling, and drinking it fast gives me ass-erruptions.
