Testosterone isn't just a male hormone. Women produce it too — and when levels drop, the effects on energy, libido, mood, and body composition can be significant. More women than ever are exploring testosterone replacement therapy, but reliable dosing information written specifically for women is hard to find online. This guide covers what the evidence says about how much testosterone a woman should inject per week, how providers determine the right dose, and what to watch for along the way.
What Is Normal Testosterone for Women?
Before discussing dosing, it helps to understand what constitutes a normal testosterone level in women. Women produce testosterone primarily through the ovaries and adrenal glands, at levels far lower than men.
| Life Stage | Total Testosterone (ng/dL) | Free Testosterone (pg/mL) |
|---|---|---|
| Premenopausal (20s–30s) | 20–70 | 1.0–3.5 |
| Perimenopause (40s) | 15–50 | 0.8–2.5 |
| Postmenopausal | 10–40 | 0.5–1.5 |
| Post-oophorectomy | 5–25 | 0.3–1.0 |
Testosterone peaks in a woman's early 20s and declines gradually — roughly 1–2% per year. By menopause, levels may be half of what they were at age 25. Women who have had their ovaries removed (oophorectomy) often experience the most dramatic drop, since the ovaries are a primary production site.
Lab Testing Note
Standard testosterone assays used for men are often too imprecise at the low ranges relevant for women. Ask your provider to order a sensitive (LC-MS/MS) testosterone assay rather than the standard immunoassay. This is the same method recommended by the Endocrine Society for accurate measurement in women and children.
Why Women Take TRT
Testosterone therapy in women is most commonly considered for symptoms that haven't adequately responded to estrogen and progesterone therapy alone. The most well-studied indication is hypoactive sexual desire disorder (HSDD) in postmenopausal women, where a 2019 systematic review and meta-analysis published in The Lancet Diabetes & Endocrinology demonstrated clear benefit.
Beyond libido, many providers — including our team at Highland Longevity — observe clinical improvements in several other areas when testosterone levels are restored to a physiological range:
- Energy and vitality: Reduced fatigue and improved stamina
- Mood: Better emotional resilience and reduced irritability
- Cognitive clarity: Less brain fog and improved focus
- Body composition: Improved lean muscle mass and metabolic rate
- Bone density: Supportive effect alongside estrogen therapy
- Sexual function: Improved desire, arousal, and satisfaction
It's worth noting that the Global Consensus Position Statement on testosterone therapy for women (published in 2019 across four major endocrinology journals) supports testosterone use for postmenopausal women with HSDD, while acknowledging that evidence for other indications is still emerging. We use testosterone as part of a comprehensive hormone replacement protocol and evaluate each patient individually.
Typical Weekly Dosing Ranges
This is the question most women searching this topic want answered: how much testosterone should I actually inject per week?
The short answer is 5–20 mg per week of testosterone cypionate, with most women falling in the 5–10 mg starting range. But the right dose for you depends on your baseline levels, symptoms, body weight, and how you respond. Here's how providers typically approach it:
| Weekly Dose | Typical Use | Expected Total T Range | Notes |
|---|---|---|---|
| 2–5 mg | Ultra-conservative start | 20–40 ng/dL | Used for sensitive patients, very low body weight, or those already on estrogen/progesterone |
| 5–10 mg | Most common starting dose | 30–60 ng/dL | Where most providers begin; well-tolerated by the majority of patients |
| 10–15 mg | Moderate / adjusted dose | 50–80 ng/dL | Titrated up after 6–8 weeks if symptoms persist and labs allow |
| 15–20 mg | Higher therapeutic range | 60–100 ng/dL | Less common; requires close monitoring for androgenic side effects |
Important Context
There is currently no FDA-approved testosterone product specifically for women in the United States. Providers prescribe testosterone cypionate (an FDA-approved male formulation) off-label at much lower doses. This is a common, well-established clinical practice supported by international medical consensus, but patients should understand the off-label nature of the prescription.
Because testosterone cypionate typically comes in a 200 mg/mL concentration (designed for male doses), providers often have compounding pharmacies prepare a lower concentration — commonly 20–50 mg/mL — to make accurate small-volume dosing easier and reduce injection errors.
How Doses Are Adjusted
Providers typically follow this pattern for dose optimization:
- Baseline labs: Total testosterone (sensitive assay), free testosterone, SHBG, DHEA-S, CBC, metabolic panel
- Start low: Begin at 5–10 mg/week
- Recheck at 6–8 weeks: Draw labs at trough (just before next injection) to assess levels
- Adjust based on both labs and symptoms: If levels are within range but symptoms persist, consider a modest increase; if side effects appear, reduce
- Ongoing monitoring: Labs every 3–6 months during the first year, then annually once stable
The goal is to restore testosterone to the mid-to-upper physiological range for premenopausal women — typically 30–70 ng/dL total testosterone — while watching for any signs of excess.

