There are not good alternative for teste size, or at least none as good as HCG with as few negatives as it has other than price.

In those reports, it is likely that the person's Estrogen was lower than normal or overly suppressed by AI, and by adding HCG helped raise it. Too much Estrogen is bad, but too low or bottoming it out can be just as bad for libido/function/mood. That would be the main guess, and that it was not the HCG itself.

For strictly ED concerns or just fullness in general Cialis will perform better than HCG and is much cheaper usually.

There is a recent trend of some people using SERMs (clomid or enclomiphene) while on TRT as an alternative to hCG to maintain testicular function.

This seems to have mixed results from patients that we have spoken to that have been on that regimen before, though we at AlphaMD do not recommend that approach. SERM have the well documented side effect of blocking IGF-1 production, which is a necessary component to many of the health benefit of being on TRT in the first place.

There are menotropin medications available, which act on FSH and LH receptors. Technically speaking, they would be better options than hCG, which only attaches to LH receptors (not FSH). However, the cost of menotropins are astronomical and not acceptable for long term use.

Anecdotally, many men have reported improved libido and better erection quality on hCG. There are zero actual human studies on this, so at this point it is officially bro science.

As far as a "fuller" penis,tThere is one study where hCG was used on men with micropenis, and there was some successful growth, but it was not enough to be considered a successful treatment. There was one study on rats where the used hCG combined with a vaccuum device as well as LOX inhibitors, and the erect penile size increased by 3%. No studies have shown increase in penis size on post-pubertal men who do not have a micropenis.
