What to Do After Pellet Insertion for a Smooth Recovery

Keeping your activity level low and protecting the insertion site during the first week are the two most impactful things you can do after hormone pellet implantation. A large analysis of over one million pellet procedures found an overall complication rate below one percent, and increased physical activity in the first week was one of only two factors that significantly predicted problems like infection and pellet extrusion. The recovery itself is straightforward, but the details matter more than most patients expect.

Why the First Week Matters So Much

Hormone pellets are placed in a small pocket of subcutaneous fat, typically in the upper buttock or lower abdomen. The incision is small, but the tissue around the pellets needs time to form a capsule that holds them in place. When you move vigorously before that capsule develops, the pellets can shift toward the surface and eventually push through the skin, a complication called extrusion.

Research on this is consistent. A study of nearly a thousand testosterone implant procedures found that the rate of adverse events, especially extrusion, was significantly tied to higher levels of physical activity at work in the days following implantation.¹ A separate analysis covering over a million procedures confirmed that increased activity in the first week after pellet insertion, along with a higher number of inserted pellets, were the only patient-related factors that significantly predicted complications like cellulitis and extrusion.²

For the first five to seven days, you should avoid lower-body exercise, heavy lifting, prolonged sitting on hard surfaces, and anything that creates repeated pressure or friction over the insertion site. Walking gently is usually fine. Running, cycling, squatting, lunging, and similar activities are not. If your job involves physical labor, plan for lighter duties during that window. The data linking occupational activity to extrusion is strong enough that some providers specifically ask about your work duties before scheduling the procedure.¹

Caring for the Incision Site

The insertion site is a small wound, typically closed with adhesive strips or a single stitch. It needs to stay clean and dry while it heals. Most clinics advise keeping the original dressing on for at least 24 to 48 hours and avoiding submerging the area in water for about a week. Brief showers are generally permitted after the first day or two, but baths, swimming pools, and hot tubs introduce bacteria into a healing wound and should be avoided until the incision has fully closed.

The connection between following post-procedure instructions and avoiding complications is more direct than you might assume. A retrospective safety analysis of testosterone pellet therapy found that none of the patients who complied with post-implant care instructions experienced infection or pellet extrusion.³ That is a striking result. It suggests that the instructions you get from your provider are not just cautious advice but genuinely protective. If you are told to leave the dressing alone for 48 hours, leave it alone.

How Dressings Reduce Extrusion

This is one of the more underappreciated details in pellet therapy aftercare. The type of dressing used after insertion makes a measurable difference. In one large clinical dataset, extrusion rates in men dropped by half after clinics switched from simple gauze-and-tape dressings to a semipermeable membrane dressing. Before the switch, extrusions were occurring at a rate of about four percent; afterward, that number fell significantly.²

A semipermeable membrane dressing is the kind of clear, waterproof adhesive film you may recognize from surgical or IV sites. It holds the incision closed, limits bacterial entry, and keeps the pellets from migrating toward the surface during the critical early healing window. If your clinic sends you home with gauze only, it may be worth asking whether a membrane-style dressing is available. Some patients apply one themselves over the gauze after the initial dressing change, though you should confirm with your provider before doing so.

Understanding Extrusion

Extrusion is the most common complication of pellet therapy, and knowing what it looks like helps you catch it early. An extruding pellet works its way toward the skin surface and eventually pushes through. You may notice a small hard lump near the incision, increasing tenderness, or the pellet itself becoming visible or palpable just under the skin. Sometimes the pellet comes out on its own; other times it partially emerges and stalls, which can lead to irritation or low-grade infection.

In men, extrusions tend to follow one of two patterns. Some happen early, within four to seven days of insertion, usually related to physical activity or wound disruption. Others happen much later, more than 60 days after the procedure, and in those cases the cause is less clear. The average time from procedure to first extrusion in one large dataset was about 65 days, with a range of 4 to 150 days. About two-thirds of extrusions involved just one pellet, and the rest involved two or more.² In women, extrusions are rare, occurring in fewer than one in a thousand procedures, and most happen after six weeks.

There is also a link between local infection and subsequent extrusion. A controlled study found that among men who developed an infection at the site requiring antibiotics, 60 percent went on to experience an extrusion afterward.⁴ This makes wound care and infection prevention all the more important in those first days.

Does the Insertion Location Matter

It does, and the evidence on this is clear enough to be worth knowing. A randomized trial compared pellet extrusion rates between the hip and the lower abdominal wall and found a significantly higher rate of extrusion from the hip site, roughly 12 percent versus 5 percent for the abdominal site.⁵ The hip is subject to more mechanical stress from sitting, walking, and bending, which likely accounts for the difference. If you have a choice and your provider offers both sites, the lower abdomen tends to have fewer complications. Many clinics now default to the upper gluteal or flank area, which balances comfort with stability.

The same study looked at whether the angle or geometry of the insertion track affected outcomes and found no meaningful difference. What did matter, interestingly, was operator experience. One provider in the study had significantly fewer adverse events than others, reinforcing that the skill of the person placing the pellets is a real variable in your outcome.⁵

What Your Hormones Are Doing After Insertion

Understanding the hormone release pattern helps you set realistic expectations about when you will start feeling different and when you might feel a dip. Testosterone pellets do not deliver a steady, flat dose from day one. Levels fluctuate during the first two weeks, then settle into a more predictable decline over the following months.⁶

Testosterone levels typically peak during the first month after implantation. In pharmacokinetic studies, those levels then gradually declined but remained in the physiological range for four to six months depending on the dose used.⁷ Each 200-milligram pellet releases roughly 1.5 milligrams of testosterone per day, and the release follows a predictable pattern throughout the pellet’s effective life.

