A patient called the office about ten days after her first pellet insertion. Mild bruising at the site, a small lump under the skin, energy already a little better, sleep markedly better — and she wanted to know whether any of that was a problem. None of it was. That conversation, in some version, happens nearly every week in my practice. The patients who do best with pellet therapy are the ones who know in advance what is expected and what is not, because the difference between a normal post-insertion course and an actual problem is usually obvious once you have a frame of reference.
This article is the frame of reference. I will walk through what is expected, what warrants a phone call, and the small number of things that warrant being seen the same day. I will also be candid about who should not have pellets at all.
What pellets actually do once they are in
A Biote pellet is a compressed crystalline form of bioidentical testosterone (with estradiol added in some women's protocols) inserted into the subcutaneous fat of the upper outer hip. Once placed, the pellet releases hormone slowly as cardiac output rises and falls — meaning more is released when you exercise, less when you rest. That cardiac-output dependency is part of why pellets feel different than injections or creams. It mimics a more physiologic release pattern than the spike-and-trough of weekly injections.
Pellets dissolve over three to four months in women and four to five months in men. There is no removal. The body absorbs the carrier and the hormone is metabolized through the same pathways as endogenous testosterone. That basic mechanism — slow, exercise-responsive release of an actual bioidentical molecule — is what makes pellet therapy a reasonable Biote pellet therapy option for the right patient. It is also what produces the predictable side-effect profile I want you to understand before you sit on my procedure table.
What is normal in the first two weeks
The insertion site itself takes a couple of weeks to settle. Most of what patients call to ask about falls in this window, and almost all of it is expected.
Bruising at the insertion site. I use a small trocar to place the pellets through a single incision under the skin. There are small subcutaneous vessels in that area, and a bruise the size of a half-dollar is normal. Some patients bruise more than others — if you are on aspirin, fish oil, or a daily glass of wine, expect more. The bruise will go through the usual color progression and clear in seven to fourteen days.
A palpable lump or firmness. You can usually feel the pellets under the skin for the first one to two weeks — they feel like small grains of rice. Some patients also notice a thumb-sized area of firmness around the site as the body lays down a little fibrotic tissue around the implant; that softens over a few weeks.
Mild soreness with movement. Sitting cross-legged, certain yoga positions, or sleeping on the implant side may be uncomfortable for a few days. Ibuprofen is fine if you are not on a blood thinner.
Slight pink or clear drainage on the dressing in the first 24 hours. Expected. Heavy bleeding through the dressing is not — that is a phone call.
An early energy bump in the first ten to fourteen days. Some patients feel it because hormone release from a freshly placed pellet is highest in the first week. The dose will normalize as the pellet equilibrates.
What is normal in the first one to three months — and what is the dose talking
Once the insertion site has healed, the side effects you may notice are the dose itself talking. Some of this is expected and self-limiting. Some of it tells me I dosed you a little high.
Acne or oily skin. Common in the first month, especially in women new to testosterone. Usually settles. If it persists past month two or is significant, your dose was too high for your sebaceous-gland sensitivity and we will go down at the next insertion.
Mild facial hair changes. Slow, progressive in some women. Reversible with dose reduction. I screen for this every visit.
Fluid retention or breast tenderness. Usually a sign that aromatization is high — your body is converting some of the testosterone to estradiol. In men this can happen at higher doses. Check labs at six weeks and adjust.
Mood lift, then slight irritability around weeks six to ten. Normal arc. The peak hormone exposure happens in the first six weeks; if you feel slightly more reactive in week eight, the level is coming down toward steady state, not up.
Increased libido and morning erections. Expected and welcome — but if libido becomes uncomfortably high, the dose was too high. Tell me.
Slight scalp hair shedding around month two to three. This catches women off guard. It is usually transient and related to the hormonal shift, not androgenic alopecia. If you have a strong family history of pattern hair loss, we discuss this in detail before insertion.
These are dose-dependent and individual. The whole reason I take labs and a symptom inventory at six weeks after the first insertion is so the second insertion can be calibrated to the patient sitting in front of me, not the average patient.
What is not normal — call the office
Not sure where to start?
The Start Here pathway walks you through the most common entry points and helps you decide which consultation type is the right fit. Five minutes of self-assessment can save you a wrong-direction conversation.
