I got my cholesterol bloodwork while on a hefty dose of aromasin.
Test was at 1500 ng/dl and e2 was 15 pg/ml (too low).
Total cholesterol was mid range. Hdl was towards the lower and ldl was towards the upper end, but they were still in range.
AFAIK ai's do not directly lower hdl, they do that indirectly by lowering e2 which stimulates production of hdl.
