Testosterone should always be in a liquid state for injecting. It is rare, but sometimes testosterone can crystallize inside the syringe if it reaches temperatures below 68 degrees Fahrenheit. It is still safe to use but needs to be dissolved before it can be injected.

To do this, place the syringe in a sealed plastic bag.

Place the sealed bag into warm water not over 104 degrees Fahrenheit.

Let the bag remain in the water until the testosterone is dissolved and returns to a liquid state.

Allow the syringe to cool off to room temperature. You are now ready to inject.
