There is no single correct TRT dosage per week. FDA labeling for testosterone cypionate injection lists 50 to 400 mg every 2 to 4 weeks for men with diagnosed hypogonadism, and the one weekly injectable product, Xyosted, starts at 75 mg once a week. Your prescriber picks a starting dose in milligrams and adjusts it to your blood levels, symptoms and side effects. Whether 0.5 mL or 1 mL is “enough” depends on your vial strength and lab results, not on the volume. [1,2]
Key takeaways
- Doses are prescribed in mg. 0.5 mL is 50 mg from a 100 mg/mL vial and 100 mg from a 200 mg/mL vial (calculated). [1]
- Labeled intramuscular regimens are 50-400 mg every 2-4 weeks, roughly 12.5-200 mg per week when expressed weekly (calculated); Xyosted starts at 75 mg weekly under the skin. [1,2]
- 200 mg per week (1 mL of a 200 mg/mL vial) is the top of the labeled range, not a routine starting dose. [1]
- Testosterone is for men with confirmed hypogonadism: symptoms plus low morning testosterone on at least two separate days. [1,3]
Do not change your dose on your own
Testosterone is a Schedule III controlled substance. Abuse at higher-than-recommended doses has been linked to heart attack, stroke, liver injury and serious psychiatric effects. Change the volume you inject only when your prescriber tells you to. [1]
Understanding Testosterone Dosage Per Week
Your weekly testosterone dose is a number of milligrams set by a prescriber after a diagnosis of hypogonadism. The labels say dosage is adjusted to the patient’s response and to adverse reactions, so two men on the same product can end up on different weekly doses. [1]
Before any dose: confirming the diagnosis
Testosterone therapy is only for men diagnosed with low testosterone (hypogonadism): symptoms plus total testosterone measured in the morning on at least two separate days and found below the normal range. Dosing questions come after that diagnosis, not before it. [1,2,3]
FDA approves testosterone for men with low testosterone caused by specific conditions of the testicles, pituitary or hypothalamus. Its safety and effectiveness for low testosterone due to aging alone (“age-related hypogonadism”) have not been established, and it is not approved for anti-aging or general wellness. [1,4]
Typical TRT Dosage Per Week: What’s Standard?
The FDA-labeled regimen for intramuscular testosterone cypionate is 50 to 400 mg every 2 to 4 weeks. Expressed per week, that is about 12.5 to 200 mg (calculated). Many clinicians split the total into weekly doses, a schedule chosen by the prescriber rather than the one in the label. The weekly subcutaneous product Xyosted starts at 75 mg once a week. [1,2]
So what is a normal weekly dose of testosterone? There is no single average TRT dose per week; the common TRT dosage is whatever brings your levels into the target range. In Xyosted’s trials, patients started on 75 mg weekly and were moved to 50 mg or 100 mg as needed. [2]
Standard Dosage in mg and mL
How much test cypionate per week is typical? The weekly equivalent of the label is about 12.5 to 200 mg (calculated). If you use Test E (enanthate), ask your prescriber how your product’s label compares. How many mL of testosterone per week that means depends on the vial strength: [1]
- 0.5 mL per week = 50 mg (100 mg/mL vial) or 100 mg (200 mg/mL vial), calculated
- 1 mL per week = 100 mg (100 mg/mL vial) or 200 mg (200 mg/mL vial), calculated [1]
Testosterone is a Schedule III controlled substance under the Controlled Substances Act and is dispensed only with a prescription. [1]
Why TRT Dosage Is Individualized
Treatment aims for testosterone in the mid-normal range while weighing side effects and patient preference. [1,3] Your prescriber considers:
- Baseline total testosterone (and, where relevant, free testosterone and SHBG)
- Hematocrit, PSA and blood pressure before and during treatment
- The product, route and schedule (weekly or every 2 weeks, under the skin or into muscle) [1,2]
- Age, other conditions, medications and your symptoms
- Whether you plan to father children in the near term
Testosterone dose chart: mL to mg by concentration
To convert mL to mg, multiply the volume by the concentration printed on the vial: mg = mL x mg/mL. Testosterone cypionate is supplied in 100 mg/mL and 200 mg/mL vials; other products and compounded preparations may use other strengths, so always read your own label. [1]
| Weekly volume | 100 mg/mL vial | 200 mg/mL vial | Vs. labeled range (about 12.5-200 mg/week) |
|---|---|---|---|
| 0.5 mL | 50 mg | 100 mg | Within range [1] |
| 0.6 mL | 60 mg | 120 mg | Within range [1] |
| 1 mL | 100 mg | 200 mg | 200 mg is the top of the range [1] |
| 3 mL | 300 mg | 600 mg | Above the labeled range [1] |
| 5 mL | 500 mg | 1,000 mg | Far above the labeled range [1] |
All values are calculated; the chart is arithmetic, not a dosing recommendation. 1 mL is the same volume as 1 cc, and 0.5ml, 0.6ml, 1ml or 50mg mean the same as 0.5 mL, 0.6 mL, 1 mL or 50 mg. [1] For step-by-step conversions see converting 200 mg of testosterone to mL, and for the 1 cc question see is 1 cc of testosterone a week enough.
