heres 3 sites to choose from if you need to get your estradiol tested before any of your doctors can write you a referral...i dont think either one requires an RX for the labwork of your choosing (imagine that...having your bloodwork tested
WHEN T F YOU want and
WHAT T F YOU want)
12% body fat i would and most would consider quite fit...i can see you at 6' 4" wanting to carry a few more pounds of muscle on being only 190...
only you know yourself if your lack of motivation is mental or physical or laziness...
see if you can get yer as$ in the gym and lift some heavy a$s weights for a month consistent...you will know if you are in need of medical help if you give 100% and see zero results
wish u the best
