i'm new to this world. I am not trying to find a source for any pct's, but I am curious about the legality of ordering them online. I live in the u.s. and know that at one time scientists were allowed to order these research chemicals to test on rats. I am an up and coming biology major and test levels part of my studies. If anyone could let me know what the rules and regulations are on these nowadays are I would appreciate it. Thank you.
