They're legal in cali. I always use private md labs, and get the female hormone panel with added sensitive e2. You can get lc/ms through priavte md labs you just have to pick the right test.
edit: it may have changed recently but last time I did bloodwork last year it was legal. I haven't done blodwork this year because I haven't even ran gear fir more than 5 weeks due to personal issues arising. I haven't even used my trt dose most of the year.
