CAS 58-18-4 Androgenic Anabolic Steroids Methyltestosterone Raw Hormone Powders
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 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.
The androgens are steroids that develop and maintain primary and secondary male sex characteristics.
Androgens are derivatives of cyclopentanoperhydrophenanthrene. Endogenous androgens are C-19 steroids with a side chain at C-17, and with two angular methyl groups. Testosterone is the primary endogenous androgen. In their active form, all drugs in the class have a 17-beta hydroxy group. 17-alpha alkylation (Methyltestosterone) increases the pharmacologic activity per unit weight compared to testosterone when given orally.
Methyltestosterone, a synthetic derivative of testosterone, is an androgenic preparation given by the oral route in a capsule form. Each capsule contains 10 mg of Methyltestosterone USP.

Methyltestosterones can promote the male sex organs and used in seedling stage sex change. Methyltestosterones is a steroid hormone from the androgen and is found in mammals and other vertebrates, Methyltestosterones is primarily secreted in the tests of mails and the ovaries of female, although small amount are also secreted by the adrenal glands, Methyltestosterones is the principle male sex hormone and an anabolic steroid.
Methyltestosterones plays a key role in the development of male reproductive tissue such as the testis and prostates. In addition, Methyltestosterones is essential for health and well-being as well as the prevention of osteoporosis, Methyltestosterones is conserved through most vertebrates, although fish make a slightly difference from called 11-ketotestosterone.
Mechanism of action
The effects of testosterone in humans and other vertebrates occur by way of two main mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors. Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase.
DHT binds to the same androgen receptor even more strongly than T, so that its androgenic potency is about 2.5 times that of T. The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.
