Pellet Hormone Therapy vs. Injections: Which Is Better for You?

One of the most common questions patients ask when beginning hormone replacement therapy is about delivery methods. The two most popular options for testosterone (and estradiol, for women) are injectable therapy and subcutaneous pellets. Both can achieve adequate hormonal supplementation — but they differ substantially in their pharmacokinetics, flexibility, cost, and risk profiles. Understanding these differences helps you make an informed decision with your provider.

How Pellets Work

Hormone pellets are small, cylindrical implants — slightly larger than a grain of rice — made from compounded bioidentical testosterone (for men) or estradiol or testosterone (for women). They are inserted under the skin, typically in the upper buttock or hip area, through a minor in-office procedure under local anesthetic. Once implanted, they release hormone gradually as the pellet slowly dissolves over 3–6 months. Men typically require insertion every 4–5 months; women every 3–4 months.

Advantages of Pellets

The primary appeal of pellets is convenience — no weekly injections, no daily gel application. Some patients find the consistent, gradually declining hormone release more natural-feeling than the peaks and troughs of weekly injections. For patients who travel frequently or simply prefer minimal maintenance, this convenience is significant.

Disadvantages and Risks of Pellets

The most significant disadvantage of pellets is irreversibility within the implantation period. If a pellet is overdosed — and overdosing is common due to the difficulty of precisely predicting each patient’s absorption rate — the hormone levels cannot be reduced until the pellet dissolves naturally, which can take months. Overdosed pellets frequently cause polycythemia (elevated hematocrit), excessive estradiol elevation, mood disturbances, and in women, irreversible clitoromegaly (permanent clitoral enlargement from excess testosterone). These side effects cannot simply be dose-adjusted — the patient must wait them out.

Pellets are also typically more expensive than injectable therapy and are not covered by most insurance plans. The insertion procedure carries a small risk of infection, extrusion, or fibrosis.

Why Multigen Wellness Primarily Uses Injectables

At Multigen Wellness, we primarily use injectable testosterone for our male patients because it offers precise, adjustable dosing — a critical feature in a therapy that requires ongoing titration based on lab values and symptom response. If a dose needs adjustment, it is immediate with injectables; with pellets, you wait months. Twice-weekly subcutaneous injections with a small insulin needle are virtually painless and easy to perform at home. For patients who strongly prefer pellets, we can facilitate appropriate referrals — but we believe the flexibility and adjustability of injectables produces superior long-term outcomes for most patients.
