I was put on TRT about 3 months ago. My test level was in the 100s and my estro was in the single digits. So I was prescribed 50mg of Test C twice a week. That brought my test up to about 650 and my estro to 13 (still a little low it seems). These labs were done 36hrs after injection. I decided to do a blast. I'm doing 450mg of Test E/week. I have pharma aromasin on hand. I'm about to start my second week of the blast which I know is usually when you start the AI. I'm kind of scared to take the AI because of the low estro feels. What should I do?
