I am currently using 100mg/day test cyp for lifetime HRT d/t low endogenous test production.

I want to try a higher test cycle. I want to Prevent gyno.

I am 6'4"
246 lb.
15% body fat
33 years old

here is the sample cycle that I am planning on doing:

Weeks 1-10 Test enan or cyp 500mg/wk (250mg twice a week)
Weeks 11-next cycle Test enan or cyp 100mg/wk
Weeks 1-12 Liquidex 0.25 mg/day
Weeks 1-12 Nolvadex 10mg/day

PCT (only to prevent estrogen rebound/gyno, not needed to increase endogenous test production.)
Weeks 13-17 Liquidex 0.25mg/day
Weeks 13-17 Nolvadex 20mg/day

My questions about the cycle are:

Is this too much estrogen blocking to prevent good gains?

Is it necessary to do the PCT since I'm on HRT to prevent estrogen rebound/ side effects?

Are the liquidex and nolvadex doses good both in cycle and post cycle?

Thanks in advance for any advice.
