Description:
Methyltestosteron is one of the oldest anabolic steroids in existence and one of the most important anabolic steroids ever created. The testosterone hormone is the first anabolic steroid ever synthesized, and it was simply raw testosterone. The first testosterone compound was an injectable form with no ester attached; think Testosterone Suspension. In 1937Testosterone Propionate would hit the market, and it would be the first ester base testosterone compound. It would also be the first testosterone compound made regularly available for commercial use. However, a year before in 1936 Methyltestosteron would appear, and while it's not as common as it once was it still has a place in medicinal testosterone treatment plans.
Methyltestosteron is an oral testosterone hormone, the first oral testosterone preparation and the first C17-alpha alkylated (C17-aa) steroidever made. The compound has appeared over the years under numerous trade names, but perhaps the most well known Methyltestosteron compound of all time was Ciba's Metandren. Ciba's Methyltestosteron, 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 Methyltestosteron 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 Methyltestosteron for several years has come out of Greece in Teston.
While Methyltestosteron 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 Methyltestosteron is in high supply on the U.S. pharmaceutical market. The compound has been used to treat low testosterone andandropause 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, Methyltestosteron 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 Methyltestosteron 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.
While it has held a fair amount of success, Methyltestosteron is considered one of the more controversial testosterone medications in traditional medicine. This controversy largely surrounds its hepatotoxic nature, which does not exist with other testosterone compounds. Further, unlike most testosterone compounds you will rarely find Methyltestosteron being used in performance enhancing circles. Methyltestosteron like all testosterone compounds carries an estrogenic nature, but this form generally carries it at a far pronounced level and is simply a poor choice for most athletes.
