2nd cycle Pre-check advice and suggestions

[Alwayslearning23]

Hey guys wassup. Thanks for all the help I see that everyone gives on this site. It's good to see people always helping each other out . Going to start my 2nd cycle ever and ( 1st cycle 2 years ago I ran test Cyp 300 every week for 12 followed by HCG due to very low test levels, 429.)
Currently 27 yrs, 162lbs, 12%BF , diet is extremely on point and been training since I was 10 years old.

The cycle I will be doing is Anavar 40mg eod, test eth 300-4 and arimidex .5 eod.

Just looking to get stronger and tighten up a bit.
Feedback and yes I know I am a newbie

have you done any blood works?

Yes all came back very good. Potassium level were abit low and so was hydration levels ( which I know I work outside all day). Test levels were at 550

Have you read the beginner cycle stickys?

Yes, my blood work came back great. Slightly dehydrated and low potassium normal for me especially during the summer months . Test was mid 500s. I read all the threads .
