@KuKaneLono A recent study goes into how nasal (although in this case inhaled) NO can be used to mitigate covid. A benefit of 'Nitricil' is it can be applied directly to the lungs. In gel form 'nitricil' could possibly be applied as a preventative measure nasally as a 1st line defense. Accumulated DD thread: twitter.com/konahuanui/stat...
