well, we are all different, but I don't think 1100 is high for the amount you are taking. 100mg/wk put me at 855 TT, then 125mg/wk put me at 992 TT. 300mg E10D is the equivalent to 210/wk. So, for example, if I were consistently taking 210/wk, I'd expect to be even higher than 1100 TT.
If you are looking to get to 800-900, I would definitely suggest 150mg/wk and see where that puts you. if you like injecting once per week, fine, but if you have any sensitivity to E2, split that dose in half and inject 2x/wk.
For the record, I don't think there's anything wrong with 1100 TT, as long as BP, red blood cell count, etc is kept in check. may have increased acne and oily skin compared to a lower dose, but oh well.
edit: for some reason I thought you were thinking you'd like to be 800-900 range and do 150mg/wk. I re-read and saw that you're thinking 6-800 range and 150 E10D. rather than edit my post above I'm going to leave it as-is for you to consider, but to answer your question, I think with your current dose and level, you're probably about right at 150 E10D getting you in the 6-800 range. however, my rhetorical question would be: Why be 600-800 when you could be 800-900? or for that matter, why 800-900 when you could be 1100? if doc has a number he'd like to see you at, AND you agree with him and want to aim for that number, by all means. I'd think that you and doc should be happy around 900-1000, which is probably between 150-175mg/wk for you.
