Pellet therapy is a form of hormone replacement that delivers testosterone or estradiol through tiny, rice-grain-sized pellets implanted just beneath the skin. The pellets dissolve slowly over several months, releasing a steady stream of hormones into the bloodstream. It’s one of several ways to replace hormones that decline with menopause, andropause, or other conditions, but it stands apart because it requires no daily pills, weekly patches, or regular injections.
How the Procedure Works
The insertion takes about 10 to 15 minutes in a clinic or doctor’s office. A provider sterilizes the skin over the upper buttock or hip area and numbs it with a local anesthetic. Then they make a small puncture, no larger than a few millimeters, and use a thin, hollow instrument called a trocar to slide the pellets just under the skin. No stitches are needed. A small bandage covers the site, and you go home the same day.
The number and size of pellets depend on your hormone levels and symptoms. For women receiving testosterone pellets, typical doses range from 75 to 100 mg per insertion. Most patients return for a new round of pellets every three to five months, depending on how quickly their body metabolizes the hormones.
Why People Choose Pellets Over Other Methods
The main appeal is consistency. Patches can cause skin irritation and need replacing weekly. Creams require daily application and can transfer hormones to other people through skin contact. Injections produce a spike of hormones followed by a gradual drop before the next dose. Pellets avoid these peaks and valleys by releasing hormones at a relatively steady rate as they dissolve.
That steadiness appears to translate into better real-world results. In a comparison of women using pellet therapy versus a transdermal (skin-applied) hormone treatment, 89% of women on pellets reported that the therapy treated their symptoms, compared to 78% on the transdermal option. Women on pellets were also more likely to stick with treatment: 76% continued therapy versus 59% of those using the transdermal method. Part of this is probably convenience. When you only need to think about your hormones a few times a year instead of every day, it’s easier to stay consistent.
What Pellet Therapy Treats
Pellet therapy is used for the same symptoms that other forms of hormone replacement address. In women, that typically means hot flashes, night sweats, vaginal dryness, low libido, mood changes, sleep disruption, and brain fog associated with menopause or perimenopause. In men, it’s most often used for symptoms of low testosterone: fatigue, reduced muscle mass, low sex drive, and difficulty concentrating.
Some providers also use pellets for younger patients who’ve had their ovaries removed or who have conditions causing premature hormone decline. The approach is the same regardless of the reason: replace what the body is no longer producing in sufficient amounts.
Risks and Side Effects
Pellet therapy has a low complication rate based on data from over one million procedures. The most common issue is pellet extrusion, where one or more pellets work their way back out through the skin. This happens in fewer than 3% of men and fewer than 1% of women. In women specifically, extrusion is exceedingly rare, occurring in less than 0.1% of cases. When extrusion does happen, it tends to occur either within the first week or after about six weeks.
Infection at the insertion site (cellulitis) occurs in less than 1% of cases overall, and in less than 0.1% of women. No allergic reactions or keloid scarring were reported in the large dataset. Some people notice mild darkening of the skin at the insertion site, and a small amount of firmness under the skin can develop but typically resolves on its own before the next insertion.
Hormone-related side effects are also possible. These can include acne, hair thinning, facial hair growth in women, or mood changes if levels run too high. Because pellets can’t be easily removed once inserted, adjusting the dose mid-cycle isn’t straightforward the way it is with a cream or patch. If your levels come back higher than intended, you generally have to wait for the pellets to dissolve.
The Regulatory Landscape
Most hormone pellets used in the United States are compounded, meaning they’re custom-made by specialty pharmacies rather than manufactured by large pharmaceutical companies. This is an important distinction. Compounded pellets are not evaluated by the FDA for safety, effectiveness, or quality. The FDA has noted that while compounded hormone products can serve a legitimate medical need, they lack the same regulatory assurances as FDA-approved drugs.
This doesn’t mean compounded pellets are unsafe, but it does mean quality can vary between pharmacies. If you’re considering pellet therapy, the reputation and accreditation of the compounding pharmacy matters. Many clinics work with pharmacies that follow strict manufacturing standards, but this isn’t universally guaranteed.
Cost and Insurance
Pellet therapy costs roughly $1,536 per year on average, though this varies by provider, location, and whether you’re receiving testosterone alone or a combination of hormones. With insertions needed every three to five months, that breaks down to a few hundred dollars per visit. Most insurance plans do not cover compounded hormone pellets, so this is typically an out-of-pocket expense. Some clinics offer payment plans or membership pricing to offset the cost.
For comparison, generic oral hormones or patches covered by insurance can cost significantly less. The trade-off is convenience and the steady hormone delivery that pellets provide. Whether that premium is worth it depends on how well other methods have worked for you and how much the convenience factor matters in your daily life.
