By injecting weekly your E2 levels are probably dropping towards the end of the week and are higher in the first half of the week. If you want higher E2, split you dosage up twice weekly or just increase your dosage.
If you choose the former you might need to increase your dosage a little because injecting with greater frequency can decrease E2. You probably would do very well with estrogen on the higher end and might actually be able to handle E2 levels even higher.
My understanding was the more frequently you inject, the less testosterone is converted into E hence why I was pushing it to E5D. This is obviously not the case
I inject EOD to keep my E down. I am very similar to you in that I have low E Which is why I started Trt but 120mg a week keeps my e at a perfect level. sometimes however it creeps up if I drink. I donāt like an AI so I inject more frequently
