Hello everyone I found an article on a forum that talks about testicular desensitization, HCG and HPTA recovery.
I quote you what it says.
I am sure that on this forum you are experienced on the topic.
"Testicular Desensitization
Although steroids suppress testosterone production primarily by lowering the level of gonadotropic hormones discussed above, the big roadblock to a restored HPTA after we come off the drugs is surprisingly not the level of LH itself. This problem is made clearly evident in a study published in Acta Endocrinologica back in 1975(1). Here blood parameters, including testosterone and LH levels, were monitored in male subjects whom were given testosterone enanthate injections of 250mg weekly for 21 weeks.
Subjects remained under investigation for an additional 18 weeks after the drug was discontinued. At the start of the study, LH levels became suppressed in direct relation to the rise in testosterone, which is to be expected. Things looked very different, however, once the steroids had been withdrawn (see Figure I). LH levels went on the rise quickly (by the 3rd week), while testosterone barely budged for quite some time. In fact, on average it was more than 10 weeks before any noticeable movement started.
This lack of correlation makes clear that the problem in getting androgen levels restored is not the level of LH, but in fact testicular atrophy and desensitization to this hormone. After a period of inactivation the testes have apparently lost mass (atrophied), making them unable to perform the workload required by heightened levels of LH.
Post-Cycle LH Levels "
HCG
So we now see, contrary to the dominating opinion of the times, that anti-estrogens alone will do little to raise testosterone levels in the early weeks of the post-cycle window. This leaves us to focus on a very different level of the HPTA in order to hasten recovery: the testes. For this we will need the injectable drug HCG. If you are not familiar with it, HCG, or Human Chorionic Gonadotropin, is a prescription fertility agent that mimics the bodies own natural LH.
Although the testes are equally desensitized to this drug as LH (they both work through the same mechanism), we are administering it as a measured drug and are therefore not constrained by the limits of our own LH production. We similarly can use HCG to provide a bolus dose of LH (of our choosing), which works only to augment the recovering LH levels we already have in the body. In essence we are looking to shock them with an overwhelmingly high level of LH activity, coming from both endogenous and exogenous sources.
We want it to reach a level far above what our body, even when supported by anti-estrogens, could possibly do on its own. The result can be a rapid restoration of original testicular mass and functioning, which would allow normal levels of testosterone to be output much sooner than without such an ancillary program. What we are looking at now is HCG actually being the pivotal post-cycle drug, while anti-estrogens are relegated to a supportive role at best.
Finalizing The Program
An ideal post-cycle recovery program will focus on two things really. The first is hitting the testes hard with HCG. It is important, however, not to overuse this drug. Taken for too long, or at too high a dosage, the LH receptor will actually become desensitized to LH(2), which may further exacerbate our post-cycle problem instead of helping it (this is why I am not in favor of regularHCG use on-cycle). My experience with HCG has led me to feel comfortable using it for a course of three weeks, at a dosage of maybe 5000-7500IU weekly.
Often the last week I limit the dose to 2,500IU, unless the cycle has been particularly long or potent. This is timed so at least half of the total administered drug dosage will be given when there is still exogenous steroid in the body. On our graph above this would be at about the 3-week mark after the last injection of testosterone.
This will give the testes some time to get back into shape before the baseline is actually hit with T levels. Secondly, Anti-estrogens are used to play a supportive role at the same time, so 20mg of Nolvadex or 50-100mg of Clomid would typically be added (my last article for Mind and Muscle discusses the comparative differences with these two agents). This is to combat the suppressive effects of estrogen as testosterone levels start to go back up, as well as potential side effects (HCG has been shown to increase testicular aromatase activity as well (3)).
Although in the first couple of weeks the anti-estrogen does little, it may indeed be helpful when testosterone levels actually start to get back up near normal. To further stimulate the HPTA, and support continuingly high LH levels, the anti-estrogen remains to be used for 2 to 3 weeks after the HCG therapy has been stopped."

What do you think, is it correct or is it a wrong theory?
Is important your opinion, thanks to all.
