Unless rubbing your nipples is part of your job, anyway.. Andractim testosterone gel is a topical gel, which comes in a tube, containing 80x 25mg doses of DHT.

Servo Motor Applications. Servos are used in radio-controlled airplanes to position control surfaces like elevators, rudders, walking a robot, or operating grippers. Servo motors are small, have built-in control circuitry and have good power for their size.
In the context of audio circuits, a servo is usually an active element used in feedback in order to null or reduce an amplifier's offset voltage. Consider Fig. 1. On the left is the schematic for a differential operational amplifier (op-amp). On the right is the symbol usually used to represent this type of circuit.
