HCG is considered treatment of choice for secondary (hypogonadotrophic) hypogonadism. As a LH analog, that certainly makes sense.
However, when you get right down to where the rubber hits the road, it falls short of expectations. I experimented with it for this purpose extensively on myself, and have had about half a dozen patients try it, too. Sure, you get a good boost in serum T levels, but for some strange reason, you don't really feel the benefits of it (like you do when attaining the same serum T concentration with Upjohn test cyp). It is the same situation as using Clomid as sole testosterone replacement therapy (TRT). If THAT worked, it would be great (and easy) to just have every patient take a couple pills each day.
Also, you have to use it every day in order to produce a steady serum T level. An insulin syringe works great for 500IU, but if you need more than that, then you have to do two injections (I have found that more than 1/2 cc at a time SC is uncomfortable).
That is why I abandoned Human Chorionic Gonadotropin (HCG) as sole Hormone Replacement Therapy (HRT). I use it instead to prevent atrophy of the testicles, with injections on two consecutive days each week. That also stimulates the metabolic pathway at other points as well, as LH has actions in the conversion of CHOL to pregnenolone (the rate limiting step in all three steroidal pathways).
Stone--I regularly see complete inhibition of LH production in men at 100mg per week of Upjohn. If you aren't, I'm thinking that's just because you are so doggoned TOUGH!
