t-dawg or anabolic diet?

Which on is better at gaining mass and losing fat?

Not sure what you mean. I personnally have never heard of ither one. Can you give a few more details about each particular diet?

i believe he's talking about a few diets from testosterone.com, it's an online magazine i've stumbled across a time or two

The T _ dawg diet is a form of low carb. dieting. Ive read it online at their site as well. I have heard mixed reviews on both of them, but a few have gained some good muscle and lost fat while on the T -Dawg. Worked fairly well for them, just be prepared to be very lethargic and tired.
