hCG acts as an LH replacement; it does not restart production of LH or FSH. For restarting you would need to try a SERM. Conventional wisdom has said these are useless on TRT, but there's starting to be some evidence that they can work, perhaps if the TRT dose is on the lower side. Defy Medical is said to have some patients doing this.Do you have LH and FSH labs? supposedly these have effect of hormone processes and functions elsewhere (ie... adrenals, thyroid, liver, etc)..... I have low SHBG, LH and FSH was completely shut off and I was having no motivation (mental) to want to work out either although sex drive was still OK.... Anyway, I just started HCG (pregnyl) 250iu x 3/wk..... Im hoping to restart LH/FSH production and see if it has any effect on the other hormones....
