Description:

 

Methyltestosterone is a 17-alpha-alkylated anabolic steroid used to treat men with a testosterone deficiency. It is also used in women to treat breast cancer, breast pain, swelling due to pregnancy, and with the addition of estrogen it can treat symptoms of menopause.

 

 

Methyltestosterone for Men

 

To treat androgen insufficiency, prescribing guidelines call for a daily dosage of 10-40 mg.When used for physique- or performance-enhancing purposes, a daily dosage of 10-50 mg is most commonly used, taken in cycles lasting no more than 6-8 weeks in length.

 

 

methyltestosterone For Women

 

Methyltestosterone is generally not recommended for women for physique- or performance-enhancing purposes due to its strong androgenic nature and tendency to produce virilizing side effects.

 

 

Applications:

 

Methyltestosterone is a steroid hormone from the androgen and is found in mammals and other vertebrates, Methyltestosterone is primarily secreted in the tests of mails and the ovaries of female, although small amount are also secreted by the adrenal glands, Methyltestosterone is the principle male sex hormone and an anabolic steroid. Methyltestosterone plays a key role in the development of male reproductive tissue such as the testis and prostates. In addition, Methyltestosterone is essential for health and well-being as well as the prevention of osteoporosis, Methyltestosterone is conserved through most vertebrates, although fish make a slightly difference from called 11-ketotestosterone.

Usage: for androgen and Albumen Assimilation steriodacetone(1:10) .

What is methyltestosterone?

 

 

Methyltestosterone is a man-made form of testosterone, 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.

 

Methyltestosterone is used in men and boys to treat conditions caused by a lack of this hormone, such as delayed puberty or other hormonal imbalances. Methyltestosterone is also used in women to treat breast cancer that has spread to other parts of the body.

Methyltestosterone may also be used for purposes not listed in this medication guide.

Methyltestosterone dosing information

 

Usual Adult Dose for Hypogonadism -- Male:

 

10 to 50 mg orally once a day.

-or-
5 to 25 mg buccal tablet once a day. Buccal administration allows direct absorption of methyltestosterone into the systemic venous system resulting in delivery of unmetabolized drug to the target tissue. Potency of buccal tablets is 2 times that of oral methyltestosterone.

 

Usual Adult Dose for Breast Cancer--Palliative:

 

50 to 200 mg orally per day in divided doses.
-or-
25 to 100 mg buccal tablet per day. Buccal administration allows direct absorption of methyltestosterone into the systemic venous system resulting in delivery of unmetabolized drug to the target tissue. Potency of buccal tablets is 2 times that of oral methyltestosterone.

Methyltestosterone is approved by the FDA for the palliation of androgen-responsive metastatic breast cancer in women who are 1 to 5 years postmenopausal or who are proven to have a hormone-dependent tumor noted by previous beneficial response to castration.

Female patients should be observed for signs of virilization. Women should be instructed to report any hoarseness, acne, changes in menstrual periods, or increase in facial hair. Discontinuation of drug therapy at the time of evidence of mild virilism is necessary to prevent irreversible virilization. A decision may be made by the patient and the physician that some virilization will be tolerated during the treatment for malignant disease.

 

 

Usual Adult Dose for Postpartum Breast Pain:

 

80 mg orally per day for 3 to 5 days.

 

Usual Pediatric Dose for Delayed Puberty -- Male:

 

10 to 50 mg orally once a day.
-or-
5 to 25 mg buccal tablet once a day. Buccal administration allows direct absorption of methyltestosterone into the systemic venous system resulting in delivery of unmetabolized drug to the target tissue. Potency of buccal tablets is 2 times that of oral methyltestosterone.

Dosages used to treat delayed puberty are generally started at the lower end of the dosing range and titrated according to patient response and tolerance. The duration of therapy should be limited to 4 to 6 months.

Wrist and hand bone age should be assessed prior to initiation of methyltestosterone therapy and every 6 months to monitor bone maturation. Exogenous androgen therapy can accelerate bone maturation without producing a compensatory gain in linear growth. Use over long periods can result in fusion of the epiphyseal growth centers and termination of the growth process.
