Steroid hormone breakdown

FIGURE 4-9. A general model of group I hormone action. The hormone binds to intracellular receptors in the cytoplasm or the nucleus and causes a conformational change. The hormone-receptor complex then binds to a specific region on DNA called the hormone response element. This interaction, with the help of various accessory factors and coregulators, results in the activation or repression of a restricted number of genes. The hormone response elements and associated factor elements are called hormone response units. The “bubble” indicates that this region of DNA is open or accessible to the transcription complex. These regions of DNA are often found to be sensitive to digestion by the enzyme DNase I.

I am a long-time user of various anabolic steroids but I have never looked back after a friend introduced this wonderful D-bol to me. Though I was already well built before I started taking D-bol, I experienced a significant increase in muscle mass. I had hit a sort of plateau phase with my usual steroids and was eager for something that would help me add a few more pounds of muscle. Dianabol did exactly that. As is the case with all anabolic steroids, you must be aware of the consequences of using too much of them without consulting a doctor. I frequently seek advice from my doctor about anything that has to do with using steroids to build muscle. So far I haven’t experienced any side effects and see myself sticking to Dianabol for many years to come.

The secretion of hypothalamic, pituitary, and target tissue hormones is under tight regulatory control by a series of feedback and feed- forward loops. This complexity can be demonstrated using the growth hormone (GH) regulatory system as an example. The stimulatory substance growth hormone releasing hormone (GHRH) and the inhibitory substance somatostatin (SS) both products of the hypothalamus, control pituitary GH secretion. Somatostatin is also called growth hormone-inhibiting hormone (GHIH). Under the influence of GHRH, growth hormone is released into the systemic circulation, causing the target tissue to secrete insulin-like growth factor-1, IGF-1. Growth hormone also has other more direct metabolic effects; it is both hyperglycemic and lipolytic. The principal source of systemic IGF-1 is the liver, although most other tissues secrete and contribute to systemic IGF-1. Liver IGF-1 is considered to be the principal regulator of tissue growth. In particular, the IGF-1 secreted by the liver is believed to synchronize growth throughout the body, resulting in a homeostatic balance of tissue size and mass. IGF-1 secreted by peripheral tissues is generally considered to be autocrine or paracrine in its biological action.

Cells of the zona fasciculata and zona reticularis lack aldosterone synthase (CYP11B2) that converts corticosterone to aldosterone, and thus these tissues produce only the weak mineralocorticoid corticosterone. However, both these zones do contain the CYP17A1 missing in zona glomerulosa and thus produce the major glucocorticoid, cortisol. Zona fasciculata and zona reticularis cells also contain CYP17A1, whose 17,20-lyase activity is responsible for producing the androgens, dehydroepiandrosterone (DHEA) and androstenedione. Thus, fasciculata and reticularis cells can make corticosteroids and the adrenal androgens, but not aldosterone.

The Story: In February 2005 Canseco released his autobiography and steroid tell-all, Juiced , Wild Times, Rampant 'Roids, Smash Hits, and How Baseball Got Big. In it he described himself as 'the chemist' having experimented on himself for years. He claimed to have educated and personally injected many players including Mark McGwire, Rafael Palmeiro, Juan Gonzalez, Ivan Rodriguez, and Jason Giambi. In his second book, Vindicated , Canseco added Magglio Ordonez to the list of players he had educated and injected with steroids. He also said he introduced Alex Rodriguez to a trainer/PED supplier after Rodriguez had asked where he could get steroids.

Testosterone Isocaproate will help in increasing the body weight and will also help in gaining the strength. It also helps in losing fat in the body and gives an increase in libido, red blood cells, stamina and quick recovery after heavy training. As told earlier it is very hard to be found in the market in its purest form but its raw powder form is available in the market in the form of Testosterone Cypionate and Testosterone Enanthate. Testosterone Isocaproate is useful in increasing the synthesis of protein in the body, reduction of the cortisol, increasing the ability to recover especially after heavy trainings, increasing strength and helps the person gaining more mass. It is also very efficient in both cutting and the bulking cycles. But as it is related with the family of androgen it will have aromatizing properties as well. Apart from these benefits it has got all other benefits associated with it which are also associated with any other testosterone
