interesting.. the way I look at it, it takes less AAS to build muscle than to keep it - the reason being food is so anabolic in huge doses and when you're starving yourself (cutting) the body is gonna strip away non-essential tissues first.
Last time I cut I ran a very light 75mg ED of tren only, held some muscle and got very lean but I think I would have held a lot more on double that. First time I cut I went natural, right after a cycle, and after the first 4 weeks I started losing size bigtime despite no intense cardio and lots of protien
