Ok so rather than daily HCG, in your opinion (for those who require it during TRT), what is the best way of implementing it? 250iu twice a week perhaps?
I am not being difficult, but first one must decide what is the purpose of the hCG. Following is some info on Extragonadal Luteinizing Hormone / Chorionic Gonadotropin Receptors [LH/hCG-R].
There have been some statements that there exists Extragonadal Luteinizing Hormone / Chorionic Gonadotropin Receptors [LH/hCG-R], particularly within the Central Nervous System (CNS), that are functionally significant. Moreover, they use these statements as reasoning for the use of human Chorionic Gonadotropin (hCG) within Testosterone Replacement Therapy (TRT). Not surprisingly, these practitioners provide no evidence foe these claims. [IIRC, they point to a possible short feedback loop as evidence, which is unproven. If this is the evidence for its use, then any drug is okay for just about anything!

In a 2007 review, the authors’ concluded, “further evidence is needed before the extragonadal LH/hCG-R expression can be considered functionally significant.” In a recent communication a study author stated, “Further information is accumulating, but I would still stick to our old original conclusion. You can find recent publication on LHR expression in the uterus, but I am still not convinced about their functional significance.
There is NO, NADA, ZIP, ZERO evidence for functional Extragonadal Luteinizing Hormone / Chorionic Gonadotropin Receptors [LH/hCG-R] within the CNS and more especially in males.

Gonadotropins are indispensable in both sexes in the regulation of gonadal sex steroid production and gametogenesis. In addition to their well-established classical actions, numerous recent publications have indicated the presence and function of luteinizing hormone/chorionic gonadotropin receptors (LH/hCG-R) in a variety of extragonadal tissues. However, the physiological significance of such effects has remained unclear. We have generated two genetically modified mouse models, one with excessive production of hCG and the other with targeted disruption of LH/hCG-R gene, and used them to address the functions of LH and hCG. Numerous gonadal and extragonadal phenotypes were found in the models with the two extremes of LH/hCG action. However, when the extragonadal effects were scrutinized in greater detail, they all appeared to arise through modification of gonadal function, either through enhanced or inhibited response to LH/hCG stimulation. Hence, further evidence is needed before the extragonadal LH/hCG-R expression can be considered functionally significant.