Subcutaneous vs Intramuscular Injection
Women using injectable testosterone generally choose between two injection routes. Both are effective, and the choice often comes down to comfort, absorption consistency, and provider preference.
| Factor | Subcutaneous (SubQ) | Intramuscular (IM) |
|---|---|---|
| Needle size | 27–30 gauge, ½″ length | 23–25 gauge, 1″ length |
| Injection site | Abdomen or outer thigh (fatty tissue) | Deltoid, ventrogluteal, or vastus lateralis (muscle) |
| Pain level | Minimal — most patients report little to no discomfort | Mild — deeper injection, slightly more noticeable |
| Absorption | Slower, steadier release from fat tissue | Slightly faster peak, more pronounced trough |
| Level stability | More stable at low doses | Adequate, especially with frequent dosing |
| Ease of self-injection | Very easy — simple pinch-and-inject technique | Moderate — requires comfort with deeper injection |
Other Delivery Methods
While this article focuses on injections (the most common method when precision dosing matters), women may also encounter testosterone delivered via compounded creams, pellets, or transdermal patches. Each has pros and cons. Injections offer the most precise dose control and consistent absorption, which is why many providers prefer them for women who need careful titration.
Side Effects to Watch
At physiological doses (5–20 mg/week), most women tolerate testosterone well. Side effects are generally dose-dependent, meaning they tend to appear when levels climb above the normal female range and typically resolve when the dose is reduced.
Common (Dose-Dependent) Side Effects
- Acne or oily skin: The most frequently reported side effect; usually mild and manageable with skincare adjustments
- Increased facial or body hair: Fine vellus hair may become slightly more noticeable, particularly on the chin or upper lip
- Scalp hair changes: Some women notice mild thinning; this is more common at higher doses and in those with a genetic predisposition
- Mood changes: Occasionally increased irritability, though many women report the opposite — improved mood stability
Uncommon / Signs to Reduce Dose
- Voice deepening: Rare at therapeutic doses; if noticed, dose should be reduced immediately as this may not fully reverse
- Clitoral enlargement: Very rare at physiological doses; associated with supraphysiological levels
- Significant hair loss: More than normal shedding warrants dose evaluation
- Elevated hematocrit: Less common in women than men, but should be monitored via CBC
When to Contact Your Provider
If you notice voice changes, persistent acne that doesn't respond to topical treatment, or any masculinizing effects, contact your provider promptly. These are signals that your dose may need adjustment. Most side effects are fully reversible when caught early — the key is recognizing when your protocol needs a change.
What About Breast Cancer Risk?
This is a common concern. Current evidence does not support an increased risk of breast cancer with physiological testosterone therapy in women. Some observational data suggest a possible protective effect, though this requires further study. The 2019 Global Consensus Statement concluded that "the current evidence does not support an association between testosterone therapy and increased risk of breast cancer in postmenopausal women." Patients with a history of hormone-sensitive breast cancer should discuss risks and benefits thoroughly with their oncologist and prescribing provider.
Does This Sound Like What You're Experiencing?
If you're reading this because you've been feeling off — low energy, missing your drive, changes in mood or body composition — your testosterone levels are worth checking. A simple blood draw can tell you whether low T is contributing.
At Highland Longevity in Fort Worth, we run a comprehensive hormone panel — not just total T — so you know exactly where you stand.
How Highland Longevity Doses This for Our Patients
At Highland Longevity, testosterone therapy for women is never a standalone treatment. We approach it as one component of a comprehensive hormone optimization strategy, typically alongside estradiol and progesterone where indicated.
Here's what our process looks like:
- Comprehensive labs first: We order a sensitive testosterone assay (LC-MS/MS), free testosterone, SHBG, DHEA-S, estradiol, progesterone, thyroid panel, CBC, and metabolic panel before prescribing anything
- Clinical correlation: Lab numbers alone don't tell the whole story. We discuss your symptoms, health history, and goals in detail
- Conservative start: Most of our female patients begin at 5–10 mg/week of testosterone cypionate via subcutaneous injection
- Compounded formulations: We work with compounding pharmacies to provide lower-concentration preparations (typically 20–50 mg/mL) that make accurate dosing simple
- Follow-up at 6–8 weeks: Repeat labs plus a symptom check to determine if adjustment is needed
- Ongoing optimization: We continue monitoring every 3–6 months during the first year, then adjust the schedule based on stability
We also use DEXA body composition scans to objectively track changes in lean mass and fat distribution — especially valuable for women who are using testosterone partly for body composition goals. Combined with resting metabolic rate testing, this gives us a full picture of how your body is responding.

Frequently Asked Questions
How much testosterone should a woman inject per week?
Most women on testosterone therapy inject between 5–20 mg of testosterone cypionate per week, with many providers starting at 5–10 mg and adjusting based on symptoms and lab results. The exact dose depends on baseline hormone levels, symptoms, body composition, and individual response. Doses for women are roughly one-tenth of typical male TRT doses.
What is a normal testosterone level for women?
Normal total testosterone for premenopausal women is generally 15–70 ng/dL, though this varies by lab and assay. Free testosterone levels are typically 0.5–3.5 pg/mL. Testosterone naturally declines with age, and by menopause many women have levels below 25 ng/dL. Optimal levels for symptom relief during TRT are individualized and determined by clinical response.
Do women inject testosterone subcutaneously or intramuscularly?
Both subcutaneous (SubQ) and intramuscular (IM) injection routes are used for women's testosterone therapy. Many providers prefer subcutaneous injections because they use a smaller needle, are less painful, and produce more stable hormone levels at the low doses women require. SubQ injections are typically given into the abdomen or thigh fat.
What are the side effects of testosterone in women?
At appropriate physiological doses, side effects are uncommon but may include acne, oily skin, mild facial hair growth, or hair thinning. These effects are typically dose-dependent and resolve with dosage reduction. Serious virilization (voice deepening, clitoral enlargement) is rare at therapeutic doses and more associated with supraphysiological dosing. Regular monitoring helps catch issues early.
