RE: T3 in low doses doesnt cause CATOBOLISM!
Where did you read this?
Experience from past users indicates this not to be the case and will also require anabolics to offset losses. You have to remember that users of T3 are in a cutting situation which is catabolic in itself.
However, eating excessive amounts of protein will help minimise catabolism, perhaps to the point of nil if one was to eat enough. Regardless, whats the point in that? 'Excessive amounts' means excessive calories, which is totally counter-productive to the idea of having a cutting diet!
