Pellet therapy vs HRT: why NAMS advises against pellets
Hormone pellets are compressed cylinders of testosterone and/or estradiol inserted under the skin every 3–4 months. Pellet clinics market them as 'the natural way' or the 'set-and-forget' option. Every major menopause society — NAMS, ACOG, Endocrine Society, and the International Menopause Society — advises against pellet therapy for routine menopause care. Here's why.
What pellets are
A hormone pellet is a compressed cylinder of estradiol (typically 12–25 mg) or testosterone (75–200 mg) inserted subcutaneously in the hip or buttock through a small incision. It dissolves over 3–4 months, releasing hormone continuously.
The dosing problem
Once a pellet is in, it can't be adjusted. If your estradiol level lands at 300 pg/mL — three times normal — you either wait months for it to dissolve or have the pellet surgically removed. Testosterone pellets in women commonly produce free testosterone levels in the male range. Studies of pellet users show mean estradiol 200–400 pg/mL vs 50–100 on standard transdermal HRT.
What professional societies say
- NAMS 2022: "Compounded bioidentical hormones, including pellets, are not recommended."
- ACOG Committee Opinion 532: advises against pellets for menopause care.
- Endocrine Society: recommends against pellets given supraphysiologic dosing and lack of trial data.
- British Menopause Society: does not endorse pellet implants.
Where pellet clinics get customers
Pellets are highly profitable — $500 in materials at markup, quick procedure, cash-pay. Marketing emphasizes convenience ("no daily patch") and "optimization" language that implies pellets exceed standard HRT. The evidence does not support that claim.
The Kindr alternative
Transdermal estradiol (patch, gel, or cream) plus oral micronized progesterone delivers the same physiologic estradiol level, is titratable within days, is FDA-regulated in most forms, and costs $79/mo including medication. When testosterone is clinically indicated, we use compounded transdermal cream — physiologic dose, easy to stop.
If you have pellets already
Do not remove them impulsively. Levels normalize over 4–6 months. A Kindr provider can help you transition to a standard, titratable regimen at your next cycle.
Frequently asked questions
Are hormone pellets FDA-approved?
No estrogen or testosterone pellet for women is FDA-approved. All pellets used in the US are compounded, meaning there is no standardized dosing.
Why does NAMS advise against pellets?
NAMS position statements cite supraphysiologic dosing, inability to titrate, hair loss and voice changes from excess testosterone, and lack of an efficacy signal beyond standard HRT.
What are the side effects of pellets?
Unwanted facial hair, acne, voice deepening, hair loss on the scalp, insertion-site infection, pellet extrusion, and estradiol levels 2–5x normal premenopausal range.
How much do pellets cost?
$300–$800 per insertion, every 3–4 months, out of pocket. Not covered by insurance. Annual cost typically $1,500–$3,500.
What should I do instead?
Standard transdermal estradiol + oral micronized progesterone, plus low-dose transdermal testosterone if needed for libido. Same physiologic outcome, titratable, evidence-based, and often 1/5 the annual cost.
