Testosterone pellets for women: what the evidence actually says

What did @keepingupwithkarleec actually say?

She described a pretty common clinical frustration: testosterone pellets inserted five weeks ago, a brief energy bump around week two, then nothing. Bloodwork at four weeks showed her levels "had come up just a tiny bit" but were still low, and her provider called her back in for a supplemental pellet dose she's calling a "booster." That's the whole story, and it's actually more medically grounded than most hormone content on TikTok.

She didn't claim pellets cured anything. She didn't tell viewers to try this at home. She shared a clinical process, including the bloodwork step, which is exactly how this is supposed to work. The framing is personal and honest. Her main implicit claim is that a booster pellet dose is a reasonable clinical response to inadequate levels, and that's worth examining carefully.

Does the science back this up?

Mostly, yes. Testosterone pellets have real pharmacokinetic variability, and underdosing on the first insertion is genuinely common, especially in women. A supplemental dose based on labs is a recognized clinical adjustment, not a red flag.

Pellet absorption in women varies significantly based on activity level, body composition, and individual metabolism. A 2012 study by Glaser and Dimitrakakis published in Maturitas found that physically active women metabolized pellets faster than sedentary women, sometimes requiring dose adjustments between standard insertion cycles. The typical pellet cycle for women runs 3 to 5 months, but the first insertion is often intentionally conservative because providers are calibrating to an individual patient. Glaser's group also found that symptom relief in women correlated better with free testosterone levels than total testosterone, which raises a question her video doesn't address: which marker is her provider actually targeting? That detail matters more than it sounds.

What did they get right or wrong?

She got the process right. Bloodwork at four weeks to assess levels, symptom check-in from the provider, and a dose adjustment based on results is a clinically reasonable sequence. Credit where it's due.

The terminology is slightly loose but not harmful. Calling it a "testosterone booster" is the kind of casual language that makes supplement companies wealthy, but in context it's clear she means a supplemental pellet insertion, not a pill from a gas station shelf. Viewers who don't know the difference could walk away confused, though.

The bigger omission is that she doesn't mention what "low" actually means for her. Normal testosterone ranges for women are genuinely contested. The Endocrine Society uses 15 to 70 ng/dL as a rough reference range for premenopausal women, but many testosterone pellet clinics target levels that sit well above that, sometimes in the 150 to 200 ng/dL range. A 2019 position statement from the Global Consensus Position Statement on the Use of Testosterone Therapy for Women, published in the Journal of Clinical Endocrinology and Metabolism, specifically warned against targeting supraphysiologic levels without evidence of benefit. That context is missing from her video entirely.

What should you actually know?

Pellet dosing in women is not standardized across providers, and that is a real problem worth knowing about before you commit to the therapy.

Unlike injectable testosterone or gels, pellets cannot be adjusted once inserted. If you absorb a dose faster than expected, or if the dose turns out to be too high, you wait it out. That inflexibility cuts both ways: it's convenient when things go right, and it's a problem when they don't. Androgenic side effects like acne, hair thinning, or voice changes from excess testosterone are not always reversible quickly when the delivery method is subcutaneous pellets. The 2019 global consensus statement by Davis, Baber, Panay, and colleagues noted that evidence for pellets specifically is more limited than for other delivery methods, and they are not approved by the FDA for testosterone therapy in women. That doesn't make them unsafe, but it does mean the dosing protocols vary widely depending on who your provider is. If your clinic isn't running bloodwork before and after insertion and adjusting based on symptoms and labs together, that's worth asking about directly.
