I am posting a PM reply to the OP I made, here, as I think it be of help to other men in a similar situation.
"When you had your original diagnosis by the doctor for your low T, was it determined that you were either primary or had secondary hypogonadism? If you do not know what this means: Primary refers to a determination that the testicles are at fault as they are not producing high enough levels of T, even though they are getting ample stimulation from the pituitary from high levels of LH and FSH (gonadotropins). Secondary refers to a determination that the Pituitary is at fault as it is not producing high enough levels of LH and FSH. This will be evident from the testing they did. If you were primary, there may be less to no chance of the below restart working for you. If you were secondary, much better chance. Most men suffer with secondary hypogonadism, not primary so there is good chance this is what you have.
The younger you are, the better the chance you have of this working. Older men in their 40’s and 50’s will probably do better on T replacement.
Given that you have been shut down for many years now, it would most likely be necessary to give your testes a kick start first with HCG or Ovidrel. Dr John Crisler (more on him further down) was very good at restart protocols for guys who had been on steroids for many years. He often said that the testes were the slowest to respond when compared to the pituitary when trying to get the HPTA running again, especially if they have atrophied considerably. HCG will give them the stimulus that is sometimes required to literally wake them up quicker than if just a SERM is used on its own.
Typical dosages for this would be from 250 to 500iu 2-3 times a week. The course of HCG is run for around 4 weeks, during the last week SERM treatment usually begins.
Be wary of doctors who suggest using more than 500iu per shot of HCG. Dr Crisler said that injecting more than this each time was not needed and could actually desensitise the leydig cells in the testes to your own LH. Not what you want to do!
SERMS are drugs classed as selective estrogen receptor modulators. They if used correctly can stimulate the pituitary and hypothalamus to start producing higher levels of GNRH and therefore LH and FSH. These gonadotropins tell the testes to start producing testosterone and sperm.
So as HCG has already turned the testes back on so to speak and they have grown in size which is the important part, they will be ready to accept the stimulation very well from your own natural gonadotropins: LH and FSH. Sometimes if SERM treatment is started on its own without HCG, the restart protocol can take much longer to work (or not work at all) as they testicles can be quite stubborn due to the degree of atrophy (shrinkage). As you have been on a relatively high dose of testosterone for many years, I would suspect they are quite atrophied.
The hypothalamus and the pituitary have not atrophied due to your testosterone replacement because they produce other hormones which are not affected to any great degree. They start to produce GNRH, LH and FSH fairly quickly given the stimulation from a SERM.
Have you noticed that your testicles have shrunk considerably from before you undertook TRT?
Did your ejaculate also diminish markedly?
Has your refractory period also increased noticeably (the time period that you are able to ejaculate again as in hours, days for example)?
Have you noticed a loss of sexual sensation in your penis since being on TRT?
The most common SERM used for this is Clomid, or its drug name clomiphene citrate. It has been around for a long time. It’s a tablet so it is much easier to take than HCG which is a subq injection. Dosages are typically around 12mgs per day (A doctor who has experience and consults with you, will know best with regard to dosage). This course may need to run for much longer; 3-4 months with a very slow taper at the end. The
TAPER is
VERY IMPORTANT so as to not shock the HPTA by sudden withdrawal of the stimulus of the drug.
During this treatment it’s a good idea to get testing done to see where your levels of T and LH and FSH are at various times. Because of the nature of Clomid, most guys do not feel as you think they should with a higher level of T and the other hormones as a consequence of treatment. This is because these drugs also stimulate the estrogen receptor and cause issues there. Sexual function can be all over the place and some men can also feel moody or emotional at times. Some guys do not get these side effects as strongly as others.
There was a newer SERM developed by a company called “Repros therapeutics”, who tried for many years to get approved by the FDA for the use of stimulating higher levels of natural testosterone on a permanent basis. This drug was called Androxal and it is Enclomiphene citrate.
Clomid which is Clomiphene citrate is made of two parts: Zuclomiphene and Enclomiphene citrate. It is considered that the Zuclomiphene part of Clomid is the part which generates most if not all of the undesirable side effects Clomid can have. So Repros simply removed that part from the compound. Androxal raised natural testosterone in individuals with secondary hypogonadism quite well, comparable to that of T gel administration. However, the FDA after many years of trials, did not give them approval, so the drug never came to market even though it was safer to use than Clomid. Some doctors still prescribe Clomid for HRT in men on a permanent basis, which maintains fertility and natural T. Dr. Crisler said he was never comfortable using Clomid long term due to its estrogenic properties.
Many men who have tried Clomid for permanent HRT purposes do not stay on the drug because they do not feel any better whilst on it owing to the side effects even though their T level is much improved.
I have heard that Enclomiphene citrate is being compounded in the US now and is available. I am in Australia and do not have access to it, but you may do. Enclomiphene has all the same properties for a restart drug as Clomid does, very possibly without the side effects of Clomid.
If once you have tried a restart protocol and your HPTA does not respond as hoped, i.e. your T levels remain very low after discontinuation, which is a possibility given the time you have been on TRT. There is also a possibility that you could remain on Enclomiphene permanently to keep the stimulation at the pituitary to produce higher levels of gonadotropins. The dosage needed for this may be less that what is needed for a restart.
One thing to be aware of is that proper sexual functioning can take some time to return properly after a restart protocol has been performed. It takes time for the body to find homeostasis again if it can.
I think it always preferable as I mentioned in my posts to you, that for a young man, everything should be tried first before undertaking TRT. It appears the doctor who saw your originally decided to put you straight onto T replacement without any attempt to improve your natural T.
TRT will never replace the optimal functioning of a healthy hormone system in a young male. It can attempt to, but things will not be quite the same. If that is all that can be had, it can be better than having very little to no testosterone at all!
Defy medical in the US is where I have heard that you may be able to get Enclomiphene prescribed and supplied and they also specialise in HRT for men. So if the end result is that you do need to remain on testosterone replacement, they may be better equipped to help and advise with this.
https://www.defymedical.com/Unfortunately Dr John Crisler passed away 2 or more years ago, otherwise I would have suggested him for you without hesitation. Many of his protocols and techniques have been carried on by other doctors who followed him. He ran an online forum for many years called “All things male” which I was a member from its inception. I learnt a great deal from him and other members, some being his patients who were dealing with testosterone replacement. Many guys came to this forum who were having considerable issues with doctors who were using outdated methods to manage low T.
He did write a book on the topic which you may find useful:
https://www.amazon.com.au/Testosterone- ... B00UPN8JFUI hope this helps you. Testosterone replacement for men is a very tricky endeavour which some doctors are not very good at navigating.
There is also another forum, that seems to have taken the place of “All things male” since. There are some good people posting there with considerable knowledge on the topic who may be able to help even further that I can. Frank talk is much more concerned with ED.
https://www.excelmale.com/forum/There is even a sub forum on that site, just for restarts and SERM therapy and discusses drugs like Clomid in detail.
https://www.excelmale.com/forum/forums/ ... -low-t.89/Try and not get to overwhelmed by all the information on that site, take your time and possibly talk to and read the posts of one very intelligent member there called “Cataceous”. Nelson Vergel is the founder or the forum and you will see a great deal of posts by him.
One point I should make after mentioning all that I have to do with hormones, is that your ED may not resolve after the successful reinstatement of your natural hormones. Your ED issues may be from another cause than what was originally thought to be low T.
However, I do not think the very high dose of T that you are on is helping matters with your ED and may have even made it worse as I discussed in my post to you. So it could be that after your natural hormone milieu is in place again, you may have a better response from PDE5i at a lower dose.
I would think even a better managed TRT protocol could also encourage this."
