I love the results where the laser beam can barely be seen in a dark room for 20ppm silver, where 20ppm is confirmed by a calibrated Hanna PWM Meter compared to a known 20ppm solution of CS.
The CS I make is clear @about 10PPM according to my TDS meter shows a solid laser light in a dark room.
I also take it sublingual for internal directly into the blood. I don't know why anybody wouldn't want it to enter damaged cells.
