Yeah, supposedly the T-Mag version was quite good. Of course, I think it's offline now that T-Mag has descended into some kind of online store. Anyway, I still think there are better bulking diets out there. I personally a slower increase in muscle mass with minimal fat gain as opposed to as much LBM as possible. Another problem I see with ABCDE is that hormonal balance changes much quicker than the cycles do. 2 weeks at calories restriction will put you in hormonal hell, and will probably cause novices to jump into the bulking phase sooner. I think with strict calorie control throughout the diet, it would be effective, but I'd be extremely weary of attempting at low body fat levels when your body is bending over backwards to put on fat. Lots of good things have been said about the training/nutritional info at http://www.hypertrophy-specific.com.
Yeah, they make supplements, but all they make is protein powders and creatine. I doubt you'll find a body builder or nutrition expert in the country that will deny the effectiveness of those two supps. Except liquid creatine, that stuff is crap. Edit: Link was misspelled.
