Mda??

I suspect a friend may currently be on MDA as opposed to what was supposed to be MDMA. To those who are familiar with it, what should users be wary of and how would we know better whether it's MDA or not?

You could always send the pill/powder/whatever your friend bought in for testing. Pressed pills cost $40 dollars to get tested everything else costs $120. (edit: I'm not sure if they take samples from Canada. Nevermind I think they do.)

The standard screening kit can differentiate MDA from MDMA/MDE.

You can compare the effects and dosages at erowid.

MDA kicks MDMA's ass hard.

I enjoy mdma

been awhile

mda kicks in very quick if you chew, less than five minutes..you feel like a blanket has been wrapped round u and you sweat balls. MDMA, chew and it kicks in after 15-30 minutes, sweat but not as intensely.

MDA is more controllable experience. MDMA is like flying and not being able to hold onto a compass.

some one hook me up wit some mda shit would go like candy out here

we got bombs out here but aint none like pure mdma uk
