BioTE is a branded method of bioidentical hormone replacement therapy (BHRT) that delivers hormones through tiny pellets inserted just beneath the skin. The pellets dissolve slowly over three to six months, releasing steady levels of testosterone or estradiol to address symptoms caused by hormonal decline. It’s most commonly used by women going through perimenopause and menopause and by men experiencing age-related testosterone loss, sometimes called andropause.
How Pellet Therapy Works
The core idea behind BioTE is simple: rather than taking a daily pill, applying a patch, or using a cream, you receive a set of small pellets placed under the skin that release hormones gradually. Each pellet is cylindrical, roughly 3mm in diameter and 9mm long, about the size of a grain of rice. Because the hormones absorb steadily from the pellet, levels stay more consistent throughout the day compared to methods that can cause peaks and valleys.
The hormones in the pellets are called “bioidentical” because their chemical structure matches the hormones your body naturally produces. The two most common hormones delivered this way are testosterone and estradiol (a form of estrogen). Both men and women produce testosterone, though in different amounts, and the dosing reflects that. Women typically receive 50 to 225 mg of testosterone per session, while men typically receive 1,000 to 2,400 mg. The number of pellets inserted in a single visit ranges from 2 to 10, depending on the dose your provider determines you need.
What the Insertion Procedure Looks Like
The procedure itself is quick, usually taking 10 to 15 minutes in a provider’s office. You’ll lie face down on an exam table while the provider numbs a small area on your upper buttock or hip with a local anesthetic. That location is chosen because it has a reliable layer of fat beneath the skin and a low risk of hitting blood vessels.
Once the area is numb, the provider makes a tiny opening and uses a narrow instrument called a trocar to slide the pellets into place beneath the skin. No stitches are needed. The opening is closed with small adhesive strips, and you’re done. Most people describe the experience as feeling pressure but minimal pain after the numbing takes effect.
You’ll return for a new insertion every three to six months as the pellets fully dissolve. Your provider will check hormone levels through blood, urine, or saliva testing before each round to adjust the dose. BioTE uses proprietary clinical decision support software, built from roughly 30 years of clinical data, to help providers calculate individualized dosing. The goal is to titrate based on symptom relief rather than targeting a specific number on a lab report.
Recovery After Insertion
Post-procedure restrictions are minimal but worth following. Keep the insertion site completely dry for 24 hours. After that first day, showering is fine, but avoid soaking in tubs, pools, or baths for at least three days. Skip vigorous exercise for 72 hours, including running, biking, yoga, and aerobic workouts. Walking and light stair climbing are fine right away. You should also avoid heavy lifting, repetitive squatting, and strenuous housework like vacuuming for about three days. These precautions reduce the risk of bruising, drainage, and delayed healing at the insertion site.
Symptoms It Targets
Hormonal decline produces a cluster of symptoms that can significantly affect quality of life. BioTE pellet therapy is designed to address hot flashes, night sweats, vaginal dryness, painful intercourse, low libido, sleep disruption, fatigue, unexplained weight gain, mood swings, and memory fog. Not everyone experiences all of these, and the specific combination varies from person to person.
Some providers also point to longer-term protective effects of maintaining optimized hormone levels, particularly for bone density, cardiovascular health, and cognitive function. The rationale is that as women age, hormone receptors become less responsive, sometimes requiring higher hormone levels than younger women to achieve the same clinical benefit. This is one reason dosing is personalized and adjusted over time rather than set at a fixed amount.
Who May Not Be a Good Candidate
Hormone therapy of any kind carries risks for certain people. It may not be safe if you have or are at high risk for blood clotting disorders, heart or cardiovascular disease, breast cancer, or stroke. Your provider should review your full medical history and run baseline blood work before recommending pellet therapy. Ongoing monitoring through periodic lab testing is a standard part of the process.
What “Bioidentical” Means for Regulation
One important distinction that often causes confusion: BioTE pellets are custom-compounded, meaning they’re prepared by a compounding pharmacy to a specific dose for each patient. Compounded BHRT products are not FDA-approved. That doesn’t mean the individual hormones themselves are illegal or unregulated, but it does mean the specific pellet formulations have not undergone the FDA’s formal review process for quality, safety, effectiveness, and how reliably the drug enters the body.
This is a meaningful difference from FDA-approved hormone therapies, which have gone through large-scale clinical trials. The FDA has specifically noted that compounded BHRT products are sometimes used in place of approved drugs, and the agency has funded research into compounding practices to better understand the implications. For patients, the practical takeaway is that the quality of your pellet therapy depends heavily on the compounding pharmacy producing it and the provider monitoring your treatment.
Cost and Insurance
BioTE pellet therapy is generally an out-of-pocket expense. Most insurance plans do not cover compounded hormone pellets, and major insurers have classified implantable hormone pellets as not meeting standard coverage criteria. Costs vary by provider and region, but you can typically expect to pay somewhere between $300 and $500 per insertion for women and $600 to $900 for men, with treatments needed two to four times per year. Some practices offer membership plans or package pricing to reduce the per-visit cost.
How BioTE Compares to Other Hormone Delivery Methods
Hormone replacement therapy comes in many forms: oral pills, transdermal patches, topical creams and gels, injections, and pellets. The primary advantage of pellets is convenience and consistency. You don’t need to remember a daily application or schedule weekly injections. The slow, steady release also avoids the hormonal spikes that can come with other methods.
The main trade-off is that once pellets are inserted, the dose can’t be easily adjusted until they dissolve. With a cream or patch, your provider can change the dose immediately if side effects appear. With pellets, you’re committed to that dose for several months. This is why initial dosing accuracy and ongoing lab monitoring matter so much in pellet-based therapy.
