Of the men prescribed topical testosterone, only about 15% are still using it a year later. Daily application, transference worries, and inconsistent absorption grind men down until they stop, usually on the exact method they were handed first.
That staying-power gap is where this comparison starts, because a method only helps while you’re actually using it.
This guide puts injections, gel, cream, and pellets side by side across six dimensions, cost, convenience, testosterone stability, side effects, who each suits, and real-world adherence, and ends with a framework to match one to how you actually live, not just what your labs say.
TRT delivery methods compared at a glance.
| Injections (IM/SubQ) | Gel | Cream (compounded) | Pellets | |
| Monthly cost | ~$40–100 (generic) | ~$200–400 brand / ~$150–300 generic | ~$60–150 | ~$2,000–4,800/yr ($500–1,000 per insertion, 2–4×/yr) |
| Dosing & convenience | Self-inject 1–2×/week | Apply daily | Apply daily | Implanted every 3–6 months; hands-off |
| Testosterone stability | Steady 7–14 days, but peak-and-trough | Daily steady-state | Daily steady-state | Long steady, then tapers |
| Main side-effect concern | Fastest hematocrit rise; injection-site soreness | Transference to others; ~5–10% absorb poorly | Same as gel; scrotal use raises DHT | Highest erythrocytosis; extrusion/infection; dose can’t be changed |
| Best for | Cost, control, easy dose changes | Needle-averse, want daily steadiness | Needle-averse, want a cheaper topical | Hate maintenance, travel, compliance struggles |
| Real-world adherence | Higher persistence | Low, ~15% at 12 months | Low (topical pattern) | Hands-off, but locked in 3–6 months |
Patches, nasal gels, and oral testosterone exist too, but for most men the real decision comes down to these four.
How each TRT method works, and how stable your levels stay
Every method delivers the same hormone. What differs is the curve.
- Injections release testosterone from a depot over days, steady for roughly 7–14 days, but with a peak after the shot and a trough before the next one. How wide that swing feels depends mostly on frequency; splitting a weekly dose into twice-weekly (or smaller, more frequent) injections flattens it.
- Gel and cream absorb through the skin for daily steady-state levels, no peaks, no troughs. The catch is variability: roughly 5–10% of men are “absorption non-responders” whose serum testosterone barely moves despite compliant daily use, which only shows up on labs at 4–6 weeks. Cream applied to scrotal skin absorbs far more and sharply raises DHT, sometimes useful, sometimes not.
- Pellets sit under the skin and release testosterone steadily for months, then taper toward the end of the cycle. The trade-off is control: once they’re in, the dose can’t be changed until they dissolve.
TRT method costs compared: injections vs. gel vs. cream vs. pellets
Cost tracks convenience almost perfectly, the less you have to do, the more you pay.
- Injections are the cheapest by a wide margin: generic testosterone cypionate runs roughly $40–100/month, and a single 10 mL vial can be $20–50.
- Compounded cream is the value topical at about $60–150/month. Brand-name gels like AndroGel run $200–400/month, with generic gels around $150–300.
- Pellets are front-loaded, $500–1,000 per insertion, two to four times a year, landing around $2,000–4,800 annually.

Side effects by method, what’s specific to each
The core risks of testosterone are shared across methods. What changes is which one hits hardest:
- Injections: the fastest rise in hematocrit (the proportion of red blood cells in your blood, which thickens it), because post-injection peaks stimulate red-cell production more than steady levels do, plus injection-site soreness.
- Gel and cream: transference is the signature risk, testosterone can transfer to a partner or child through skin contact, alongside skin irritation and that absorption variability.
- Pellets: the highest erythrocytosis rates of any method, plus insertion-site risks (infection, and spontaneous extrusion, where a pellet works its way back out), and no way to dial the dose back if a side effect appears.
Notice the pattern; the method that keeps levels steadiest (gel) tends to be gentlest on hematocrit, while the peak-driven (injections) and long-depot (pellets) methods push it hardest.
Which method do men actually stick with? The adherence gap nobody mentions
Topical testosterone has poor staying power in the real world: only about 34.7% of men are still using it at 6 months, and just 15.4% at 12 months. Injections show meaningfully better persistence, and pellets are hands-off by design, nothing to remember for months at a time.
Satisfaction, interestingly, is high and similar across methods once men stay on them, roughly 73% for injections, 68% for gels, and 70% for pellets in one academic survey. Gels work well for the men who keep using them; the daily friction of a topical is what ends the therapy for the rest, usually before the medicine ever gets a fair test.
So if you know you’re inconsistent with daily routines, treat that as a real input to your choice and lean toward a method that doesn’t depend on daily discipline.
Which TRT method is right for you?
Rank your top priority, then follow it:
- Cost is the deciding factor: injections. Nothing else is close, and levels are reliable.
- You can’t stand needles: gel or compounded cream, going in clear-eyed about transference precautions and the chance you’re a low absorber.
- You travel constantly or know you won’t keep a daily routine: pellets. You trade dose flexibility and upfront cost for not having to think about it.
- You want to fine-tune your dose as labs evolve: injections. The only method you can adjust week to week.
- You have young kids or a pregnant partner at home: avoid gel and cream unless you can guarantee strict application-and-cover discipline; injections and pellets sidestep transference entirely.
- Your hematocrit already runs high: gel is gentlest; if you prefer injections, more frequent smaller doses beat one weekly shot.
Most men do well starting on injections, cheapest, most flexible, easiest to adjust, and switching later if it doesn’t fit. The wrong move is letting whatever gets prescribed first become permanent by default.
The method that’s right for you depends on your labs, your side-effect risks, and, honestly, your habits, which is exactly why it shouldn’t be a coin flip or whatever the first prescription happened to be.
Conclusion
On paper, these four methods are more alike than different, same hormone, similar satisfaction once men stay on them. The real gap is sustainability: a cost you can carry, a routine you’ll actually keep, and side effects you can live with. That’s why the adherence numbers matter more than the pharmacology charts.
Work from how you actually live, your budget, your tolerance for needles or daily upkeep, your household, your labs, and choose the method from there. Get that match right and it mostly disappears into the background, which is exactly where it belongs while the results move to the front.
Action TRT chooses the delivery method with you based on a full workup and your real life, tracks how your levels and symptoms respond, and switches you if the first choice isn’t sticking. If a method isn’t covered by insurance, HSA/FSA dollars can cover it pre-tax.
