Your doctor will decide a dosage based on your needs. In general, the dosage is 50-400 mg injected into your muscle every 2-4 weeks. Dosage increases: Your doctor may adjust your dosage based on your testosterone blood levels, response to treatment, and side effects.
The usual adult dose of testosterone cypionate in men is 200 mg every two weeks, to a maximum of 400 mg per month. It is given as an injection into the gluteal muscle (buttocks) by a doctor. It is important this medication be given exactly as recommended by your doctor.
Levels of circulating testosterone peak within 10 to 12 hours of initial administration, and reach steady state within 24 hours (14).
Effects on sexual interest appear after 3 weeks plateauing at 6 weeks, with no further increments expected beyond. Changes in erections/ejaculations may require up to 6 months. Effects on quality of life manifest within 3-4 weeks, but maximum benefits take longer.
Side effects of testosterone therapy for women can include acne, extra hair growth, weight gain, and fluid retention. Some women have mood swings and become angry or hostile. In rarer circumstances, women develop deeper voices and baldness. Clitoral enlargement is another rare side effect.
In women, normal testosterone levels range from 15 to 70 nanograms per deciliter (ng/dL) of blood. Testosterone levels lower than 15 ng/dL may cause: changes in breast tissue.
Since the commercially available dosages are too strong for women, female patients typically are treated with testosterone compounded at a dosage of 0.5 to 2 mg per day.
Serum testosterone concentrations are diurnal. In young men, the concentrations are highest in the morning. Older men tend to have similar, but blunted, patterns. Clinicians should draw serum testosterone levels between 8:00 am and 11:00 am.
Its molecular formula is C27H40O3, and the molecular weight 412.61. Testosterone cypionate injection, USP is available in two strengths, 100 mg/mL and 200 mg/mL testosterone cypionate.

Usually, you will also be recommended HRT alongside testosterone as well as vaginal oestrogen if needed to treat vaginal dryness. It can sometimes take a few months for the full effects of testosterone to work; a 3-6 month trial is often recommended.
In clinical trials of women with HSDD, approximately 2/3 of women responded positively to testosterone therapy (compared to 1/3 using placebo). The trials demonstrated that response may not be immediate, taking 8-12 weeks in some instances for the effect to become clinically significant.
Common Testosterone Injection Questions. What's the best time of day to inject testosterone? Traditionally, it's the morning. It's not scientifically necessary to inject testosterone in the morning, though our testosterone is at the highest levels in the morning.
1 ml per week is 200 mg per week of testosterone. This is a replacement dose not shown to increase lean mass significantly in the short term. However, using higher doses may also increase red blood cell production and blood viscosity, so your doctor needs to monitor your hematocrit blood levels.
Testosterone injections are typically intramuscular - that is, given directly into a muscle. Two relatively easy and accessible sites for intramuscular injection are the deltoid (upper arm) or the glut (upper back portion of the thigh, ie, the butt cheek).
Testosterone is metabolized to various 17-keto steroids through two different pathways. The half-life of testosterone cypionate when injected intramuscularly is approximately eight days.
