Coley's Toxins and CHIPSA

I had heard about Coley's Toxins through this NPR article:

http://www.npr.org/sections/health-shots/2015/12/28/459218765/cutting-edge-cancer-treatment-has-its-roots-in-19th-century-medicine

and had forgotten all about it until someone mentioned it in a group that I'm a part of, specifically, the version being offered by CHIPSA in Mexico:

The video is actually factually correct up until the service-selling portion. I was wondering if anyone had any experience with it and how they felt it rated against Dr. Raymond Chang's offerings here in my hometown of NYC?

Anyone have any experiences to share?
