Interesting, however I haven't heard of excessive repetitive injections.
The more research I have done on it, whilst still promising, regardless how you look at it right now, is that injections have lasted between, no effect, 1 month and up-to 2 years, before the next injection. Journals seem to be providing more accurate information than that of websites sensationalizing it and leaving out the current set-backs.
Right now, it is a sensational treatment opportunity, IMHO, for anyone with PTSD, however; there is a lot of unknowns to this as well, especially long term effects, which nobody, not even Lipov himself from admission, can clearly state is safe long term, or for how long it can be administered, ie. how many injections, without permanent damage occurring.
Because of the nature on where the shot is, whilst this procedure has helped in other areas, the specifics in relation to literally numbing the c6 vertebra, which the consequences are simply unknown.
What is positive though, is that Lipov is starting to get some interest from backers, and the psychiatric community for further study, but they want to see studies, theory, results, consequences, etc.
I would agree that on one end there is skepticism, and the other a really positive outlook for PTSD. I can also see how the mental health industry, along with pharmacology, could get a little offended if suddenly you remove the need for a large chunk of SSRI's being sold, or psychotherapy under-taken. I see some truth in some aspects of the conspiracy theorists in that regard. A lot of powerful and influential people will suffer by losing out $$$. Saying that, anyone who jumps on that right winged agenda alone, without reviewing all the factual journal documents and self admissions by Lipov himself, are nut jobs, to put it bluntly.
Like Lipov himself admits, right now, there is a real positive hope that this one treatment could help a majority of people long-term.
Even if this is only a bandaid, which Lipov admits it is, but a damn good one that allows a person to near instantly move past a whole bunch of built-in fears produced by trauma. This could reshape the healing process of trauma in general if it has little to no major long term health issues. Do you imagine being isolated in your home for years due to fears, anxiety, etc, then suddenly they don't exist any more? That one feat surpasses all exposure therapy in one sitting... achieving what one could only ever hope to achieve through years of exposure therapy.
If the people work on the trauma during the first shot... hell, even after it wears off, the potential for relapse alone could be marginalized, with less relapsing into a traumatic self environment and PTSD diagnosis.
