Testosterone is a male sex hormone produced in the testes and adrenal glands and is responsible for the development of male sexual characteristics, such as a deep voice, body hair, muscle growth, and libido.
Testosterone levels increase during puberty and gradually decline after the age of about 40 years. This may cause reduced sex drive and erectile dysfunction in some men.
Testosterone replacement therapy helps increase testosterone levels in the body. Testosterone replacement is available in several forms including patches, gels, injections, creams, nasal gels, capsules, and tablets.
Although the best and most effective form of testosterone depends on the reason for supplementation, personal preferences, and financial picture, testosterone injectables are the ones that are most often and commonly used in clinical practice.
What are the different forms of testosterone supplements?
Testosterone replacement therapy (TRT) is recommended to balance or boost the amount of testosterone in the body when the levels fall below 300 ng/dL. Six forms of TRT include:
- A transdermal patch (skin patch) Applied on the arm or upper body one time a day. FDA-approved two testosterone transdermal patches include: Androderm Testoderm
- Applied on the arm or upper body one time a day.

- Injections Testosterone injections are one of the first forms of TRT that were approved for use. Testosterone is injected directly into the muscles or under the skin. Popular brands of testosterone injections include: Depo-Testosterone (testosterone cypionate) Delatestryl (testosterone enanthate) Aveed (testosterone undecanoate) Testopel (testosterone pellet) Ditate-DS (testosterone enanthate) Four types of injectables include: Enanthate: A derivative of the primary endogenous androgen testosterone for intramuscular administration. Cypionate: A long-acting eight-carbon ester form of testosterone, which is metabolized in approximately seven to eight days. Propionate: A slow-releasing anabolic steroid, which peaks in the blood within hours of being administered and is metabolized over three days. Testosterone suspension: Water-based testosterone without ester, which is the most powerful injectable steroid available, encouraging quick muscle mass and strength.
