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 can promote the male sex organs and used in seedling stage sex change. 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.

Applications:

Methyltestosterone is an oral testosterone hormone, the first oral testosterone preparation and the first C17-alpha alkylated (C17-aa) steroid ever made. The compound has appeared over the years under numerous trade names, but perhaps the most well known Methyltestosterone compound of all time was Ciba's Metandren. Ciba's Methyltestosterone, while oral, was actually a sublingual form, which enhanced the bioavailability of the testosterone hormone. In fact, this form doubles the bioavailability compared to a tablet version and enables the individual to reach peaked testosterone levels in an hour. If Methyltestosterone is used in tablet form, it can take approximately two hours for peak levels to be reached, not to mention carrying a much lower potency.

While Ciba's Metandren was a successful product, this particular and most well known brand is no longer available. Currently, generic brands are primary as well as several underground lab preparations. The only name brand pharmaceutical based pure Methyltestosterone for several years has come out of Greece in Teston.

While Methyltestosterone is not as common as it once was on the pharmaceutical market, it is still used in some areas around the world. Oddly enough, while it has been pulled from many markets, while many U.S. physicians rarely prescribe it. Methyltestosterone is in high supply on the U.S. pharmaceutical market. The compound has been used to treat low testosterone and andropause in men, as well as cryptorchidism. It has also been somewhat successful in some breast cancer treatment plans, treating excess lactation post pregnancy and osteoporosis. Most interestingly, Methyltestosterone has had a fair amount of success in treating menopause by enhancing often lost libido and energy levels that often diminish during this stage of life for many women. While Methyltestosterone has enjoyed success in 

menopause treatment in the modern era, most women are now prescribed other testosterone forms. Creams and gels are perhaps the most common. Testosterone and progesterone mixed creams have been highly successful as well as subcutaneous implant pellets like Testopel.
