Have you read the other posts on SC/SQ injections?
You cannot take Arimidex E5D as the half life will drive E2 low then allow it to get too high; which might not feel right. The the lab results are a function of lab timing and are not useful for dose refinement. Have you read the stickies? E2 levels can affect mood, energy and libido.
hCG also does not have a half life that supports what you are suggesting. It is best dosed EOD.
You are not going to have adverse reactions, certainly not optimal.
With 140 mg test e I would expect that you will need 1.5mg Arimidex per week if you are a normal anstrozole responder. You need to understand the implications of being an anastrozole over-responder. You should try to take your Arimidex EOD. This can lead to problems when dosing pieces of pills.
Do you have lab results for TT, FT and E2?
