A formulation delivery system includes a cartridge, a control unit, and a stiction breaking element. The cartridge includes a reservoir chamber, a bolus chamber, a reservoir chamber piston, and a bolus chamber piston. The reservoir chamber piston is configured to move within the reservoir chamber to expel formulation from the reservoir chamber into the bolus chamber. The bolus chamber piston is configured to move within the bolus chamber to expel the formulation from the bolus chamber to a patient. The control unit is configured to engage with the cartridge and includes a control configured to activate the reservoir chamber piston or the bolus chamber piston. The piston stiction breaking element is configured to break a stiction between the reservoir chamber piston and the reservoir chamber or between the bolus chamber piston and the bolus chamber.
