I am appreciative of the qualifications of my posts by others so as to not take my writing out of context. But, it is clear from posts that many believe that hCG desensitization occurs at levels over 500 IU. Even though Crisler does qualify his statement as pointed out, the inference is that doses higher than what he advocates will cause desensitization. He is wrong. Further, I find his grasp and understanding of the literature to be wanting. And that is putting it kindly.
hCG desensitization does occur in cases of prolonged administration of 5,000 IU (Five Thousand). But, even here it is not a given and does not occur often and consistently. I am in total agreement with the immediate posts that this problem is almost never observed in clinical practice. Why the continued worry and hype about this problem is beyond me, but possibly Crisler helps feed this false idea.
I also agree with an earlier post in this threads that the two studies mention do nothing to support or demonstrate desensitization or the use of 250 IU X2 as useful therapy. If you really think about it, what is the purpose of the hCG two days in a row. This is totally and completely bizarre. As before, I challenge anyone to provide literature (article or citations) in support of his treatment(s). If Crisler is so sure of himself, why does he not cite support for the therapy or better publish the treatment. I have a simple answer - it is all in his head.
In the spirit of not repeating myself too much, I will repost some of the information from prior posts on this hCG question.
The study referenced, ***65533;Coviello AD et al., (2005), Low-dose human chorionic gonadotropin maintains intratesticular testosterone in normal men with testosterone-induced gonadotropin suppression, J Clin Endocrinol Metab. 2005 May;90(5):2595-602,***65533; will give some insight to the current hCG regimen that some of the forum members currently use with their TRT!!!
First, this is a study on intratesticular testosterone (ITT). The participants in this study were treated with T enanthate (TE), 200 mg im weekly, for rapid gonadotropin suppression in conjunction with a variable dose of hCG, delivered sc every other day for 3 wk: 0 (saline placebo), 125, 250, or 500 IU hCG. The placebo group served as the control group. [Note: Do you see a difference already! Even though the study does bot support Crisler, the dosing is much different.]
So, what we have are male subjects with elevated T levels due to exogenous T enanthate. Their endogenous production of T is completely suppressed (theoretically) as are their gonadotropins. ITT is suppressed due to the inhibition of gonadotropins from the exogenous T enanthate.
They found that each dose of hCG (125, 250, and 500 IU) returned the ITT concentration to normal. The data set being measured was not serum T, it was ITT. This should alert one to the stupidity of the research design. This was a waste of resources, in my opinion. The very simple reason is that in a normal male with a normal serum T their ITT will be ***65533;normal.***65533; All this study did was take a normal male and replace his T with exogenous T and than give hCG which replaced his LH. Duh ***65533;
The one saving grace for the study is that it will be instructive to those using low dose hCG with their testosterone replacement therapy (TRT). It does tell us something about hCG therapy while on testosterone replacement therapy (TRT). I mentioned above that if one is going to use hCG while on testosterone replacement therapy (TRT) they should have something to observe, measure, and document. Why? If you are taking a drug, any drug, and do not have a dataset to monitor the effect of the drug you need to seriously think about what you are doing. I would ask them when did you decide to relinquish the control of your body?
It would be of interest to look at the data on serum T changes with each hCG dose . The subjects are on T enanthate so this is very similar to those on hCG with testosterone replacement therapy (TRT). The finding is that the dose of hCG 125 IU every other day had NO effect on the serum T. The two higher doses did raise the serum T levels above normal. [Note: recall the dosing schedule!!!]
There is no individual data (always a cause for suspicion when reviewing literature) and there are no significance levels. Visual inspection of the graph, however, shows that the serum T level was not significantly different from control until day 21. If I was administering hCG less frequently than every other day and had no dataset to monitor I would be concerned.
Posters will do what they wish regardless of the literature. I respect that, particularly if someone feels they are getting a clinical response. I have treated over a 1000 patients for AIH and more for testosterone replacement therapy (TRT). I did take the effort to research the treatments. And when I did develop a treatment for AIH, I published and presented the findings. I just happen to be skeptical of others who tout therapies based on their experience that has no basis in the literature. Further, they are treating patients as guinea pigs!
