I've asked this question in other places, but rather than hijack other threads, I thought I should post a new thread. I've been on testosterone replacement therapy (TRT) since December 29th. I started with 200 of T-cyp per week and then went to 100 E3.5D. I was taking 500 of Human Chorionic Gonadotropin (HCG) every three days as well. No Aromatase inhibitor (AI). My T levels went from 49 to 1041 on that protocol, but my E levels went to 80 on a normal scale of 5-40. Just last week I changed to 150 E5D of T-cyp, 500 units of Human Chorionic Gonadotropin (HCG) two days prior and .5 mg of an Aromatase inhibitor (AI) on the day of my T injection. I'm not feeling any better, so I'm wondering if I can jump my Aromatase inhibitor (AI) to .5 mg EOD? I'm 6'3, 280 lbs and 26.67% BF. Guys have ranged from .25 mg of an Aromatase inhibitor (AI) E3D up to 6 mg ED. I'm not going to wait for blood tests every time I change my Aromatase inhibitor (AI) dosage.
