300mg Test E Weekly ( Sides )

Long story short. Got my labs back and they are not good. Still feeling quite shit energy / motivation / training wise. Sexlife and erections seem ok so far.
Hemoglobin 174 g/l Not Normal 134-170 g/l
Hemocrit 52.1 % Not Normal 40.0-49.0 %
Erythrocytes 5.90 E12/L Not Normal 4.50-5.70 E12/L
Cholesterol ok
Testosterone 54.1 nmol/l Not Normal 8.0-30.0 nmol/l
SHBG 21 nmol/l Normal 14-71 nmol/l
Free androgen index 257.5 % Not Normal 20.0-81.0 %
Prolactin 688 mIU/l Not Normal 73-407 mIU/l
E2 310.0 pmol/l Not Normal <161.0 pmol/l

As it seems, for me P5P does not work as good as for others ( 50mg ). I guess if we speak about " trt " then also 100mg weekly is for me too much, because E2 is quite high and with that rises also prolactin. Some time has passed and Hemoglobin and hemocrit have come down to 173-174 / 52% and stay there.
I gave it a tought, and i think i should try PCT and see where it gets me . I kinda want to know what feeling it is to go trough PCT, maybe it is better for me cruise/trt vs pct.

My question is, when im on 100mg and hcg, if E2 goes out of whack, is it OK to take armidex ?
Also when it is time for part2, is it ok to take armidex, if there are bad sides ?
