HCG does not require a pituitary gland to do it’s job
The difference is neither work very well, clomid mostly has lots of side effects, HCG stimulates only half of the testicles and doesn’t work very well most of the time, the latter is a hormone your body evolve to handle and will work.
TRT works better.
I started at 140mg 40mg eod. Labs and consult 3 months out unless you want an earlier one
