it’s really important to have your blood tests done right in the middle of your dosage schedule.
id argue its more important to have blood testing done at the very end of the schedule when levels are lowest, but both values are useful to have. even if your peak is a little high, if your trough is too low you should up your dose anyway (though this is unlikely to be the case unless youre taking EV). plus if your peak is a high but your T level is too high and youre doing mono youll want to up your dose anyway. its nice to have but not nearly as valuable as trough levels in managing your dosage.
E level is higher than it needs to be so dosage should probably be lowered, but the "maintenance dose" terminology is still a red flag imo. just make sure they are dosing you reasonably lower and your levels are within range. also if you arent getting your T levels tested as well then you should do that (just saying this because it was absent from this post)
