So just to be absolutely sure, I looked up the actual Material Safety Data Sheet (MSDS) for amphetamine sulphate. Sulfate, sulphate, both are correct... like gray and grey, just FYI. Sulfate seems to be a EU thing, but that's just what I've noticed, I could be totally wrong.It's not virtually odorless the way I remembered it as being. It is TRULY ODORLESS. It has no smell whatsoever to a human being, so sayeth Big Pharma. Any smell is a byproduct. Always. Forever. Every time.
