Testosterone Replacement Therapy (TRT) is made from different forms of testosterone designed to restore hormone levels in men with low testosterone. These include synthetic or bioidentical versions that closely match the testosterone your body naturally produces. The formula depends on how it’s delivered—by injection, gel, patch, or oral capsule.
What Is TRT Made From?
TRT uses synthetic or bioidentical testosterone to help men regain energy, muscle mass, sex drive, and mood. The hormone in TRT is designed to act just like your body’s natural testosterone. Depending on the method of delivery, the ingredients may vary slightly to help with absorption, effectiveness, and safety.
Common Testosterone Types in TRT
-
Testosterone Cypionate – Long-acting injectable, widely used in TRT programs
-
Testosterone Enanthate – Similar to cypionate, also long-acting
-
Testosterone Propionate – Shorter-acting, needs more frequent dosing
-
Testosterone Undecanoate – Available as injection or oral, longer duration
-
Bioidentical Testosterone – Made from plants (like soy or yam), chemically identical to natural testosterone
Each type works at a different pace, so how often you take it depends on the form your doctor prescribes.
Ingredients in Different TRT Forms
-
Injectables: Testosterone dissolved in oils (e.g. sesame or cottonseed) for slow, steady release
-
Gels and Creams: Testosterone mixed with alcohol-based carriers for skin absorption
-
Patches: Use adhesives and enhancers to deliver testosterone through the skin
-
Pellets: Small implants placed under the skin, slowly releasing testosterone over months
-
Oral Capsules: Often combined with fatty acids to increase absorption in the digestive system
Synthetic vs. Bioidentical Testosterone: What’s the Difference?
-
Synthetic Testosterone: Lab-made and widely used in medical treatments. It mimics natural testosterone and is backed by decades of clinical use.
-
Bioidentical Testosterone: Sourced from plants and chemically matched to human testosterone. Popular for its “natural” label, though it works similarly to synthetic options.
