The tin of Red Bull which I’ve got has got no manufacturers name or health warning on it???
Where did you get it? Could be old, or maybe the label was peeled off, or maybe a Chinese bootleg.
No, it’s a new tin, got it from NicotineRush. There is no sign of a label, glue or such like, on the tin.
They probably forgot to put it on at the factory. Mine has the UK version of the label. I think it came from Nicotine Rush, but can’t remember. There is no US version, as that one is not exported here directly. I can give you the manufacturer’s name if you like and also transcribe the health warning. 
I can even put the health warning in the South African form for you. 
Just let me know.
