Drug InteractionsTestosterone cypionate may react with a number of other medications (see Drug Interactions With Testosterone Cypionate).
What If I Overdose on This Medicine?It is not known what exactly to expect from an overdose. In one case, an individual who took too much of a different form of injectable testosterone experienced a stroke, probably related to extremely high testosterone levels. Symptoms are probably most likely from chronic overdoses (taking too high of a dosage on an ongoing basis), rather than a single, one-time overdose.
If you happen to overdose on this medication, seek immediate medical attention.

What If I Miss a Dose of Testosterone Cypionate?If you happen to realize you forgot a dose shortly after the missed dose, it is usually best to take the missed dose as soon as you remember. It is probably best to then adjust your injection schedule, to prevent taking doses too close together, particularly if you were several days late with your dose.
How Does It Work?Testosterone cypionate contains the hormone testosterone in a special oil formulation that is injected into a muscle. Testosterone is slowly absorbed from the oil into the bloodstream after the injection, allowing for injections just once every two to four weeks in most cases. It works by increasing testosterone to a normal level.
Testosterone cypionate must be injected, as taking it by mouth would have little effect on testosterone levels. When medications are taken by mouth, they must first pass through the liver before they reach the bloodstream. The liver metabolizes testosterone extensively before it has a chance to reach the bloodstream, and adequate blood levels of the medication usually cannot be achieved. However, when testosterone is injected into a muscle, it bypasses the liver, allowing significant amounts of the hormone to reach the bloodstream.
