Your peak could/would still be way up there. Twice weekly injections to cut the peak may help as we have discussed on here regarding setpoint for hepcidin suppression and exacerbation with age. A good hematologist would look to find root cause. Find one that has clinical experience manipulating peak/trough ratio for same AUC to lower Hct. You need to get Hct down.
325 mg/day aspirin significantly reduces RBC production for me but comes with other concerns.
If you want to continue with test cyp ... Appears you may have to (1) break up into multiple injections per week and (2) lower the weekly dose if (1) doesn't do it on its own.
Or like you said back to TU or another Test formulation.

As inferred from table above your peak and mean are much higher than the trough and leave you some room for item 2 above.
You also eat a sh*tload of iron.