Is 0.5 mL of Testosterone per Week Enough?
Is 0.5 mL of testosterone a week enough? It is 50 mg from a 100 mg/mL vial or 100 mg from a 200 mg/mL vial (calculated), and both amounts fall inside the weekly equivalent of the labeled range. Whether it is enough for you is decided by your follow-up blood test and symptoms, not by the volume. [1,3]
Is .5 mL of testosterone a lot? No: in mg it sits in the lower-to-middle part of the labeled range, and 0.6 mL is read the same way. Some men reach the target level on this amount; others need more or less. [1,2] For a deeper look at the 100 mg end of the range, see what 100-500 mg doses mean.
What to Watch at This Dose
- Lab results: is total testosterone in the target range your prescriber set? [3]
- Symptom relief: have the symptoms that led to your diagnosis improved? [5]
- Side effects: hematocrit and blood pressure, which can rise at any dose. [4,6]
Some prescribers split a weekly dose into two injections, for example 50 mg twice per week. This is a clinician’s choice to reduce peaks and dips; it is not the labeled schedule, which is every 2 to 4 weeks. [1]
Is 1 mL of testosterone a week enough, or too much?
Is 1 mL of testosterone a week enough? From a 200 mg/mL vial, 1 mL a week is 200 mg (calculated), the top of the labeled range expressed weekly; from a 100 mg/mL vial it is 100 mg. At 200 mg it is a high dose that needs a documented reason and closer monitoring. [1]
Is 1 mL of testosterone a lot? At 200 mg/mL, yes: the cypionate maximum of 400 mg every 2 weeks equals 200 mg a week (calculated), so 1 mL weekly from that vial sits at the top of the labeled range. [1] How much will 1 mL of testosterone raise your levels? It cannot be predicted; the response differs between men, so blood is rechecked after a start or change. [2,3] More detail on this dose: 200 mg per week: levels, results and risks.
Potential concerns at 200 mg weekly, and at any dose
These risks apply at any dose of testosterone, and some, such as a rise in red blood cell count, tend to be greater with higher exposure: [4,6]
- Higher blood pressure (FDA confirmed a class-wide increase) [4]
- Higher hematocrit (thicker blood) [2,6]
- Suppressed sperm production and reduced fertility [2]
- PSA increase and worsening urinary symptoms in men with an enlarged prostate [2]
What about 3 mL or 5 mL a week?
