@kelly_keelan's testosterone therapy claims, fact-checked

What did @kelly_keelan actually say?

Kelly Keelan told her 18,000-plus viewers that women who cannot access a prescribing provider have a legitimate workaround: take their husband's testosterone, buy sterile vials and carrier oil online, and dilute it themselves at home. She named Tailor-Made and Empower as compounding pharmacies that offer women-specific concentrations, cited 20 mg/mL as the appropriate strength for women, and offered to post a step-by-step tutorial. Her framing was pragmatic: "do what you have to do."

She also made a pharmacokinetics argument, stating that drawing a female dose from a 200 mg/mL vial produces a volume so small it is inaccurate in the syringe and may not absorb properly after injection. That part is actually worth taking seriously, even if the solution she proposes is not.

Does the science back this up?

The concentration argument has real support. The accuracy problem does not justify compounding testosterone in your kitchen sink.

On dosing accuracy: women's physiologic testosterone targets are roughly 15 to 70 ng/dL, and therapeutic subcutaneous doses typically fall between 2 and 10 mg per week. Drawing that from a 200 mg/mL vial means measuring 0.01 to 0.05 mL, which is below the reliable read range of most insulin syringes. Mishkin et al. (2021, Journal of Clinical Endocrinology and Metabolism) and clinical guidance from the Endocrine Society both acknowledge this syringe-accuracy problem as a genuine barrier to precision dosing in women.

On home compounding: there is no peer-reviewed evidence that lay people can reliably produce sterile injectable preparations. Pharmaceutical-grade compounding requires controlled environments, validated mixing procedures, and sterility testing. A 2013 meningitis outbreak linked to contaminated compounded methylprednisolone, documented by Kainer et al. (2012, NEJM), killed 64 people and remains the clearest real-world example of what happens when sterility fails outside licensed facilities.

What did they get wrong (or right)?

She got the concentration problem right and the proposed solution badly wrong.

Credit where it is due: 20 mg/mL is a commonly used women's formulation from licensed compounding pharmacies. Empower and Tailor-Made are both PCAB-accredited facilities operating under state pharmacy board oversight. The frustration with access barriers is legitimate. Davis et al. (2019, Lancet Diabetes and Endocrinology) documented that testosterone prescribing for women remains inconsistent and under-supported across most health systems.

But "if you get the right sterile products, it's totally fine" is not how sterility works. Endotoxin contamination, particulate matter, and improper pH are invisible to the naked eye. A sterile vial purchased online and filled at home is not a pharmaceutical-grade product, regardless of how careful you are. Beyond safety, this is legally fraught. Sharing or redistributing a controlled substance, which testosterone is (Schedule III in the US), is a federal offense even within a household. Encouraging women to use their husband's prescription for themselves is describing off-label diversion of a controlled substance.

What should you actually know?

The access gap is real. The DIY workaround carries serious and underappreciated risks.

Testosterone is a Schedule III controlled substance under the Controlled Substances Act. Using a prescription issued to another person, including a spouse, is illegal under federal law regardless of the dose or intent. Injectable preparations require pharmaceutical-grade sterility standards that cannot be replicated in a home setting. The risks include infection, abscess, sepsis, and systemic contamination.

If you are having trouble finding a provider, telehealth platforms operating under physician oversight can prescribe and route to licensed compounding pharmacies directly. That is a slower and sometimes more expensive path than borrowing your husband's vial, but it is the one with actual quality controls behind it. The 20 mg/mL concentration point is clinically reasonable as a target, but only when it comes from a licensed, regulated source with sterility testing on file.

• Women's testosterone prescribing access is a documented systemic problem (Davis et al., 2019, Lancet Diabetes and Endocrinology).
• Syringe accuracy at sub-0.05 mL volumes is a legitimate clinical concern.
• Home compounding of injectables bypasses every safety check that exists to prevent contamination.
• Redistribution of a Schedule III controlled substance is a federal offense.
• Licensed compounding pharmacies operate under state board oversight and, when PCAB-accredited, meet additional quality standards.
