Good post Jos!
First, HCG will increase intra-testicular E2 especially if you inject alot in a short time period and it's very difficult to manage with an AI. This is why you should be injecting low doses more frequently. 700 iu in two days is a bit much so you could be sensitive to HCG OR had a baseline E2 level that was pushed over the edge with the addition of the HCG.
I would think it's more the later then the former.
I would do two things:
1. Stay on the AI; you need this anyway. BTW, it's ideal if you can take the AI in smaller doses more frequently as well. Take it at the same time you inject your HCG below.
2. Spread out your HCG injections to E3D with 225 iu per injection. This provides the same amount of HCG but does not "bang" the boys hard - like 700 iu in 2 days - and provides for a more natural and consistent level of HCG.
Much has been written on this so do some research and see what the other guys have to say here. BUT will say this; you need HCG and the fact that the clinic has prescribed it for you along with an AI means they know what they are doing. So, discuss my suggestion with them if you'd like and see what they say but it sounds like you're in good hands.
You may also want to get a new E2 sensitivity assay as well just to see where you are at as it will tell you much.
And hey, welcome to the community
