You ain't gonna get N in India because they use different medicine to euthanize animals
N is only used to euthanize animals, no medical use for humans
In India mostly they use Thiopental sodium (Thiazol®) at higher dose animal will go down within 10sec maximum then they use MgSo4( magnesium sulphate ) along with Thiopental sodium and apart from Thiazol ® phenobarbital for euthanasia
