I get 200 a week from my doc, which can either give me 1500+ if I inject it all in one day then test after, or if I split it into 3 x weekly shots it keeps me at 800-1000 all the time (instead of peaks and crashes from standard inject protocols)
E2 is fine at this dose, my prostate measured to the bottom end of normal back in March so it's all good.
I do subs sometimes but that huge thread about it on that other board with actual blood work results had me reconsider
