Testosterone Injections - Top 5 Frequently Asked Questions

Low testosterone levels can cause a number of issues such as low energy levels, sex drive, and muscle mass. Testosterone injections are one way to treat low T levels. Here are the top 5 frequently asked questions we get about testosterone injections.

How often should testosterone injections be given?

Injections should be given as prescribed by a physician, typically 1-2 times weekly. It is important to follow the physician’s instructions on how often to inject in order to avoid any health risks associated with over or under-injecting testosterone.

How long does one vial of testosterone last?

Vials usually last 8-16 weeks, depending on the dose prescribed by the physician. It is important to closely follow the physician’s dosage recommendations in order to make sure that you are using the correct amount of medication.

Does testosterone expire?

Testosterone expires and the expiration date is printed on the vial. After the expiration date, the medication may not work as well or may not be safe to use. Always check the expiration date before using any medication.

When will I start seeing results from testosterone injections?

Results are usually seen within 3-4 weeks but can depend on each patient. Some patients may see results sooner while others may take longer to see any changes. It is important to follow up with your physician to discuss your progress and whether or not you should continue with testosterone injections, or if you need dose adjustments.

How should I store my vials of testosterone?

Vials should be stored at room temperature in a dark cabinet away from heat sources like microwaves or refrigerators. Vials that are exposed to light or heat may not work as well and could be unsafe for use. Store your vials in a cool, dark place until ready for use.


Testosterone injections are a popular treatment for low T levels but there are some things you should know before starting injections. Be sure to talk to your doctor about the correct dosage and frequency of injections as well as how to properly store your vials of testosterone.
