Review: WARNING!!! THIS IS NOT MAMMOTH P - I have used Mammoth P for years....The liquid in this bottle is not Mammoth P ......Mammoth P only comes in clear bottles and has a distinct smell. This bottle was opaque white and had a Mammoth P sticker on it with some funky "non-smelling" liquid in it. I have asked for a refund and will not be buying from this seller again
