Opinion on Gyno Symptoms

Looking for opinion:
Taking 210 mg Test Enth/week with 500 iu hcg 2x/week and started experiencing some nipple sensitivity. Immediately started on daily dosage of 0.5 mg arimidex for 1week. now taking every other day as maintenance.

I “THINK” the symptoms have subsided, but now I am paranoid that there might be a “little sensitivity” left.That and my nipples are often hard (now I do keep my house at 70 degree’s).

The question is - do you think the dosage/frequency of arimdex is reasonable. Should I stop worrying? I dont want to go over board with the anti-e, but at the same time really hate the prospect of gyno!

Thanks.
