i read on erowid that some guy and his gf took amt and had some kinda horible kidney problem on it but they took like 100mg each, my question is do you think its safe my friend with only one kidney take AMT?

it wouldnt be wise.. i'd read all articles involving amt and read about the side effects and such before he does anything..

If Erowid or any other organization mentions even the SLIGHTEST kidney damage, I recommend your friend not do it. Try and take care of the one you have.

Injesting research chemicals won't be good for your only kidney. Assuming you are young? Take into consideration that you're going to get fat, drink alcohol and quite frankly, you're body is going to go to the shits as you age, don't speed up the process (unless you want to).
