TRT Delivery Methods: Injections vs Gels vs Pellets
How the way you take testosterone changes the side-effect profile, convenience, and monitoring. An honest comparison.

The delivery method is not a cosmetic choice — it changes which side effects are more likely, how steady your levels are, and what monitoring looks like.
Injections (intramuscular or subcutaneous) are the most common and cost-effective. They can produce a peak-and-trough pattern that some men feel as mood or energy swings toward the end of a cycle, and they carry a higher incidence of elevated hematocrit. Subcutaneous injections smooth this out somewhat.
Topical gels provide steadier levels but carry a risk of transdermal transfer to others through skin contact while wet. Patches can cause local skin irritation. Pellets, implanted every few months, avoid daily compliance but can cause local complications like infection or extrusion.
Your provider recommends a method based on your labs, lifestyle, and risk profile — not a default. See the TRT program page for what is included.
