I still have most of a gram of alkloid extract I got over ten years ago. I did not care for it never tried micro doses but did snort 20mg of so and I could see my heart beating on my stomach I think is pretty much bunk. All the bad effects of stimulants with no euphoria. Powerful stuff to much will send you to mental panic and physical discomfort. That is how it feels to me. Others may be diffenent.