What this means for you is that you may notice an energy boost or mood improvement within the first few weeks as levels climb toward their peak. Some people feel a surge in the first two weeks as levels fluctuate; others notice a more gradual benefit. Either is normal. You should not panic if you feel somewhat “off” during the first week or two, as levels are still stabilizing. By the end of the first month, most patients are at or near peak benefit.

Body composition affects the timeline. Men with a higher body mass index tend to reach lower peak testosterone levels with a slower rate of decline compared to leaner men receiving the same number of pellets, though both groups reached the lower threshold of effective levels at roughly the same point, around 100 days out.⁸

When to Contact Your Provider

Mild bruising, slight soreness, and a small amount of swelling around the insertion site are all normal in the first few days. These should improve steadily. You should reach out to your provider if you notice any of the following:

Increasing redness or warmth: Redness that is spreading rather than fading could indicate cellulitis or local infection.
Pus or unusual discharge: A small amount of clear or slightly blood-tinged fluid is common initially, but thick or discolored discharge is not.
A hard lump near the incision that grows or becomes painful: This may signal a pellet migrating toward the surface.
Fever: A systemic sign of infection that warrants prompt evaluation.
A pellet visible at the skin surface: If a pellet has partially extruded, your provider can remove it cleanly and assess whether the remaining pellets are intact.

Subcutaneous nodules can form at the insertion site and are usually benign, especially if they are not growing or painful. These are part of the tissue response to the foreign material and often resolve over time. Other possible skin-level effects include scarring and fibrosis, particularly after multiple insertions at the same location.⁹

Side Effects to Expect, Especially for Women

Beyond the insertion site itself, the hormone changes from pellet therapy can produce side effects, especially when testosterone is the active hormone. In women, the most commonly reported side effects are increased facial hair and acne. One study of women receiving testosterone pellets for menopausal symptoms found facial hair in a substantial number of patients, with acne as the second most frequent complaint. The typical management approach was a dose reduction, and women who still had symptoms after that were often started on spironolactone, a medication that counteracts some androgenic effects on the skin.¹⁰

For women receiving lower-dose testosterone pellets for low libido, a long-term study found only mild side effects. About five percent of women receiving 75-milligram pellets reported mild facial hair growth, and roughly ten percent reported vaginal bleeding. No clinically significant changes in blood pressure or hematocrit were observed, and no patients required blood removal (phlebotomy) to manage thickening blood.¹¹ This is reassuring for women on long-term pellet therapy, as elevated red blood cell counts are a known concern with testosterone use in men.

If you are a woman receiving estradiol pellets and you still have a uterus, your provider should be prescribing a progestogen alongside the estrogen. Unopposed estrogen therapy, meaning estrogen without progesterone, is associated with an increased risk of abnormal uterine lining changes at all doses and durations between one and three years.¹² If your provider has not discussed this with you, bring it up. It is a standard part of safe estrogen therapy for anyone with an intact uterus.

When to Schedule Your Next Insertion

One of the most common mistakes patients make is waiting too long to come back for their next round of pellets. Pharmacokinetic data suggest that reimplantation should occur at roughly 100 to 120 days after the prior insertion.⁸ That is about three and a half to four months. Many patients, feeling good at the two-month mark, assume the pellets will last six months and do not schedule a follow-up until they start feeling symptoms return. By that point, levels may have dropped well below the therapeutic range.

Your provider may recommend blood work at the one-month mark to check your peak levels, and again at three to four months to catch where your levels are as the pellets wind down. These results help your provider calibrate the dose and number of pellets for your next insertion. If you felt great at first but started feeling sluggish or symptomatic toward the end, that timing information is valuable for optimizing future cycles.

The continuation rate for pellet therapy is high. In the large dataset covering over a million procedures, 93 percent of patients continued past two insertions, which speaks to both effectiveness and tolerability.²

Rotating the Insertion Site

If you are on long-term pellet therapy, the question of what happens to the insertion site over repeated procedures is worth thinking about. Repeated insertions into exactly the same spot can cause local fibrosis, meaning the tissue becomes tougher and more scarred over time. This can make future insertions more difficult and may affect how well the pellets absorb. Scarring, subcutaneous nodules, and changes in skin texture at the site are all documented consequences of repeated use of the same location.⁹

Most experienced providers rotate the site slightly with each insertion, alternating between left and right sides or shifting the position within the same general area. You can help by noting which side was used at your last visit. Some patients keep a simple log of left versus right and the approximate location, which makes it easy to remind the clinic at your next appointment. This is a small habit that pays off over years of therapy.

Occasional skin reactions beyond scarring have also been reported, including localized dermatitis at the insertion site. These are uncommon but worth mentioning to your provider if you notice persistent itching, rash, or unusual skin changes around an old insertion site. In rare cases, a contact or inflammatory reaction to the pellet material itself has been described, though the pellets are made of compressed crystalline hormone without binders or foreign materials, which keeps such reactions rare.

What Research Has Not Settled

Researchers have tried several approaches to bring extrusion rates even lower, and the results have been mixed. One randomized trial tested whether soaking pellets in antiseptic solution before insertion would reduce extrusions and found no benefit at all; the extrusion rate was essentially the same in both groups.⁴ Another trial tested whether soaking pellets in antibiotic solution would help and found a 20 percent reduction in the odds of extrusion, but the difference was not statistically significant.¹³ So while provider technique, site selection, dressing type, and patient activity level have all shown clear effects, pre-treatment of the pellets themselves has not proven helpful in a controlled setting.

Late extrusions, those happening two months or more after insertion, remain poorly understood. In one large dataset, patients with late extrusions did not differ from other patients in age, activity level, weight, or body fat percentage.² Something is driving these late extrusions, but we do not yet know what. If you experience one, it does not necessarily mean you did anything wrong or that future insertions will have the same problem.
