Nolva does what is needed without the risks for some of severe estrogenic side effects. Clomid has a lot of research because it is old and was first in the game. The fact that clomid is used a lot and recommended over and over again does not mean that it is the best or safest SERM. If you know that you tolerate clomid, use it if you need a SERM.
I asked if you had read the stickies as T+AI+hCG will do what you are wanting. TRT without hCG is very high risk for fertility. [Most guys here are older and maintaining testes for self image, for wife or GF and for pregnenolone production.] Note that male contraceptives that cause HPTA shutdown do not have any reputation for really working well either - and have never been commercialized.
Your T levels one week after injecting are very good and unexpected. It would be better to test 1/2 way between injections and better also to inject at least twice a week. You may feel better.
Adex cannot properly manage E2 levels with weekly injections as T levels are changing to much. And T peaks from weekly injections also create higher amounts if E2 and SHBG.
Understand issues and changes for anastrozole over-responders.
All of the above can be found in the stickies. You did not come back for clarifications of these points.
Try T+AI+hCG and then have a sperm count done later on to see how you are doing. hCG does have some cross activation of FSH receptors. If the testes are maintained, a SERM or HMG can always be introduced to improve fertility when needed. There really is not a strong argument to stay on a SERM or HMG permanently -or long term. Long term SERM use has risks as well.
"Any thoughts on stopping Test Cyp in favor of HCG, etc. and/or doing both? "
If hCG increases T, HPTA shutdown and low FSH should result. In that regard, your question does not make any sense as you have HPTA in both situations. If you are younger and have healthy normal testes, secondary hypothyroidism, then you could be a candidate for LH replacement doses of hCG, 250iu SC EOD. Do not get into high dose hCG as you can induce primary hypogonadism. Again, hCG can shut off LH and FSH.
I don’t think that you should stop TRT.
Most injectors do this, which others have coined the ‘standard protocol’.
100mg/week T ester injected twice a week or EOD, can be IM or SC, can use insulin syringes
1.0mg anastrozole per week in EOD divided doses [difficult with 1m tabs]
250iu hCG SC EOD
Refine adex dose to get near E2=22pg/ml. Come back for dose correction calculations if you have not otherwise found that.
