Yes, there will be less of an emotional rebound when test is used, as long as the AI used on cycle didn't destroy all estrogen. My reasoning being that when you run a non-aromatizing cycle, you end up with zero test and zero estrogen (or close to it) while on. Your androgen recepors don't get hypersensitized due to the fact they are being occupied/used while on, but your estrogen ones do, all over your body they are primed and ready, so when you start pct, and start natural test up again, and some aromatizes (which is good, estrogen helps joints and lipids), the small amount acts as a lot more fora while until things rebalance.
this is one of the reasons I try and incorporate a test base into any cycle I run.
