Okay, I'm assuming you got BDNF at Korea. You seem to be open to ideas other might deem fruitless, so let me ask you this. I've been researching BDNF for a bit, so I'm not trying to act like a pro on the topic, but in theory, it would seem to me like, if we could boost our BDNF through exercise, diet, and supplements, then maybe we can regenerate some synapse nerves? Since many reports point at BDNF as being able to help restore our synapses, and well that seems to be what Otonomy is using for OTO-413. Of course Otonomy may be using a higher concentration that we can't naturally produce. Something to ponder.
Also, I wish this thread got more love. There might be something here.
