Anavar and all AAS promote muscle growth, and if in a caloric deficit slow muscle loss.
If it is me, I would cut while on TRT only, lose the weight even if some is muscle. Then after the cut use the Var to regain the lost muscle quickly. Muscle memory is legit IMO.
I figure that I am at the tail end of blasting, honestly not really the most fantastic idea at my age. So I want to make the PED use (which was really moderate TBH) over the past two years count for something - and I am paranoid about losing too much muscle.
I thought that the addition of anavar would make a nice cushion to give me more wiggle room for losing the fat while ensuring that I keep my gainZ.
