one of my friends used to be prescribed this for weight loss
it was called phentermine or fastin. they were little capsules. it was a prescription though. it was not otc.
we heard it was supposed to be speedy, opened one, and snorted the powder.
it didnt do anything for me other than it gave me a horrible headache and it was extremely painful.
it was more painful than meth
my friend did not find it as horrible as i did, but there is no way in hell i would do it again. The capsules were like 37 mg or something i cant remember the color of them.
