man, my friend ordered pure dxm powder online i'd say thats your best bet. i did alot of dxm for awhile and honestly it's not good for you. it took a good 3 months after i stopped to get back to a normal mental state. after we stopped using it heavily we both felt a clouded mentally. that really scared me off. it's definitely an experience, but be carefull. it's not worth fucking your brain up.
