Topical testosterone is absorbed through the skin and can cause side effects or symptoms of male features in a child or woman who comes into contact with this medicine.
Administration of ester derivatives of testosterone as testosterone cypionate generates an increase in serum testosterone to levels reaching 400% from the baseline within 24 hours of administration. These androgen levels remain elevated for 3-5 days after initial administration.
Testosterone cypionate is used to treat symptoms of hypogonadism in males. In this condition, males don't produce enough of the sex hormone testosterone. Low testosterone levels in males can lead to mood changes, poor concentration, erectile dysfunction (trouble getting or keeping an erection), and low sex drive.
Use of doping agents, particularly anabolic steroids, in sports and society. Significant anabolic effects occur at supraphysiologic testosterone levels (>1000 ng/dl), which generally requires weekly doses of 300 mg or more.
This medication is given by injection into the buttock muscle as directed by your doctor, usually every 1 to 4 weeks. Do not inject this medication into a vein. Dosage is based on your medical condition, testosterone blood levels, and response to treatment.
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.
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.
Store it at room temperature and away from light, excess heat and moisture (not in the bathroom). Do not refrigerate or freeze.
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.
Testosterone is a naturally occurring sex hormone that is produced in a man's testicles. Small amounts of testosterone are also produced in a woman's ovaries and adrenal system. Testosterone injection is used in men and boys to treat conditions caused by a lack of this hormone, such as delayed puberty or growth.
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).
While previous studies suggested a link between testosterone therapy and heart disease, the connection isn't clear. Some studies have reported that testosterone therapy might increase the risk of a heart attack in men age 65 and older, as well as in younger men who have a history of heart disease.
