I think 500iu HCG e2d is just too little to recover fertility.
I’m not a doctor, just sharing my own experience.
HCG will force your tests to produce testosterone, but will shutdown your own HTPA, then you have Clomid signing to Gnrh to produce LH and FSH (testosterone and sperm) but then comes testosterone cyp and HCG and says you do not need. I see a conflict here.
What I did advised by my doctor.
I had my last Nebido shot, and at the same time I started the following protocol:
1500iu e2d HCG (Choriomon)
300iu e2d GonalF
After 10days I could have another Nebido shot but my doctor said that would be better wait, and I did so.
4 months later in the protocol described above we had our IVF cycle and we got 3 blastocysts.
Since last Thursday I’m back on Nebido and stopped HCG + FSH (GonalF)
I guess doing Test Cyp + HCG + HMG would do the job, but for safety reasons and also to make sure you are getting the max out of your money and time I would advice, stop test and get HCG + HMG/GonalF for 3 to 6 months and the magic should happen!
Less is more, I felt not 100% during the time off Nebido but 200% worth the effort to make our family bigger!
Good luck and god bless you brother!
