I have been in and out of this stock several times since 2009----it was once over $1.00---very fast run up and then sub penny---
I have used the Cobroxin and am currently , along with my wife , using the Nyloxin.
It has been very effective as a pain reliever for my wife's severe arthritic pain in her back---she suffers from arthritic scoliosis and the Nyloxin has REALLY out performed itself here----there were days when she could not get out of bed---due to the pain....
Purchased the roll on from Ebay---inexpensive....works like a charm and she has no problem getting out of bed now...use it at night and in the morning.
