In order to "pump" 125 mA of current through the body, you would need a *very* high output voltage. Let's assume that the resistance of the body between the hand-holds is 1K Ohms. It isn't, that number is too low, but that makes this example better (and the math easier). To push 125 mA through 1K, you need an output voltage of 125 Volts. Yeoww, and OUCH. And it amounts to over 15 Watts *delivered*. More OUCH.
So it really doesn't matter what the *maximum* output current is; what matters is how much of it is actually flowing in your situation, with your skin resistance, your handles, your sub-cutaneous fat layer thickness, etc.
