But did Chris Mosier go through puberty with female hormones? If not, then this really isn't comparing the same thing. Jillian had the advantages in development (advantages for cycling) of maleness until she was past 30. Those advantages shaping body shape and numerous other factors are *not* erased by hormone therapy. And, we also know that the allowed T levels are more than 3 times the normal range for females....that too provides a huge advantage.
