How to administer testosterone in Testosterone Replacement Therapy?

Testosterone can be administered in different forms. This includes injections, topicals or pellets implants under the skin. Each of these have their advantages and drawbacks and will be discussed openly.
Topical application is the least invasive, however the risk of contamination to other individuals in the home exists, and therefore rather undesirable.
Injections are probably the more common administration route. There are three major considerations with injections.
- Frequency of injection: from as infrequent as 3 – 4 monthly, to as frequent as weekly or twice weekly.
- Dose of each injection: the dose per injection is highest when injection is infrequent.
- Administration in clinic or self-administration at home
Major advances in TRT have enabled men to self-administer at home, with lower doses per injection, at a frequency of usually once a week, with an insulin sized needle. This type of protocol enables finer control of testosterone levels in order to optimize well-being.
