Some people have the genetics to get really lean on cycle while eating above maintenance. Tren usally aids this ability.
Some people dont have that ability, regarless of the amount of AAS.
This also depends on how lean you already are, how lean you naturally are, how long youve been dieting, how goodd your diet is.
Basically, who the hell knows. But if youre using tren I assume its not your first cycle. So you should have some idea of how your body reacts. Use this knowledge to decide what kind of nutritional approach to employ during your cycle. If you dont know this sort of thing about your body you should find out asap, so you dont keep running cycles whilst taking shots in the dark.
