Testosterone Injection vs Gel vs Pellets: Which TRT Delivery Method Is Right for You?
TRT comes in multiple forms—injections, gels, creams, patches, and pellets. Each has trade-offs in cost, convenience, and how steady your testosterone levels stay. Here's how to choose.
Quick Comparison
| Method | Frequency | T Levels | Cost |
|---|---|---|---|
| Injections | Weekly/Bi-weekly | Peak & trough | $ |
| Gels/Creams | Daily | Stable | $$ |
| Patches | Daily | Stable | $$ |
| Pellets | Every 3-6 months | Most stable | $$$ |
Testosterone Injections
Injections are the most common and cost-effective TRT method. They're administered intramuscularly (IM) into the glute or thigh, or subcutaneously (SubQ) into belly fat.
Pros
- ✓ Most affordable option
- ✓ Highest T levels achievable
- ✓ Easy to adjust dosing
- ✓ Often covered by insurance
- ✓ Can self-administer at home
- ✓ No risk of transfer to others
Cons
- ✗ Peak/trough cycling (mood swings)
- ✗ Requires needles
- ✗ Weekly or bi-weekly commitment
- ✗ Higher hematocrit increase risk
- ✗ Injection site soreness
Common Injection Types
- Testosterone Cypionate: Most common in US. Half-life ~8 days. Weekly or bi-weekly dosing.
- Testosterone Enanthate: Very similar to cypionate. Half-life ~4.5 days. Weekly dosing preferred.
- Testosterone Propionate: Shorter half-life (~2 days). Requires more frequent injection. Less common.
💡 The Peak/Trough Issue
With bi-weekly injections, T levels spike 2-5 days post-injection then drop back to baseline by day 13-14. Some men feel great after injection but sluggish by the end. Weekly injections create more stable levels and are increasingly preferred.
Testosterone Gels & Creams
Topical testosterone is applied daily to the skin (shoulders, arms, abdomen, or scrotum for creams). It absorbs through the skin into the bloodstream.
Pros
- ✓ Stable, consistent T levels
- ✓ Mimics natural T rhythm
- ✓ No needles
- ✓ Easy to adjust dose
- ✓ Lower hematocrit risk vs injections
- ✓ Less estrogen conversion
Cons
- ✗ Daily application required
- ✗ Transfer risk to partners/children
- ✗ Variable absorption (person to person)
- ✗ More expensive than injections
- ✗ Can be messy
- ✗ May affect body hair at site
⚠️ Transfer Warning
Testosterone can transfer through skin-to-skin contact or clothing. Women and children should not be exposed. Wash hands thoroughly after application, let it dry completely, and cover the application site with clothing before contact with others.
Testosterone Patches
Patches are applied to the skin daily (rotating sites: back, thigh, abdomen, upper arm). They provide steady T release over 24 hours.
Pros
- ✓ Stable T levels
- ✓ Once-daily application
- ✓ Less mess than gels
- ✓ No needles
Cons
- ✗ Skin irritation/rash common
- ✗ May not adhere well (sweat, body hair)
- ✗ Visible on skin
- ✗ Limited dosing flexibility
- ✗ More expensive than injections
Patches are less popular than gels or injections due to skin irritation issues and adherence problems. Many men who try patches switch to other methods.
Testosterone Pellets
Pellets are small, rice-sized implants inserted under the skin (usually in the hip area) during a minor in-office procedure. They release testosterone steadily for 3-6 months.
Pros
- ✓ Most stable T levels
- ✓ Only 2-4 procedures/year
- ✓ Maximum convenience
- ✓ No daily/weekly routine
- ✓ No transfer risk
- ✓ "Set it and forget it"
Cons
- ✗ Most expensive option
- ✗ Requires minor surgery
- ✗ Can't adjust dose once implanted
- ✗ Infection/extrusion risk (rare)
- ✗ Absorption rate varies
- ✗ Rarely covered by insurance
💡 The Dosing Problem with Pellets
Once pellets are in, they're in. If you have side effects or levels are too high/low, you have to wait 3+ months or have them surgically removed. With injections or gels, dosing can be adjusted immediately.

How to Choose Your Method
Choose Injections If:
You want the most affordable option, don't mind needles, and are comfortable with a weekly/bi-weekly routine.
Choose Gels/Creams If:
You want stable levels, hate needles, don't mind daily application, and can ensure no transfer to others.
Choose Pellets If:
Convenience is paramount, you don't mind the higher cost, and you've already dialed in your ideal dose with another method.
Satisfaction Rates: They're All Similar
A study of 382 men on TRT found satisfaction rates were similar across all methods:
- •Injections: 72.5% satisfied
- •Pellets: 69.8% satisfied
- •Gels: 68.4% satisfied
The bottom line: all methods work. The "best" one is whichever fits your lifestyle, budget, and comfort level.
Key Takeaways
- 1. Injections are cheapest and most effective at raising T, but create peaks/troughs
- 2. Gels/creams provide the most stable levels but require daily use and have transfer risk
- 3. Pellets are most convenient (2-4 times/year) but most expensive and least adjustable
- 4. Satisfaction is similar across all methods (~70%)
- 5. You can switch methods if one doesn't work for your lifestyle
- 6. Start with injections or gels to dial in your dose before considering pellets
