Round dark green pill with AX imprinted on it?

Hi Anonymous,
You mention your pill is green - Allopurinol 300 mg with AX is white and is not your pill. Allopurinol 300 mg is white to off white, round, biconvex with beveled edge, uncoated tablet with inscription "AX" on one side and breakline on the other side...

Try a google search of .. green round ax ..
Your pill may be Armani Exchange (ecstasy) depending what part of the world you are in. There are many sites on the internet with images so a bit of googling should confirm what you have.
