so my dad's zapper got stolen before he got it. grr.

I have an RSG-2 that I'm considering lending him (if it doesn't sell here) but I'm worried because he takes different medications. On toolsforhealing.com it says the RSG-1 is like a high end zapper with different frequencies.

are there certain frequencies that concentrate medications in the blood like Dr. beck warns? or is it all of them?
