If anyone is willing to help me evaluate the legal feasibility and find places that would be willing to do standalone IGF-1 intratympanic treatments, I would appreciate it.
According to what I have researched, IGF-1 is approved by the FDA, which would make off-label use possible. The problem is that it's illegal for sports use and has a slight risk of inducing type 2 diabetes if used too much as a form of continuous long-term treatment. This is what I've gathered from what I've read, but other perspectives would be appreciated.
Personally, if it's legally feasible, I am willing to take that risk, because it would be at such a small dose and would not be a regular thing at all. In addition, the scientific papers in relation to the cochlea and IGF-1 have made this very compelling. So, if we can see whether or not these American clinics, who should likely be far more knowledgeable about the risks of IGF-1, would be willing to discuss and try this, that would be wonderful.
I am writing this request here since people here are already discussing a lot of possible clinics for Stem Cells and PRP injections, although maybe it would be better in a PRP thread. Not sure.
IGF-1 is in PRP, but the amount of it varies per person, and of course there are the issues of making sure intratympanic injections get everything in the right place. I have been hoping standalone IGF-1 could solve a lot of these issues, as well as the cost, because it may actually cost $500 per shot, which sounds like a lot better deal compared to Stem Cells and PRP if it works, since it's be more potent and supposedly less expensive.
Update:
A few things that I have picked up from research (with the help of ChatGPT). There are about 10 studies that show effectiveness of standalone IGF-1 that mention the dosage used. On average, they're presumably 150 micrograms total from three shots. This dosage amount is considered safe, but it's still not naturally produced IGF-1. The potential cost is still unknown, but may be between $500-$2000. The PRP equivalent that would likely have 150 micrograms of natural IGF-1 would be 150 mL, which would likely be on average $6,000.
I would prefer IGF-1 and PRP because there's more publications of their effectiveness for the cochlea, as opposed to stem cells, and yet the people that did PRP for older injuries have not reported good results.
