Olfactory Transfer?? Peptides passing BBB

From Wikipedia, "The major part of the approximately 150 cm2 surface in the human nasal cavity is covered by respiratory epithelium, across which systemic drug absorption can be achieved. The olfactory epithelium is situated in the upper posterior part and covers approximately 10 cm2 of the human nasal cavity. The nerve cells of the olfactory epithelium project into the olfactory bulb of the brain, which provides a direct connection between the brain and the external environment. The transfer of drugs to the brain from the blood circulation is normally hindered by the blood–brain barrier (BBB), which is virtually impermeable to passive diffusion of all but small, lipophilic substances. However, if drug substances can be transferred along the olfactory nerve cells, they can bypass the BBB and enter the brain directly.,[11][12]
The olfactory transfer of drugs into the brain is thought to occur by either slow transport inside the olfactory nerve cells to the olfactory bulb or by faster transfer along the perineural space surrounding the olfactory nerve cells into the cerebrospinal fluid surrounding the olfactory bulbs and the brain (8, 9) [13][14]

Yeah, supply chain losses are going to be normal even aside from human error, in any industry (like you said).
I actually meant hopefully you're the only one who got DXM in this case. I don't want some senator's kid to drive while tripping and get the whole industry legislated to death before I've even had a chance to dabble in it.

I am 99% certain other vendors got this "Bromantane." My supplier told me that they have sold it to many other vendors, and nobody has complained.
