What are testosterone pellets (subcutaneous implants)?

Testosterone pellets are small solid implants, typically the size of a grain of rice, that contain bioidentical testosterone. During insertion, a provider makes a small incision (usually on the hip or buttock) and places the pellets in the subcutaneous tissue beneath the skin. The incision is closed with a single stitch or adhesive strip and heals within days.

Once inserted, the pellets release testosterone steadily into the bloodstream over a set period, usually between 3 and 6 months depending on the pellet formulation and individual metabolism. This steady-state delivery maintains relatively consistent hormone levels throughout the cycle, avoiding the peaks and troughs that can occur with weekly or bi-weekly injections. Unlike topical gels or creams, pellets do not transfer to partners through skin contact and do not require daily application or timing around showers.

Pellet implants differ fundamentally from other testosterone delivery methods. Injections deliver a bolus dose that gradually declines before the next shot, while gels provide daily dosing that requires compliance and careful timing. Pellets eliminate injection anxiety for some patients and reduce the need for frequent clinic visits, though insertion itself requires a minor office procedure. After each cycle ends, the pellets are naturally absorbed by the body, and new implants can be placed if treatment continues. A healthcare provider specializing in hormone therapy can assess whether pellets are appropriate for your needs and monitor hormone levels during treatment.
