Sensitive
I broke one into two peices separated by 18 mm to detect a spinning toy motor weight and by using a 8200 ohm collector resistor (that's all I had) and a 220 ohm LED resistor I got an almost perfect square wave (three corners square and one corner angled off, if I recall correctly.).

I don't know
I only took about five pills. But I think it upset my stomach slightly. And I haven't noticed any new dark hairs on the white hair only part of my chin. I may take more of the pills later as I still have 55 left.
