Cycle Support: Tren and Test E

Just had a cycle question maybe y’all can give me your opinions/expertise.

I’m running:
1-12 Test E 250 2x/ week
1-6 Tren Ace 100 EOD
7-12 Tren E 300 2x/ week

Post cycle I have Nolva was looking at
20ED for 6 weeks or 40/40/40/20/20?

I bought HcG as well but not sure If I actually need it?

Only side effects I’ve had (currently on week 5) was maybe some sensitive nips, sleepings a mess haha.

I have Arimidex but I’m reading a lot of negative things. What’s your opinions with using and how should I use that if needed?
