17α-Methyl-1-Testosterone
Methyl 1-testosterone AKA 17aa-1-testosterone is the methylated version of the steroid 1-testosterone. This structural modification makes steroids much more orally bioavailable by inhibiting breakdown in the liver. Methyl 1-test doesn't convert to estrogen and is highly anabolic and moderately androgenic. When compared to orally administered methyltestosterone, methyl 1-test is 910-1600% as anabolic and 100-220% as androgenic. Reported side effects include lethargy, which can range from mild to severe, increased blood pressure, bloating, joint pains, cramps, mild headaches, insomnia, aggressiveness, and irritability. Many users also find that methyl 1-test decreases appetite, which can be harmful or beneficial depending on one's goals. These side effects can be reduced by lowering dosage or taking smaller doses more frequently. Another concern with methyl 1-test (and methylated steroids in general) is hepatotoxicity. Other substances that are toxic to the liver (such as alcohol) should be avoided to avoid placing extra stress on the liver. Milk thistle, alpha lipoic acid, and N-acetyl-cysteine are commonly recommended to help protect the liver. When taking methyl 1-test, it is best to start out with at least a week at a dose of 5-10 mg to see how you react. Many find a lower dose to be just as effective as a higher one, but with less side effects. Most seem to find their ideal dose to be in the 10-30 mg range. Cycle length should be kept short, in the range of 1-4 weeks.

17-alpha-Methyl Testosterone Application:
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.
