What about the use of clomid in addition to test injections? The idea is to "naturally" stimulate the testes' own LH and FSH production instead of relying on artificial HCG.
This is exactly what my doctor had me do, Androgel 1.62 4 pumps ED, and 25mg of clomid E3D. I have been on TRT for 7 months. I do believe this is the reason my balls have not shriveled up! My TT was 400 before starting Androgel. I am trying a clomid restart to see if my own production will come back. I went on TRT in hopes of improving my libido. It has not had that effect, in fact it is actually worse.
A few years back, I did try the clomid test. Sure enough, I was able to raise my test levels up past 750 in only 3.5 weeks. My levels at the time were 350.
It does work, but there are the sides to contend with.
