I've read some good things about a supplement called Cort-Bloc. It's that "anti-catabolic" supplement Ironmanmagazine is pushing. Is it good stuff?
Cort-Bloc is a new supplement that contains phosphatidylserine (PS) and melatonin. Both compounds have been shown in some studies to have an effect on cortisol, and it's hypothesized that these supplements may allow bodybuilders to make better gains faster, but there are no studies that directly confirm this.
A researcher named Bob Fritz is, to my knowledge, the guy who has "pioneered" the use of PS by bodybuilders. I've read everything I can get my hands on about this compound, but I'm not quite convinced it will help bodybuilders get bigger and stronger.
