10. A method of administering testosterone comprising:
administering a preservative-free composition comprising a unit dose of testosterone or pharmaceutically acceptable ester or salt thereof in a pharmaceutically acceptable carrier subcutaneously to a mammal,
wherein after administration the plasma level of testosterone is maintained at a therapeutically effective level for a Z2 time period,
wherein the Z2 time period is at least 1 day, and
wherein administering the preservative-free composition consists of a single injection via a powered injector comprising a housing, a chamber disposed within the housing and configured to receive the preservative-free composition, and a needle operatively associated with the chamber.
11. The method of claim 10 , wherein the preservative-free composition comprises a liquid composition.
12. A method of maintaining elevated plasma levels of testosterone in a mammal in need thereof comprising administering a preservative-free composition comprising:
a unit dose of testosterone or pharmaceutically acceptable ester or salt thereof in a pharmaceutically acceptable carrier subcutaneously to a mammal,
wherein after administration the plasma level of testosterone is maintained at a therapeutically effective level of up to about 1800 ng/dl for a Z2 time period,
wherein the Z2 time period is at least 1 day, and
wherein administering the preservative-free composition consists of a single injection via a powered injector comprising a housing, a chamber disposed within the housing and configured to receive the preservative-free composition, and a needle operatively associated with the chamber.
