Once you’ve been diagnosed with low testosterone and decided to pursue treatment, the next question is practical: how is it actually delivered? The method matters more than most men expect. It affects how often you need treatment, how stable your levels are, and what daily life on therapy looks like.
Here’s the breakdown.
The Main Types of TRT
Testosterone replacement therapy comes in several delivery forms. The AUA guidelines note that each has a distinct pharmacokinetic profile — they differ in how testosterone is absorbed, how levels rise and fall, and how long each dose lasts.
The right choice depends on your lifestyle, your preference for how often you want to think about this, how your body responds, and what your physician recommends based on your labs.
Testosterone Injections
Injectable testosterone is one of the most commonly used forms. It’s typically given every one to two weeks, either at the clinic or self-administered at home.
Advantages:
- Reliable absorption and predictable dosing
- Cost-effective compared to other methods
- Easy to adjust dose based on lab results
- No risk of transfer to partners or children
Considerations:
- Testosterone levels peak shortly after injection and drop before the next dose. Some men notice mood or energy dips with longer intervals
- Requires comfort with injections (or clinic visits)
- More frequent dosing (weekly rather than bi-weekly) smooths out level fluctuations
Testosterone Gels and Creams
Topical formulations are applied daily to the shoulders, upper arms, or abdomen. Testosterone absorbs through the skin into the bloodstream.
Advantages:
- Maintains relatively stable testosterone levels (daily application prevents peaks and troughs)
- Easy to use and non-invasive
- Dose is adjustable
Considerations:
- Risk of transfer to partners or children through skin contact — requires precautions around application timing and contact
- Daily application required — adherence matters
- Absorption varies between individuals; some men don’t absorb topicals well
- Higher cost than injections
Testosterone Pellets
Pellets are small implants inserted under the skin — typically near the hip or buttocks — in a brief in-office procedure. They dissolve over three to six months, releasing testosterone gradually.
Advantages:
- Very consistent testosterone levels — no daily or weekly dosing
- Nothing to remember between insertions
- No risk of partner transfer
Considerations:
- Dose cannot be adjusted once implanted — you’re committed until the pellets dissolve
- Minor in-office procedure required every 3-6 months
- Uncommon but possible side effects include pellet extrusion or infection at the insertion site
- Higher upfront cost per insertion cycle
Oral Testosterone
FDA-approved oral formulations are now available. They’re taken twice daily with food — an option for men who want to avoid injections and topicals entirely.
Considerations:
- Twice-daily dosing required for consistent levels
- Absorption depends on fat intake at meals
- Newer option with less long-term data compared to injections or gels
How to Choose
There’s no universally best method. Morgentaler et al. have observed that patient preference and adherence drive real-world outcomes — the best form of TRT is the one you’ll actually use consistently.
Questions that help narrow it down:
- Do you prefer daily treatment or infrequent dosing?
- Are you comfortable with self-injection or clinic visits?
- Do you have young children or a partner with concerns about transfer?
- How important is level stability versus dose flexibility?
Questions to Ask Your Provider
- Which delivery method best fits my lifestyle and health profile?
- How do we adjust dosing if levels are off?
- How often will I need follow-up labs?
- What happens if I want to stop treatment?