Is 3 mL of testosterone a week enough, or is 5 mL of testosterone a week enough? These volumes are 300 to 1,000 mg a week depending on the vial (calculated), well above the labeled range for replacement therapy. Abuse typically happens at such doses; see 300 mg per week for why such doses are not replacement therapy. [1]
How is the right TRT dose decided? (labs, targets, titration)
Your prescriber decides by measuring testosterone after you start, comparing it with a target range, and adjusting in small steps. Guidelines aim for testosterone in the mid-normal range and a standard monitoring plan that covers symptoms, side effects, testosterone and hematocrit. That is how to know if a TRT dosage is correct. [3,5]
The Xyosted label gives the clearest example of titration. Total testosterone is measured 7 days after the latest weekly dose (the trough), after 6 weeks of dosing and again 6 weeks after any change. A trough of 350 to 650 ng/dL keeps the level in the normal range; the dose is cut by 25 mg if the trough is 650 ng/dL or higher and raised by 25 mg if it is below 350 ng/dL. [2] These numbers belong to Xyosted. For intramuscular cypionate or enanthate, your prescriber decides when in the injection cycle blood is drawn, so ask which point your result reflects.
Ongoing Monitoring Is Essential
Regular monitoring is recommended in the FDA prescribing information and medical guidelines because it catches problems such as a rising red blood cell count or blood pressure early. Expect blood tests about 6 weeks after you start or change your dose, then at intervals your clinician sets. [2,3]
Monitoring usually includes testosterone, hematocrit, blood pressure and, for many men, PSA. The Xyosted label advises checking hematocrit before starting and about every 3 months; labels advise checking blood pressure periodically. [2,3]
Why Some Patients Adjust Their Dose
Doses go up or down when follow-up levels are outside the target range, side effects appear or symptoms change. The prescriber adjusts in small steps and rechecks blood; a dose is never raised for faster results. [1,2]
Injection frequency: weekly, twice weekly or every 2 to 4 weeks?
The labeled schedule for intramuscular testosterone cypionate is every 2 to 4 weeks. Many clinicians instead split the same amount into weekly or twice-weekly injections to reduce peaks and dips; your prescriber chooses the schedule that fits you. [1]

Possible Benefits of Testosterone Replacement Therapy
For men with symptomatic, confirmed testosterone deficiency, guidelines recommend testosterone therapy to correct the symptoms of deficiency and to maintain male sex characteristics. Benefits are individual and not guaranteed. [1,3]
Your prescriber judges benefit by whether the symptoms that led to the diagnosis improve once your level is in range. [5] Testosterone is not approved for anti-aging or general wellness, and its safety and effectiveness for age-related low testosterone have not been established. [4]
Known Risks and Side Effects
Every dose carries risks; the most common listed adverse reactions are higher hematocrit, higher blood pressure, PSA increase, injection-site bruising and headache. [2,4]
- Higher hematocrit and clot risk. In a network meta-analysis of 29 trials (3,393 men), all formulations raised hematocrit; intramuscular cypionate or enanthate raised it by about 4.0 percentage points. [6] In Xyosted’s trials, hematocrit reached 55% or more in 12 of 283 patients. [2]
- Blood pressure. FDA confirmed a class-wide increase in blood pressure with all testosterone products in 2025. [4]
- Heart. In the TRAVERSE trial, testosterone was noninferior to placebo for major heart events (hazard ratio 0.96, 95% CI 0.78-1.17), but atrial fibrillation, acute kidney injury and pulmonary embolism were more frequent. [4,7]
- Fertility. Testosterone can suppress sperm production and reduce fertility. [2]
- Prostate. PSA can rise, and urinary symptoms from an enlarged prostate can worsen. [2,3]
- Sleep apnea, acne and oily skin. Testosterone can worsen sleep apnea, especially with risk factors such as obesity, and untreated severe sleep apnea is a reason not to start. Acne and oily skin are listed adverse reactions. [1,2,3]
Fluid retention (edema) is another possible effect, and can be serious in men with heart, kidney or liver disease; see water retention on testosterone. [1,2]
Who should not use testosterone
Testosterone therapy is not appropriate if you have prostate or breast cancer, want to father a child soon, have a high hematocrit, untreated severe sleep apnea, severe urinary symptoms, uncontrolled high blood pressure or heart failure, a clotting disorder, or had a heart attack or stroke in the past 6 months. A PSA above 4 ng/mL (above 3 ng/mL in higher-risk men) needs urological evaluation first. [3] Before you start, your clinician should go over the benefits and risks with you, as the Endocrine Society recommends and the prescribing information describes. [1,3]
