I've heard the same old story, if you don't include carbs in your diet you can't grow muscle. I call "bullshit"...
My last cycle was done on a near "Atkins" diet of almost no carbs at all along with massive amounts of protein in the form of meat, seafood, & eggs. And I gained 15 fat free bloat free pounds. 12 of which I kept after the cycle was over. Maybe being a lean hard gainer makes a difference, but all I know is that it works for me.
I'd be really interested in hearing the results from others that have "actually tried" a low carb or no carb diet during a cycle. Because it seems that most people trumpeting the absolute need for carbs are the one's that have never tried it.
