Testosterone therapy for women: separating TikTok hype from clinical data

What did @rmdywellness actually say?

The creator confirmed they personally use testosterone pellets and also offer injections, describing both as available to men and women. The specific claims were about duration: pellets last "6 to 8 months" for men and "3 to 4 months" for women. For injections, men should dose "weekly" and women "every other week." That's the whole video. No dosing amounts, no brand names, just frequency and duration windows. Credit where it's due: keeping it at that level of specificity is actually responsible for a TikTok. But the numbers themselves deserve scrutiny, because some are solidly supported and some are more optimistic than the clinical literature typically is.

Does the science back this up?

Partially. The pellet duration claims are where things get complicated. The injection frequency claims, by contrast, are roughly defensible for standard protocols, though they leave out a lot of important context.

On pellets: the most widely cited data comes from Glaser et al. (2013, Maturitas), which studied subcutaneous testosterone pellets in women and found therapeutic levels sustained for roughly 3 to 5 months depending on dose and individual metabolism. So the "3 to 4 months" figure for women is on the conservative end of real-world data, which is fine. For men, however, "6 to 8 months" is optimistic. A 2014 review by Pastuszak et al. (Journal of Sexual Medicine) noted that male pellet duration typically runs 4 to 6 months before levels drop below therapeutic range, with some patients requiring re-insertion closer to the 4-month mark. Saying 6 to 8 months isn't outright wrong, but it describes the ceiling, not the average.

On injection frequency: weekly testosterone cypionate or enanthate for men is the standard protocol in most U.S. TRT practice and aligns with pharmacokinetic half-life data. Every-other-week for women is less standardized. Women typically receive much lower doses and some clinicians do use biweekly schedules, but this varies considerably by individual response.

What did they get wrong (or right)?

The male pellet duration claim is the clearest overstatement. Saying pellets last "6 to 8 months" for men sets an expectation that many patients won't meet. The peer-reviewed data points to 4 to 6 months as a more accurate central estimate. Patients who go in expecting 8 months and need re-insertion at month 4 may feel misled, and that matters clinically.

The women's pellet window of "3 to 4 months" is actually reasonable and consistent with Glaser's data, so credit there.

The injection frequency guidance, "weekly" for men and "every other week" for women, is broadly consistent with common clinical practice in telehealth and outpatient TRT settings. But it's worth noting these are not universal standards. Some men do fine on every-other-week injections of longer esters, and some women require more frequent low-dose administration for stable levels. The framing of these as fixed rules, rather than starting points, is a mild oversimplification.

What the creator did not do: recommend specific doses, make disease cure claims, or compare compounded testosterone to brand-name products. That's worth noting as a baseline of responsible content.

What should you actually know?

Testosterone pellet duration is not a fixed window. It depends on the dose inserted, your metabolic rate, activity level, and body composition. Men who exercise heavily or have higher testosterone clearance will often fall on the shorter end of any published range. Assuming 8 months between insertions without monitoring levels is a mistake.

Injection frequency for women is genuinely variable. Some clinicians use weekly low-dose subcutaneous injections for women specifically because they produce more stable serum levels than biweekly intramuscular shots. The "every other week" framing is not wrong, but it's one option among several, and the right schedule depends on lab work, not a general rule from a short video.

The bigger takeaway is that any testosterone protocol, pellet or injection, requires regular monitoring of serum testosterone, hematocrit, and symptom response. No TikTok video, including this one, can substitute for that. If a provider is setting your insertion or injection schedule without ongoing labs, that's a problem regardless of what the general windows are.
