Okay, if I have to sum up my takeaways so far, which are only based on my personal thoughts/experiences, during the period I was on this peptide, my tinnitus baseline dropped from an always present, very piercing EEEEEEEE, to a much more diluted tone. It is not necessarily less in volume, but it is less of a piercing, visceral feeling if that makes sense. I no longer really have an EEEEEEEEE unless I do something very noisy causing a spike - this was not the case before I started on the peptide. I also had visual snow before starting this - that has remained unaffected - not better or worse. I also had back pain before starting this - that is also the same - not better or worse.
I should note that at the same time I injected subcutaneously, I underwent a few Konftec treatments both at 650nm and 808nm, so that is also a possible contributor. I spaced these out as they cause me to spike MASSIVELY which is extremely unpleasant, and I also kept them short, 10 min, but they were in the mix, just to be fully transparent. I did 3 of these, during which I immediately had a bunch of crazy noises going off in my ears - I am not sure if it healed me at all - but I definitely responded to it - I'm sure the laser does something, just not sure what (not a criticism of it just speaking based on my experience).
Additionally, I daily take chelated magnesium, fish oil, lion's mane, bioflavonoids, turmeric, astaxanthin + zeaxanthin, nicotinamide riboside, a multivitamin, and CoQ10. I was taking ginkgo and NAC but after careful testing I'm confident both of these cause my tinnitus to spike. I tried the Tebonin German Ginkgo Biloba and it brought my tinnitus back to a level I haven't experienced in weeks and cost me a night of sleep.
That all being said, my tinnitus is still here, and my hearing still has a bunch of distortion/reactivity. Once the constant EEEEEEEE was eliminated, I could focus a bit more on what lay underneath - many normal noises distort for me, and the diluted EEEEEE tone, which is sort of closer to static now, is still very audible - I can clearly hear it while watching TV for example, and it is still extremely discomforting to me. I also still have pain hyperacusis, though it has been less noticeable lately - not sure why - but it seems to be triggered less from typing on my keyboard which used to be a surefire way to get my ears to ache. Maybe the BPC has helped with that - I know BPC-157 is supposed to aid in nerve repair/regeneration.
I can say for sure on my side that nothing got worse. I am depressed but that is because of my symptoms - it was true before and it is still true now.
Lastly I think
@paul mclean also did BPC-157 and experienced a volume reduction, but our conversation in the Hough Ear Institute thread was removed as I guess it was off-topic. Just thought I'd mention in case his is another case of positive results, though I will let him speak for himself.
