I have no idea if this is where the Prazi I used was purchased from. I'll find out sometime next week for sure, but in the meantime, I emailed them and asked about their source. Here is "fishhchemical.com" response. I assume the reference to purity to 101% is a type-o...hopefully.

The material is Chinese, USP grade(human grade). It is tested only by manufacturer and purity runs 99.1% to 101% SEMNFreeze@aol.com [mailto:SEMNFreeze@aol.com]

May I inquire about your source for Praziquantel? What country? Is it tested for purity by the FDA when imported?
