  • Human Growth hormone (HGH), also known as somatotropin or somatropin, is a peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals. It is a type of mitogen which is specific only to certain kinds of cells. Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored, and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland. Many factors influence the release of Human Growth Hormone, however, including nutrition and exercise.  

    Tibolone has tissue -selective estrogenic effects, with desirable effects in bone , the brain , and the vagina , and lack of undesirable action in the endometrium and breasts . [14] Its tissue selectivity is the result of metabolism , enzyme modulation (., of estrogen sulfatase and estrogen sulfotransferase ), and receptor modulation that vary in different target tissues, and differs mechanistically from that of selective estrogen receptor modulators (SERMs) such as tamoxifen , which produce their tissue selectivity via means of modulation of the ER. [13] [14] As such, to distinguish it from SERMs, tibolone has been described as a "selective tissue estrogenic activity regulator" (STEAR), [14] and also as a "selective estrogen enzyme modulator" (SEEM).

    Muscles are important components of the human body. They are necessary for our harmony development and hight quality life. Elastic muscles make your body not only hard, powerful, but also beautiful. Athletes and professional bodybuilders decide to buy testosterone cypionate after they find out what great effects it brings to their body. But before you start using steroids for sale it you need to understand the importance of some special techniques known as post cycle therapy to avoid some unwanted side effects and to avoid any damage to your system.

    The double bond of cycloartenol (compound 7 in diagram) is methylated by SAM to give a carbocation that undergoes a hydride shift and loses a proton to yield a compound with a methylene side-chain. Both of these steps are catalyzed by sterol C-24 methyltransferase (Step E1 in diagram). Compound 8 is then catalyzed by sterol C-4 demethylase (E2) and loses a methyl group to produce cycloeucalenol. Subsequent to this, the cyclopropane ring is opened with cycloeucalenol cycloisomerase (E3) to form 10 . Compound 10 loses a methyl group and undergoes an allylic isomerization to form Gramisterol 11 . This step is catalyzed by sterol C-14 demethylase (E4), sterol Δ14-reductase (E5), and sterol Δ8-Δ7-isomerase (E6). The last methyl group is removed by sterol demethylase (E7) to form episterol 12 . Episterol 12 is methylated by SAM to produce a second carbocation, which loses a proton to yield 13 . This step is catalyzed by 24-methylenesterol C-methyltransferase (E8). Compound 13 now undergoes reduction by NADPH and modifications in the β-ring to form β-sitosterol.
