Tbol isn't really a "cutting" AAS, although I'd argue few are(MAYBE tren and var). I digress, anyway, the reason AAS helps with dieting/cutting is that it helps your body not go into a catabolic state. The muscle sparing effects of AAS are what make it great for dieting. That being said...the dieting is left to you. There is no AAS that is gonna make the fat just fall off, only the treadmill! So get at it! Hahah
