Your clinician needs recent blood work to prescribe safely. Two ways to get it done:

Precise weekly microdosing for women who don't absorb transdermal testosterone well. Titrated tightly to the female physiologic range using labs at 6–12 weeks.


Quick lab panel at 2,000+ locations near you — or upload recent bloodwork and we may use your existing results.

A licensed clinician reviews your levels, symptoms and goals, builds your personalized plan, and ships it to your door.


Most members notice improvements within weeks. We recheck labs at 90 days and fine-tune your dose.

Answer a few health questions — a licensed provider reviews online. No waiting rooms.

Once approved, your medication ships discreetly to your door.


Physician-guided support and check-ins keep results on track.

Inject 2-5 units (4-10 mg) subcutaneously once weekly; titrate per labs to female physiologic range
Controlled substance, DEA Schedule III. Baseline labs are required before your first prescription, with follow-up labs at 6 to 12 weeks to guide dosing. Benefits: Precise weekly microdosing for women who do not absorb transdermal testosterone well. Insulin syringes and sharps guidance are included. Risks: Androgenic effects if the dose runs high, which is why lab titration is required. Injection-site reactions.
The dose is a small fraction of what is used for men, drawn from the same concentration. The aim is restoring a normal female range, not raising testosterone beyond it.
Typically a small weekly subcutaneous injection. Your care team walks you through drawing an accurate small volume, which is the part that takes practice.
Injection gives more predictable levels than a topical, where absorption varies. The trade-off is the needle and the precision needed for a small dose.
Acne, unwanted hair growth and — rarely — voice changes, all of which suggest the dose is too high. Voice changes may not fully reverse, so report them promptly.
