Pellets vs Injections

Pellets and injections are both provider-reviewed delivery modalities for hormone optimization. Pellets release steadily over 3–6 months from a subcutaneous insertion. Injections deliver weekly (or split twice-weekly) doses the patient self-administers. The right modality is matched against biomarker behavior, dose-adjustment flexibility, lifestyle, and continuity preference.

Pellets
Injections
Release profile
Steady, multi-month
Pellets minimize day-to-day variability; injections allow tighter dose targeting.
Weekly peak-and-trough (smoothed by split dosing)
Cadence
Insertion every 3–6 months
Pellets reduce frequency; injections keep adjustment levers in the patient's hands.
Self-administered weekly or split
Dose adjustability
Fixed until next insertion
Injection cadence supports faster recalibration.
Adjustable at any cycle
Biomarker behavior
Smooth curves; harder mid-cycle adjustment
Both require the standardized biomarker panel on cadence.
Cleaner adjustment surface
Procedural overhead
In-office insertion
Home self-administration after training
Estradiol / hematocrit management
Slower to course-correct
Faster to course-correct
Lifestyle fit
Low-touch continuity
High control, weekly engagement
Choose Pellets

Choose pellets when low-touch continuity is the priority, when day-to-day variability has been a problem, and when the patient prefers fewer touchpoints between recalibrations.

Choose Injections

Choose injections when tight dose adjustability and faster recalibration matter, when the patient wants direct control of the cadence, or when biomarker behavior needs frequent fine-tuning.

Explore pathway

Educational. Final pathway selection is provider-reviewed via synchronous video consultation against your biomarkers, history, and goals.

Frequently asked

Are creams another option?

Yes. Transdermal testosterone cream is a third modality with its own absorption and biomarker profile, and is part of the same provider-reviewed decision. See the TRT Injection vs Cream comparison.

Can modalities be switched?

Yes — switching is provider-reviewed against biomarker response, lifestyle, and goals. It is not a self-directed change.
