Has anyone tried GH-Stak and Cort-Bloc? These are pimped in the latest "Ironman" magazine and the GH-stak is VERY expensive, like $99.00. They are made by Muscle-Link, which appears to be owned by Ironman. I am always a little leary of mags that promote products like this and I've not seen any input on the boards on these specific products. It appears to be a growth hormone releasing peptide compound.

Any input would be appreciated.