A short list, and worth memorizing.
Spreading redness, warmth, or streaking out from the insertion site beyond day three. This is how a site infection looks. Cellulitis at a pellet site is uncommon but not rare, and it needs antibiotics promptly. Same-day evaluation.
A pellet visibly extruding through the skin. Pellets should stay subcutaneous. If you can see one working its way out of the incision, this is pellet extrusion and needs to be addressed in the office. We remove the extruding pellet, redress the site, and figure out what contributed — usually early heavy lifting, thin subcutaneous fat at the site, or a dressing issue. Fixable; do not ignore it.
Persistent heavy bleeding through the dressing in the first 24 hours. Apply firm pressure for ten minutes and call. Almost always settles, but I want to know.
A painful, expanding fluid collection at the site. A hematoma can develop, particularly in patients on blood thinners. Call.
Sudden severe pelvic or chest symptoms. New chest pain, severe leg swelling, severe headache with visual changes, or sudden shortness of breath are emergency-room visits, not next-week phone calls. My ER and cardiac ICU years make me direct about this. Hormone therapy carries a small absolute risk of clotting events — small enough that the benefit-to-risk math favors treatment for most appropriate candidates, but not zero, and you should know how to recognize it.
Symptoms suggesting your dose is meaningfully off. Severe acne, persistent fluid retention, mood instability worse than baseline, voice changes in women, significant scalp hair loss. These tell me the calibration is wrong and we need to change the next insertion.
How I evaluate side-effect calls before insertion #2
When patients call with a side effect concern between the first and second pellet, I am running through a short clinical algorithm. It is the same one I use whether you are at the Columbus location or the Warner Robins location.
First: is this an insertion-site issue or a systemic-dose issue? Site issues usually appear in the first two weeks and stay localized. Systemic-dose issues usually appear at three to six weeks and are body-wide.
Second: what do the six-week labs show? Total testosterone, free testosterone, estradiol, SHBG, hematocrit. The labs tell me whether the level is above optimal, optimal, or below optimal, and whether aromatization is excessive. The numbers and your symptom report together drive the next dose.
Third: what was the patient doing in the first week post-insertion? Heavy deadlifts, hot yoga, sitting on the site for long periods — these contribute to extrusion risk and to bruising severity. The history matters.
Fourth: are there contributing factors I missed at the workup? Subclinical thyroid issues, untreated insulin resistance, sleep apnea, alcohol use shifts. Any of these can mimic dose-related side effects. The patient who feels worse on a perfectly dosed pellet usually has an adjacent issue we have not addressed.
This is why comprehensive lab work on the front end matters — the cleaner the workup before the first pellet, the less ambiguous the side-effect interpretation after.
Who I will not insert pellets in
Side effects are easier to manage when the right patient is in the chair. There are a few categories where pellets are not the right tool, and I will tell you so directly at the consultation rather than insert and hope.
- Active or recent hormone-sensitive cancer
- Untreated severe sleep apnea (testosterone can worsen apnea before the apnea is controlled)
- Hematocrit already at or above the upper reference range
- Pregnancy or active attempts to conceive in women
- A patient who wants the option to stop quickly — pellets cannot be removed once placed, so injections or creams are a better starting point if reversibility is a priority
- A patient whose primary issue is not actually hormonal — usually identified on the lab review
For women, I also do not insert pellets without addressing progesterone if you have a uterus. That is a non-negotiable in my practice, and I would rather have the conversation about it before you book than after.
If men's testosterone replacement is what you are evaluating, the same logic applies — pellets are one delivery method, not the only one, and we will pick the form that fits your physiology and your reversibility preferences.
A concrete next step
If you have a pellet in and something is bothering you — call the office. Describe what you are noticing, when it started, and what makes it better or worse. The front desk routes pellet site concerns to me directly. Most calls resolve with a short conversation; the small number that need to be seen get seen the same day.
If you are weighing pellets for the first time, the right next step is the lab and history visit. Bring any prior hormone labs, your medication and supplement list, and a written list of your top three goals. Six weeks after insertion we recheck labs and your symptom inventory, and the second pellet gets calibrated to what we actually saw. That single follow-up loop is what separates a pellet patient who does well from one who does not.
Use the hormone health assessment for a structured starting point, or book a consultation directly. We start with the data.
